PERSPECTIVE PERSPECTIVE PERSPECTIVE
Much Has Improved When it Comes to Standards In May 2003, the late Claude de Tourreil, confidently predicted: “In some 3 to 5 years, engineers working with composite insulators should have at their disposal a coherent set of IEC Standards. All of the definitions, test methods and acceptance criteria common to the various types of composite insulators will be found in the ‘Common Clauses’ Document while those tests specific to any given insulator type will be listed in the specific standard for that type.” A year later, Claude became frustrated by what he saw as unnecessary administrative delays in this process, both within CIGRE and the IEC. “Recent pressures,” he wrote in his Commentary in the May-June 2004 issue of INMR, “often due to changed administrative policies, have now forced the people to do much of their volunteer work during the evenings and weekends. Were it not for their dedication to the scientific challenges involved, I think that many of these experts would probably have abandoned these efforts long ago.” Unfortunately, Claude is not here to see that things have improved a great deal since 2004 when it comes to the issuing and application of international standards. In fact, a broader and more complete set of IEC standards are now helping establish common dialogue and facilitate business transactions between suppliers and users of a wide range of electrical components across the globe. What’s equally striking is the fact that, according to IEC Secretary General & CEO, Frans Vreeswijk, 10 years ago it took an average of 6 years to issue a new standard. Today, that has been cut by more than half, to an average of only about 32 months.

EDITORIAL Appearance Becoming as Important as Reliability
In mid 1993, just weeks after launching INSULATOR NEWS & MARKET REPORT (whose name became INMR in 1999), I contacted a relatively small insulator supplier based in Switzerland. My goal was to arrange an interview with their CEO – Konstantin Papailiou – a reputed expert who had been involved in some of the earliest applications of composite insulators in Europe. We met at his office in the town of Malters, near Lucerne, a short time later and Konstantin proved an outspoken man. Although he knew I was a newcomer to the field of insulators, he talked at length about how composite technology was about to revolutionize overhead line and substation design. But after I’d left that autumn afternoon 21 years ago, he turned to his colleague, Manfred Peter, and said: “I give this guy 6 months.” Recently, I was re-united with Konstantin, although we did meet on several other occasions in subsequent years. In fact, in this issue is an article based on a 1999 visit where Konstantin and I together inspected a new 400 kV compact line segment near the Swiss town of Nyon. He is as gregarious as ever and today has attained international celebrity as the much praised Chairman of CIGRE Study Committee B2 (Overhead Lines). He has also just been awarded a special distinction, CIGRE Fellow, to honor his long and tireless work on behalf of the CIGRE community. We met at the Louvre reception during the past General Session in Paris and reminisced about the passing of years. He told me how pleased he was that his prediction about the fate of INMR (that’s how I found out about his remark back in 1993) had not come true. I invited him to be the Key Note Speaker at our 2015 INMR WORLD CONGRESS, next October in Munich – and he accepted. I’m sure Konstantin will offer an animated and provocative introduction to this event, which will feature over 100 speakers making expert presentations on today’s key topics relating to insulators, arresters, cable accessories and bushings. But there’s a strange irony in the fact that – for all the achievements in overhead line design made possible by superior technologies – one of the greatest challenges faced by power supply companies these days no longer comes from events such as pollution, icing, overvoltage or wind. Today, it seems, another key challenge comes from a public that is increasingly suspicious of power infrastructure in general and especially dislikes the commonplace lattice tower. Indeed, I think Konstantin will be one of the first to agree that making overhead lines less obtrusive and more pleasing to the eye is now one of the key imperatives facing the power supply industry in many countries. In fact, that’s why the 2015 INMR WORLD CONGRESS will feature a special session devoted entirely to how alternative structures can successfully replace lattice towers, while still being cost effective and, most important, being more acceptable to affected communities (see: www.inmrworldcongress.com) To illustrate, this 2015 BUYER’S GUIDE double issue covers one situation that could perhaps serve as a model for how one network operator managed to meet demands for strengthening and reinforcing their network while also successfully obtaining the necessary public support and approvals. Hopefully, this feature article will drive home the point that when it comes to overhead lines, appearance is fast becoming as important as function.

2014-11-13 4:33 PM
In his landmark (but now hard to find) book Insulators for High Voltages, J.S.T Looms offered the following insight: “The purchase price of insulators, especially those of glass or porcelain, is totally dominated by market forces and bears no relation either to technical importance of insulation on transmission lines or to the cost of replacement and revenue loss in case of failure. In other words: insulators are absurdly cheap. The emergence of insulator production in parts of the world where labour costs are much lower than in the industrial North has further increased the downward pressure on purchase price and upon the level of quality. However, a change of attitude towards insulators is now becoming apparent in some supply utilities. They start to consider true costs rather than merely purchase price …”
Reliability of Cap & Pin Insulators
If anything, the above observations seem truer today than back in 1988 when Looms first wrote them. Indeed, over the past years there has been large-scale restructuring of the industry supplying toughened glass as well as porcelain line insulators. Due to market forces, certain manufacturers have re-located production and opened new factories in low cost countries – sometimes accompanied by a corresponding loss of manufacturing experience. New players have also entered the business, some supplying insulators of questionable quality. Most products from such new players are offered at a lower price than brands with a quality track record. As a result, some of the power utilities who have purchased them have been underestimating their impact on total life cycle costs in service, e.g. in terms of additional required diagnostics and/ or more unscheduled maintenance. Service experience as well as laboratory research has revealed that there can be great variance in the manufacturing quality of insulators from new producers – even though these may have formally passed standard IEC test requirements. This was pointed out, for example, in paper B2.209 presented during the past CIGRE general session by power companies and test laboratories from the Czech Republic, Sweden, Norway and Finland. These organizations reported on the poor performance of certain families of low quality glass cap & pin insulators. According to the paper’s authors, it is very difficult to distinguish low quality from high quality insulators relying on standard IEC tests since insulators are usually ‘specially selected’ for type and sample testing. Moreover, they felt that the requirements for type, sample and routine testing are not stringent enough to always reveal lower quality insulators. Similar experience was reported within the meeting of SC B2 by utilities as well as a HV laboratory from Brazil. Indeed, additional tests to those proposed in IEC 60383-1 have now been added to the Brazilian national standards with the goal of ensuring higher quality insulators. Again, there is an implicit recognition here that what is now specified in IEC standards – especially sample tests – are not rigorous enough. In particular, based on experience and special research, additional sample test have been recommended when it comes to insulators made of toughened glass, including: • RIV tests in dry & humid conditions; • Steep-front impulse voltage test in air (a very important & selective test based on my experience); • Residual strength test; • Thermal-mechanical performance tests, with more severe test parameters; • Impact test. The importance of randomly selecting insulators for sample tests was also emphasized. For example, the tests referred to in paper B2.209 were carried out on 11 insulators from different manufacturers. These had been randomly selected from batches of insulators purchased in the past by the participating utilities to avoid making any ‘ad hoc’ purchases that might imply similar ‘ad hoc’ quality control by the manufacturer. Only 2 of the 11 types tested fully complied with the new test requirements.
Examples of condition of insulators after electrical & mechanical tests (from CIGRE Paper B2.209).
Although the above refers specifically to glass cap & pin insulators, I am of the opinion that similar conclusions could also be reached for porcelain discs. Although the manufacturing processes for both glass and porcelain insulators are well known and mature, they are nevertheless sensitive to even slight deviations. Careful selection of raw materials and proper quality control at every stage of production is fundamental to assuring high quality in each item coming off the line. And making sure that this is always the case can only be realized by increasing the severity of both sample tests and routine tests. Taking into account the evolution of the insulator industry in recent years and the growing body of available service experience, I make the following recommendations:
Pigini Commentary
• Enlarge the information available on reliability of cap & pin insulators, possibly leading to results surprisingly different from the past (see my Q1, 2011 column in INMR, comparing the reliability of composite and ceramic insulators). To this purpose, setting up a new WG within CIGRE SC B2 with a mandate similar to WG B2-57, set up to look at field experience with polymeric insulators, would be helpful. • Based on unsatisfactory field experience with certain cap & pin insulators, the outdated IEC 60383-1 (1993) will need to be revised to reinforce and update it, especially in regard to sample and routine testing.

De-carbonization of the electricity sector is now among the key trends driving the power supply sector across the globe. But there are unique challenges in shifting more and more to renewable sources. Key among these is the progressive move from large centralized generators with well-defined operating characteristics to distributed generation with far more variable capabilities. For example, the latter can range from a few solar panels on the roof of a homeowner to a vast array of offshore wind turbines. At the same time, the output from each of these renewable sources also varies significantly with weather conditions. Even if ideal, these can occur when demand is low. One cannot just ‘crank up’ the wind to compensate for sudden demand peaks.
Test Facility Helps Integrate Energy Storage into the Grid
Energy storage systems are the key enabler for integrating renewable energy into the grid but lack of globally recognized safety, performance and operational standards makes it difficult to prove the validity of any particular system.
From the World of Testing
Energy storage systems help smooth out differences in load and demand and therefore offer a solution to manage the inconsistencies in power generated from renewables. But these systems must themselves be successfully integrated into the grid. To do that, electricity supply utilities will need clear specifications, not only to better understand their capabilities but also to compare energy storage alternatives and select which best meets their needs. A myriad of such technologies exist, from batteries to flywheels. While each may have its own standards and specifications, these do not necessarily provide all the information that utilities require in order integrate them properly into their networks. For example, while dimensions and weight of a battery are key considerations for an electric vehicle, many more factors are important for utilities, including cost per kWh, total power rating, cycle time and expected lifetime of the facility. What’s more, energy storage systems not only have to store excess power generated by the grid, they must also be able to feed it back when needed. Acting this way both as a load and a generator effectively changes the dynamics of the grid. Instead of centralized distribution with flows in only one direction, today’s grids are becoming more like a mesh as power moves to and from individual nodes. Utilities will therefore need to better understand these changing dynamics and the full impact of storage systems acting either as a load or a source. Standards, Testing & Certification Successfully and safely integrating energy storage systems into electricity grids requires them to be certified and tested against standards. But with such a variety of existing storage systems and with new ones emerging all the time there is still no common set of standards for them. Rather, each technology has its own standards and specifications and this makes it difficult for utilities to compare benefits and drawbacks of any particular system. To define a common set of standards for storage systems, it will be necessary for all stakeholders in this field to work together. This will enable definition of recommended practices for system safety and performance and also create a ‘level playing field’ across the different alternative technologies. The good news is that this is already happening. As example, the New York Battery and Energy Storage Technology (NY-BEST™) consortium includes over 130 companies – from manufacturers to academic institutions, from utilities to technology and materials developers. It is also comprised of government entities, engineering firms, systems integrators and end-users. With this diverse membership, a strong ‘ecosystem’ has been established that encompasses all stages of energy storage product development and application. Testing We at DNV GL are members of this consortium. Our BEST Test & Commercialization Center in Rochester is a product of this collaboration and its diverse capabilities are already helping bring emerging technologies to market. For example, the Center now allows testing the complete range of battery and energy storage technologies – from single cells to complete systems with cycle capacities up to 2 MW. By providing access to these test facilities without burdening any company’s own labs or requiring them to make major additional investments, it offers a resource for all who develop and commercialize new battery as well as energy storage solutions. Moreover, by drawing on the know-how of its staff, testing and technology development are accelerated. Conclusion Energy storage systems are the key enabler for integrating renewable energy into the grid. But a gulf still exists between the long-term vision of utility companies and the rapid pace of development within the energy storage marketplace. The lack of globally recognized safety, performance and operational standards for grid-connected energy storage systems makes it difficult to prove the validity of any particular system and risks damaging the entire market. Fortunately, consortiums like NY-BEST and private initiatives such as our Gridstor Joint Industry Project are bringing all parties together to facilitate optimal and safe implementation of energy storage systems.

Over the next 3 years, recently established working groups (WGs) within CIGRE will deal with a number of aspects of polymeric outdoor insulation. For example, as discussed in Issue 103, WG B2.57 of Study Committee B2, Overhead Lines, will conduct a survey of operating experience with composite insulators and propose an application guide dealing with key topics based on practice by user utilities. This WG, headed by myself, has a membership of more than 30 experts. Similarly, WGs D1.58 and D1.59 within Study Committee Materials & Emerging Test Techniques will deal with evaluating the dynamic hydrophobicity of polymeric insulating materials under AC and DC voltage stresses as well as methods for characterizing the dielectric performance of polymeric insulating materials for outdoor applications. Both are headed by Dr. Jens Seifert.
New Working Groups to Deal with Range of Insulator Topics
Two other WGs have also been formed to cover related topics. One of these – D1.61 – will deal with Optical Corona Detection & Measurement. This subject is now of growing interest because, in certain cases, the use of composite insulators is being questioned due to a claimed insufficiency of applicable diagnostic techniques, especially when it comes to live-line-work. However, as shown in Technical Brochure 545, Assessment of In-Service Composite Insulators by Using Diagnostic Tools, a number of methodologies are available that can be used to evaluate the condition of components and equipment under operating voltage. Their use and applicability is summarized in the table below. Diagnostic Methodology/Technique

For example, UV measurements can be made during daylight (see Fig. 1) or using night vision cameras (Fig. 2) that employ different wavelengths for measurement – the first 240…280 nm and the second, 230…450 nm. Being able to make use of such equipment during daytime is a big advantage hence this measurement principle has grown increasingly popular. In recent years, several different types of UV cameras have become available. However, in most cases they do not offer a clear ‘yes’ or ‘no’ result in terms of identifying defective components. Rather, their use often requires knowledge and experience when it comes to correctly interpreting data, especially when the focus is on polymeric surfaces susceptible to ageing. Fig. 1: Measurement with daylight UV camera.
Fig. 2: Measurement with night vision camera.
Reporting from CIGRE
Also, ambient conditions such as humidity, temperature, wind and pollution by other sources of photons, are all critical to correctly interpreting findings. Based on this, the main duties of this WG will be defining measurement parameters and calibration and, if possible, deducing thresholds for specific line components as well as demonstrating typical applications. The work of this group will likely be mostly experimental and the Convenor is Nishal Mahatho from Eskom (nishal.mahatho@eskom.co.za). The other new WG, D1.62, Surface Degradation of Polymeric Insulating Materials for Outdoor Applications, has a designation that might initially sound alarming but should not be. In some cases, different types of degradation were observed on polymeric insulating surfaces after only a relatively short period in service. Some work in this regard was started within D1.27 and will be continued in this new WG. For the few cases known so far, there has been no common root cause or scientific model since the interaction between degraded material and operational stress factors has been mostly case-dependent. As such, it is important to generate more information about these phenomena in order to better understand destructive degradation mechanisms and offer recommendations on how to improve the specific material groups being affected. Beside a ‘theoretical’ risk evaluation by Failure Mode Effect Analysis (FMEA), this work will also be driven by experimental work including Round Robin tests, where degradation mechanisms are identified in principle. An example of such a degradation mechanism is acid attack on a polymeric surface. The Convenor of this WG is Dr. Bernd Komanschek (bkomansc@te.com). One additional note: At the recent 2014 session in Paris, a new CIGRE Fellow Award was presented for the first time. This award is for active participation and for providing a leading technical role in the relevant Study Committees. It is my pleasure to report that Dr. Konstantin Papailiou received this award in the field of Overhead Lines as Member/ Convener of several Working Groups and also as Chairman of Study of Committee B2, Overhead Lines, from 2010 to 2016. Congratulations to him!

The National Aeronautics & Space Administration (NASA) chronology lists many achievements since 1958. Ten years later, for example, images sent back from Apollo 8 allowed us for the first time to see our planet as an isolated blue marble against the inky background of space. This image had a lasting legacy – the realization that earth is our closed-system ‘spaceship’ and not an infinite sink for pollution and wasted resources. During the 1990s, NASA struggled with problems in mega-projects such as the Hubble Space Telescope. By contrast, an initiative to deploy relatively inexpensive satellites such as the Mars Pathfinder in July 1997 proved the merit of taking technical risks and delivering scientific value in more efficient ways.
More Years of Lightning Observations Added to NASA Dataset
Another notable example was the launch of the optical transient detector (OTD) satellite to sample global lightning activity. Starting in 1995 and ending as its rechargeable batteries wore out by 2000, the OTD provided our first dataset of lightning flash density, obtained with uniform spatial sampling over land and water. A second satellite – the improved Lightning Imaging Sensor (LIS) – began delivering data in 1999 but only within the restricted latitude range of ± 38°. In 2006, NASA consolidated the data from the OTD and LIS projects and placed it on-line as a dataset, with version number V2.2. Lightning specialists have lively discussions about the merits of using optical transient density (also OTD) data to measure cloud-to-ground (CG) flash density Ng. Optical flashes can be associated with either in-cloud (IC) or CG flash activity. If a particular storm or region has a relatively high ratio of optical transients from IC to CG flashes, then any global conversion factor would need local adjustment. Some countries use lightning location systems (LLS) that continuously observe large areas with high detection efficiency. These can be used to study the need to adjust the OTD/LIS dataset within the observation areas and help draw conclusions for regions without LLS. My initial evaluation of the OTD data was that they were better than thunder observations for estimating ground flash density. For the first time, we saw many detailed ‘orographic’ features, i.e. where the terrain affects lightning density, notably in the Saudi peninsula, northern India and Pakistan as well as large islands such as Cuba, Indonesia, Java and Jamaica. I also concluded that thunder day (TD) level was such a poor global predictor of OTD that it must be a poor predictor of Ng as well.
Example of high density in Florida, Cuba, Jamaica & other Caribbean islands.
The OTD data did have statistical problems in areas of low lightning activity, such as Canada. As example, an area of modest lightning density to the east of the Rocky Mountains is present in OTD maps but not as well defined in published Ng results from Environment Canada's LLS. In spite of these limitations, an overall conversion factor of Ng=OTD/3 or Ng=OTD/4, seems appropriate for discussion. The recent CIGRE Technical Brochure 549, Lightning Parameters for Engineering Applications, notes the use of the former equation in the IEEE Standard 1410/2010, which also gives the recommended maps of the optical transient density from the NASA V2.2 dataset to replace old TD (keraunic level) maps. An Internet search of <NASA lightning V2.3> will take the reader to the first update in the OTD maps since 2006, i.e. the V2.3 released in late 2013. As was the case for the V2.2 data, the mean annual flash density is provided in a 720x360 matrix with units of flashes/sq km/ year, covering a grid with 0.5 degree intervals in longitude and latitude. The V2.3 data analysis cleaned up some noise in polar regions but still retained one spurious observation that should be set to zero. In the latitude bands between 75° and 38.75° and -38.75° to -75°, there are no changes between 2006 and 2013 data.
Transient Thoughts
In the region of ± 38° latitude, where more LIS observations were collected, the graph shows there was no change in average density. This means that the LIS sensor has functioned well for the entire period. The additional years of observations in the new V2.3 data set provide more confidence in the initial results. As an illustration of recommended use, a high lightning density seen in Florida by both satellite and LLS can be used to calibrate similar regions of high density observed by satellite only in Mexico and Cuba. It has always impressed me that the satellite observations resolve the difference in lightning activity from northwest and southeast on the island of Jamaica, matching momentary outage experience at the Jamaica Public Service. I recommend that the new V2.3 dataset be put to use by readers who have no access to historical ground flash density data and tested by those who do have independent measurements of Ng. Yes, there is some uncertainty in converting OTD to Ng but the uncertainty in converting from thunder days (TD) to Ng is much larger. I would enjoy seeing the updated OTD values in any upcoming articles that describe how utilities around the world deal with local lightning risks.

Icing problems can have a severe impact on the safe operation of overhead transmission lines. Early in 2008, for example, extensive icing hit large areas of southern China. The rare but disastrous meteorological conditions led to outages on 119 lines at 500 kV, 348 lines at 220 kV and 888 lines at 110 kV. Moreover, an astounding 35,385 distribution lines were also affected, from 10 to 35 kV. In all, 8,381 transmission towers from 110 to 500 kV collapsed under the effects of the devastating ice. Due to the huge economic losses from this event, domestic R&D institutes, universities and power utilities all embarked on extensive research into the problem and issued recommendations on the most suitable remedial measures. As a result, most Chinese transmission lines today are better equipped to withstand icing. Combined with the fact that there has not been a recurrence of such extensive icing, these measures have helped mitigate the hazards to lines.
Impact of Icing on Transmission Lines
However, icing still ranks as one of the most significant factors affecting the reliability of the power system in China. In fact, based on recent data on transmission outages across the country, those caused by icing continue to account for about a quarter of the total. This suggests more work remains to be done. In general, the adverse impact of icing on overhead lines can be classified into two broad categories: one relates to the fact that ice formations on insulators decrease their electrical strength and can result in flashover across the surface at operating voltage – a process called ‘icing flashover’. The second involves breakdown of the air gap. Heavily iced conductors and ground wires lead to decrease in the air gaps between them. Similarly, ice shedding and sleet jumping (as ice on conductor melts) and conductor galloping from icing and wind, can both lead to air gap breakdown. Extreme icing could even cause broken conductors or toppled towers – events that result not only in extensive but also prolonged outages. During 2012, the incidence of icing related tripping of transmission lines in China stood at 221. Occurrence of icing related tripping on the network of the State Grid was 135, with an overall successful re-closure rate of 34.8%. Outages attributed to icing problems totaled 88 and analysis of these revealed the following: • 61 trippings (45.2%) were related to icing flashover of insulators; • 59 trippings (43.7%) were caused by conductor galloping. Based on these findings, it’s clear that icing flashover and conductor galloping are key issues to solve when it comes to effective protective countermeasures for the future. To mitigate the hazards of ice build up on conductors, power utilities have developed a variety of DC ice melting devices. This technology has already been applied extensively with good results and can also melt ice on ground wires that have been suitably modified to accommodate the devices. As for those lines where there is higher likelihood of conductor galloping, adding anti-gallop or phase spacers has been shown to improve their ability to withstand failures from galloping triggered by icing. Moreover, transmission towers situated in areas where icing problems have traditionally been most severe are now modified to enhance their mechanical strength and thereby improve the resistance of the entire line. Much research has also been devoted to preventing insulator strings from failing due to icing. The icing flashover voltage of V-strings or inverted V-strings is generally higher than that of I-strings. Moreover, placing several large diameter discs in the proper locations along an insulator string (referred to locally as ‘flower arrangements’), also helps prevent icing flashover. By contrast, use of composite insulators or coating with RTV silicone does not seem to have any significant benefit insofar as mitigating problems due to insulator icing.
Scene From China
Many companies are now conducting research on ‘super hydrophobic’ coatings with the goal of using this technology to raise the icing resistance of both conductors and insulators. While promising test results have been achieved in the laboratory, there are still practical issues that need to be resolved. For example, up to now there have apparently been no reports of successful application on any in-service transmission lines. The Shenzhen Graduate School Campus of Tsinghua University has developed a special semi-conductive silicone coating that can mitigate icing on insulator surfaces under glaze weather conditions. This technique, which relies on the heating effect of a small resistive current, is seeing trial applications across selected areas of southern China and up to now has demonstrated promising results.

At most air-insulated substations, the arrester mounted at the transformer is close enough to other equipment to provide effective protection from flashover. However this applies only if the breakers are closed. If a breaker is open, the insulators on its line side – including its line side bushing – are not protected. In this regard, installing line entrance arresters will protect all points within the station when critical breakers are open – and this applies to all system voltages, including distribution. In fact, because insulation withstand levels are lower at distribution voltages risk becomes even higher.
Importance of Line Entrance Arresters
It’s probably worthwhile defining a line entrance arrester since it’s possible other names are also being used to describe it. As discussed above, this terminology applies to an arrester mounted on the first structure on an incoming or outgoing line at a substation. I estimate that about 30% of all substations with breakers are currently equipped with line entrance arresters according to this definition. Possibly, some readers may ask: “why waste money on an arrester at that location?” Other might wonder: “I thought everyone used them?” Purpose of Line Entrance Arrester The basic role of a line entrance arrester is to protect a circuit breaker that is ‘open’ from any lightning surge that enters the station along a connected line. Since it’s generally accepted that breakers on incoming lines are usually not left open for long, one might conclude there is little cause for concern. True, breakers normally remain closed. But if there’s a lightning induced fault on the system, the breaker is called into action to interrupt it. That means it can be open for some 100 ms or longer whenever a line fault occurs. This may seem a short duration yet, when it comes to lightning, it’s quite long. Since most lighting events include multiple strokes, the resulting surge can present itself to the power system with anywhere from 2 to 14 independent surges of different magnitudes, each separated by some 50 to 150 ms. Open Breaker Scenario 1 This scenario occurs when there is no line entrance arrester installed. The time-lapse below describes the events of a lightning surge on a system with an open breaker:
Under-hung configuration line entrance arresters.
T0 Surge 1 – 1-100 kA strikes line T5 ms Fault detected on circuit T50 ms Breaker opens T100 ms Surge 2 – 1-15 kA, 50-150 ms between each stroke T100 ms Surge 2 hits open breaker T100 ms Bushing flashes over from voltage doubling effect because arrester on transformer is unable to protect it through open breaker. Bushing flashover is likely because, when the surge encounters an open circuit, it doubles in magnitude. Fortunately, lighting flashover does not always convert into a power fault since the power frequency voltage is not available on the line at this point. However, a lightning flashover can trigger other flashovers nearby due to localized ionized gas. If it does, there may be considerable resulting damage. By contrast, if a line entrance arrester is installed, the line side of the breaker is protected from flashover even if the breaker is open. The above scenario therefore changes to no flashover at the time subsequent surges enter the substation. Open Breaker Scenario 2 Another less subtle scenario exists when a peaking generator goes off-line. Since the breaker on the line side of the step-up transformer is used to isolate it, its line side bushing can flashover from the first incoming lightning surge. Basically, as long as a breaker is open, the transformer arrester cannot protect its line side bushing.
For retrofitting older stations, transmission line arresters can also serve as line entrance arresters.
Woodworth on Arresters
Line Entrance Arrester Configurations A line entrance arrester can be mounted in just about any configuration and still be effective. For example, locating the arrester close to the breaker is not necessary, although separation distance needs to be taken into account. The separation distance calculator included in ArresterFacts 024 at www.arresterworks.com can then be used to determine the farthest effective distance for installation. It should also be noted that an arrester located on the first tower from a station would probably not protect the breaker. The line entrance arrester can even be a transmission line arrester suspended from the first dead end insulator. And, if there’s still doubt as to the value of investing in this type of arrester, just consider the cost of replacing a breaker.

A range of interesting developments in the field of power cables and their accessories were discussed during the recent last CIGRE General Meeting in Paris this past August. Perhaps the most visible progress was apparent in the ever-increasing voltage levels for which HVDC XLPE power cables and accessories are now being made available. For example, one paper from Korea described development of an XLPE nanocomposite insulation compound that has been type tested for ±250 kV. In the same paper the development of a flexible joint for 320 kV application was presented. Such joints are important in order to allow submarine cables to cover much longer distances. Connection to the conductor in this case is accomplished by welding while the insulation relies on wrapping and vulcanizing tapes. According to CIGRE TB 496, the entire system of terminations, cable and flexible joints for ±320 kV are expected to be type tested this year.
CIGRE 2014 Sees New Developments in Cables & Accessories
At the ever-expanding CIGRE exhibition, ABB presented an entirely new XLPE cable for DC applications as high as ±525 kV. This represents a leap forward for extruded DC power cable since it will allow power capacity to be doubled versus ±320 kV – up to now the highest voltage for this type of cable. At the same time, the recent development of pre-molded joints with special patented stresscontrol systems as well as terminations for both indoor and outdoor installation ensures that a complete system is now available to transport more power over greater distances. Another important development when it comes to cable accessories has been the growing family of plug-in connectors available for high and even extra high voltage. In this regard, a paper from Argentina introduced a T-joint construction for 132 kV and 220 kV. This construction is based of 3 plug-in connectors on the cables ends as well as a stainless steel cylinder as the joint body with the female plug connecting system, which is filled with SF6. Also displayed at the exhibition were plug-in connectors from Brugg Kabel up to 245 kV and from Pfisterer up to 420 kV. Such plug-in connectors are the main components in a complete accessory program that consists of a termination for SF6 insulated switchgear, an outdoor termination, a straight joint and even a T6-joint. All this is now available for voltages up to 420 kV and conductor sizes up to 2500 mm² in either copper or aluminum.
One of the most visible signs of progress at the recent CIGRE was apparent in the ever-increasing voltage levels for which HVDC XLPE power cables and accessories are being made available.
A paper from France described a 110 km cable link in their 225 kV network that used 2000 and 2500 mm² enameled copper conductors. The delivery length of the cable in this case was increased from the previous maximum of 500 m based on 30 t drums all the way to 1400 m using 50 t drums. To reduce the induced voltage in the metal screen in the event of a short circuit, a special construction of joints was used in this cable, with direct cross-bonding or bonding to earth. The extrusion line for the HDPE tubes was a mobile PE extruder in a container with the cooling line installed under a tent close to the cable trace.
Focus On Cable Accessories
Yet another interesting development in the field of insulating materials for high voltage power cables was discussed in a paper from Italy that presented the application of a high performance thermoplastic elastomeric (HPTE) compound for 150 kV, called P-Laser cable. A field test is planned involving 500 m of this P-Laser cable in a 5 km XLPE line composed of 3 single core cables. This type of insulation can be produced without cross-linking and has already been in service in medium voltage applications in Italy, Spain and the Netherlands since a few years. Since experience so far has been positive, extension from medium to high voltage will represent an interesting experiment when it comes to making HV cables more cost effective.

UTILITY PRACTICE & EXPERIENCE
Aesthetic Tower Design Helps Danish Grid Operator Obtain Approvals for Important New 400 kV Line Not long ago, the Nordic country of Denmark became the first place in the world where the ubiquitous lattice transmission tower is no longer accepted for any power line construction. While relatively small and with a population of only some 5.6 million, what makes this development noteworthy on the international stage is that Denmark is a frontrunner in a trend that is already impacting a growing list of countries – namely public opposition to the building of new overhead lines.
more aesthetically pleasing structures, there is every reason to expect that the public will object less, if at all.
Fortunately, resistance to added power infrastructure by affected communities across the globe seems to relate much more to appearance than to function. In this regard, rightly or wrongly, the lattice tower has become a symbol of the blemish that overhead lines sometimes impose on natural landscapes. That suggests that if power companies can find alternative,
INMR visits one of the world’s most recent alternatives to lattice towers and meets with the industrial designers who developed the design as well as the transmission system operator who made use of it. Apart from valuable information on how to make new transmission lines more accepted by an increasingly wary public, this article also offers insight into the specification and application of insulators for these types of projects.
Of course, leaving behind the steadfast lattice tower is something that would probably never be driven by economics alone: time has demonstrated that these towers are cost effective and offer outstanding performance and service life. Indeed, that explains why they have remained in use, basically unchanged, for decades.

The origins of the new double circuit 400 kV Kassø-Tejle line that runs northward along the Jutland Peninsula lie in the longstanding goal of strengthening the interconnection between Germany and Denmark, and from there to Norway and Sweden. However, realizing this goal by means of another overhead line required overcoming strong objections by those who lived in this flat region of mostly small farms and historic towns. Energinet, the Danish grid operator, first began planning the line back in March 2009 with an environmental impact assessment, as required by regional planning authorities. This document proposed that the initial route for the new line would be aligned as much as possible with an existing transmission line between the two points. The first public planning then took place in June that year and Energinet was asked

to study different routes in terms of their expected effect on people, buildings as well as local wildlife and vegetation. Within 3 months, these alternatives were set out, each with a 400 meter wide planning zone. A second pubic hearing for the project took place between March and May of 2010 during which the environmental impact assessment was published and the public was
given a time frame to express their views as well as any proposals for adjustments. By the autumn of that year, the final environmental impact assessment and detailed route planning were both reviewed and within 6 months negotiations began in regard to compensating affected landowners. Construction of the line began around the start of 2013, with the project scheduled to be complete by November 2014.

The firm who developed the design of the stylistic structures used along this line – dubbed Eagle Pylons – is a Copenhagen-based firm of industrial designers whose background lay more in public works than energy. However, back in 2001, the founder, Erik Bystrup, was intrigued by a competition aimed at finding new tower designs for another sensitive transmission line in Jutland. Until then, like most of the public, he found himself driving along motorways looking out at what he refers to as “the vast amount of gear and steel elements that comprise modern power lines” and wondering Eagle pylons were designed for elegance and calm in a mostly rural landscape.

why these were not yet being replaced by more aesthetic designs. Says Bystrup, “it seemed clear to me that these structures were not being designed by people who cared all that much about the sky. Then, in 2001, when we were awarded not only 1st but also 2nd and 3rd prizes in the competition in Jutland, it made me realize that applying our design ideas to the power sector might prove an attractive proposition.” Bystrup talks about some of the initial concepts developed to make power structures better blend into their environments. For example, one of his earliest proposals, called the Sky Pylon, involved polished stainless steel monoliths that reflect light in every direction and therefore appear almost invisible. However, this design ran into concerns that motorists might be blinded by reflected headlights and therefore never actively pursued. The Eagle Pylon selected for the Kassø-Tejle project was a subsequent design concept that Bystrup says was expressly developed to convey a “calm elegance” and help a major 400 kV transmission line blend

into a scenic rural landscape. He explains that the final tower selected was based on a hot-galvanized cylindrical steel shaft and rhombus shaped cross-arms and represents a departure from what he originally proposed – namely weathering steel an alloy that among other ingredients contains a very small percentage of copper. According to Bystrup, there is rapid formation of an outer ‘skin’ on such masts that quickly stabilizes against further oxidation, thereby giving the structure an indefinite lifespan. Cost-wise, he estimates the alternatives of hot galvanizing versus copper steel alloy without galvanization are similar. However, from a sustainability point of view, he suggests that the copper steel solution is preferable since zinc from
the galvanized layer will leech down over the decades and contaminate the soil. Still, in this particular case Bystrup reports that local farmers did not want something on their land that looked rusty. Another point of departure from the original concept was the use of two cross-arms instead of a single longer one to support all the conductors. The decision here was also made by resident landowners and based largely on how far away structures could be sited from existing homes. Says Bystrup, “going with two crossarms in place of one increased the amount of steel and cost of each structure by about a third but, in the end, the decision was not financial but based on satisfying local tastes. My preference would have been the single cross-arm which would also have allowed us to reduce the height of the mast.” (bottom) Cable transition station along Wintrack line near Delft. 400 kV cable transition station at sensitive zone in north Jutland.

Alignment of structures along transmission line can be as important as aesthetics of each structure. Photos: INMR ©
Bjarke Jensen, a transmission engineer who is now with the substations side at Energinet but who was closely involved in planning the Kassø-Tejle line, explains that the policy adopted in Denmark since 2007 is that all transmission lines less than 400 kV must be placed underground. Moreover, while overhead 400 kV lines are still permitted, these must now be based only on single pole structures. While he estimates from local experience that the cost premium of burying lines is some 3 to 4 times in Denmark, Bystrup and colleague Henrik Skouboe believe that this factor is probably closer to between 6 and 12 times, based on data from the National Grid in the U.K. At the same time, Bystrup claims that transitioning from overhead to buried lines can often prove as much a challenge technically as economically. “We are now firmly committed to the business of designing aesthetic power structures,” he argues, “because experience tells us that replacing
Bystrup takes the interesting position that such transitions from overhead line to cable are actually more disruptive, both environmentally and aesthetically, versus simply continuing the overhead line without interruption. “Whenever you go underground,” he remarks, “you need a transition station filled with structures and equipment that can cover an area the size of a football field. The same occurs at the other end, while in-between is for example a beautiful town or valley. But from a purely aesthetic point of view, my opinion is that there would be much less environmental impact from simply letting the line run Notwithstanding Bystrup’s views on uninterrupted. In fact, if anything, the comparative future of cables such changes only add disorder versus aesthetic overhead lines, the new Kassø-Tejle line has been placed and a messy overall appearance by underground at three environmentally breaking the continuity.” sensitive points along its 166 km route.

Nor is it likely to appear anytime in the near future. The biggest problem is that it cannot be done effectively over long distances due to issues of induction and capacitance that require expensive reactors.” As example, he points to other power companies in Europe that have chosen to place even 90 kV lines above ground due to technical challenges linked with certain cable installations. He also emphasizes the high cost of dealing quickly with service interruptions whenever power lines are buried.

angle type of tower design could not succeed well with glass because it combines both tension and compression loading – something that is difficult to achieve with glass – especially for insulators angled at 45°.”
One of the interesting features of the new line has been the selection of only composite type insulators for all of its more than 500 structures. This decision represented quite a departure for Energinet, which until this point has relied almost exclusively on glass insulator strings. “We are a conservative utility,” says Jensen, “and have always used glass at 400 kV. However, while glass strings could have worked on suspension towers, the flying
For example, flying angle structures for route adjustments of from 4° to 10° along the line employ a matching pair of silicone insulators with 120 mm core rods so as to handle all the tensile and compressive forces. Says Jensen, “this is actually nice thinking when it comes to aesthetic line design because the conductor is fixed in place with exactly the same configuration of insulators in every case, including on angle towers.

jumpers, can prove “a little bit disturbing”. He also notes that while the tension insulator for each V configuration on flying angle towers could have had a smaller diameter rod due to less need for mechanical strength, Energinet wanted the two to be identical in order to achieve the best possible visual impact. The arcing distance of 3.2 m and total creepage of 12 m selected for these insulators was chosen to be the same as normally specified for glass strings operating in an area of mostly low contamination. “We could have specified less specific creepage for insulators made with silicone,” notes Jensen, “but settled on specifying the same parameters we normally use for glass.” Another issue when it came to insulator selection was reducing noise, which Jensen says also favored using composite types based on information he received from suppliers. Indeed, to keep
audible noise levels along the route as low as possible, Energinet also chose a three-conductor bundle when a duplex arrangement would have been sufficient to handle the load. “Adding a third conductor represented an additional investment for us,” he notes, “but these types of choices were governed by making the line as acceptable as possible to local communities – not by finding ways to control costs.” Construction of the new 400 kV line was assisted by the decision to use steel tube foundations, each equipped with a cement collar to protect the steel against water and passing farm machinery. According to Bystrup, this decision not only reduced typical foundation costs but also the time subsequently needed to erect each tower. For example, Jensen reports that such foundations can be hammered into the ground in only about 30 minutes. Then, following a standard procedure where all tower parts are
laid out in advance in the field, the time needed to erect each structure averaged only one day per team. The policy regarding prohibition of new lattice power structures adopted in Denmark in recent years has been a trigger for several related projects by Energinet, apart from the design of the aesthetic Kassø-Tejle line. For example, four 120 m high lattice towers that carried two 400 kV circuits from Jutland to the nearby island of Fyn since the 1970s have just been dismantled and replaced by a subsea cable. On the Jutland side of this new link, two new cable transition substations have recently been completed and are housed in a futuristic enclosure made of steel plate containing numerous holes. The cable terminations at these stations, like most normally used these days by Energinet at 400 kV, are silicone housed and oil-filled. Bystrup, whose firm was not involved in the design of these cable station

enclosures nor in a modernistic GIS switching station along the KassøTejle line, acknowledges that these structures may have a high design content compared to typical structures of the past. At the same time, he wonders whether the aim in each case should be not to make them standout but instead be as hidden and unobtrusive as possible – a goal his team always strives for whenever creating aesthetic new towers. Bystrup sees a number of lessons learned from the experience of this line that he feels apply to new such single pole lines going up anywhere in the world – including the award-winning 400 kV T-Pylon design his firm has developed for the grid operator in the U.K. One of these lessons is that the overall cost of each aesthetic tower is not nearly as prohibitive as some might imagine at the start. While Energinet’s Jensen estimates that each Eagle pylon came with a 30 to 40 percent cost premium versus the now-banned lattice steel tower, Bystrup argues that in fact it is only marginally higher if one looks at total installed cost. “Considering the large savings realized on foundations as well as the much faster erection times,” he claims, “this line's cost would have been close to the same as traditional structures if the one storey design had been chosen.”

Bystrup. “The sky belongs to us all and not only to landowners on which power lines are sited.”
Another lesson is that the final design of aesthetic lines should not be dictated only by those who live nearby or who might own the land on which towers are sited. Says Bystrup, “we are committed to the idea that affected landowners should not be the only ones who decide how power lines will look since the landscape in fact belongs to us all.” Bystrup’s firm is already working in co-operation with universities and manufacturers on next generation structures based on composite elements that will enable reduced tower heights while allowing conductors to be placed much closer together. He even foresees the day that these types of structures will not only look more beautiful and less obtrusive in any environment but may even help reduce classical transmission problems such as conductor galloping.

UTILITY PRACTICE & EXPERIENCE
Compact Design Allowed Line Upgrade Under Severe Restrictions What do you do when right-of-way restrictions make upgrading an existing 125 kV transmission line to 400 kV impossible using traditional design? That was the challenge facing engineers 15 years ago at Energie Ouest Suisse (EOS) – a Swiss power supplier whose name has since been changed to Alpiq. INMR visited EOS in early 1999 to see how this challenge was overcome by means of a novel compact line design never before used in the network and which also became one of the world’s first such applications at 400 kV. The experience discussed in this article seems that much more relevant these days given that finding corridors for new power lines or expanding existing line corridors to accommodate upgrades now usually involve years of negotiations.

In most places across Europe, the average time required to complete a new overhead transmission line project is now estimated at well over 10 years. The large majority of this long time frame is being devoted to overcoming public objections and obtaining all the necessary approvals. The situation is much the same in Switzerland, where environmental and other restrictions on new or expanded line corridors have been part of the electricity supply landscape for more than two decades. It was against this background that EOS engineers faced a daunting challenge to successfully complete the upgrade of an old double circuit 125 kV line running between Geneva and Lausanne. The line passed through rural areas with relatively high population density and, given extremely high land costs, it was not economically feasible to enlarge the existing right-of-way (i.e. 9.5 m on either side) to meet the requirements of a conventional 400 kV line, i.e. where some 15 m would typically be needed to each side.
Insulator assembly on upgraded 400 kV compact line.
The project aimed to convert the existing line to two 400 kV circuits, while also maintaining a single phase 132 kV railway feeder circuit on the same structures. In order to deal with these constraints, a short section of line had to be designed as a compact 400 kV line. This was accomplished using insulated cross-arms made up of standard composite tension

large to be practical. It also would not solve the dynamic requirements associated with the types of towers we eventually selected.â&#x20AC;? These towers employ a pivoting crossarm assembly since, had a fixed arrangement been used, an even larger cross-section would have been necessary to take the loads.
The rationale for specifying a hollow core insulator for the strut application related to the high compression forces from heavy 40 mm conductors operating where loads under critical wind and icing conditions exceeded the maximum 55 kN for the 76 mm diameter solid core composite insulators supplied 15 years ago (note: FRP rods for these insulators are today available in diameters of 130 mm and more). While porcelain insulators in such a horizontal Vee configuration presented an option, engineers were concerned that these would be too heavy.
According to the Swiss-based supplier of the insulators used on this project, one of the benefits of this design was being able to assemble complete cross-arms on the ground and then lift them into place. This reduced installation time for each to about 10 minutes and therefore only about two-hours were needed to completely install all cross-arms on every tower.
Said Michel Ammann, Chief Engineer at EOS at the time, â&#x20AC;&#x153;because of required clearances of 3 m, a porcelain insulator of such length that could handle the required compression loads would be too
The special towers selected for the short section of compact line were bi-dimensional articulated towers supported at the tops by the ground wire as well as the conductors
attached to them through the pivoting cross-arm arrangement. Articulation of the towers was deemed necessary in order to meet Swiss norms for a mobile system. These 56 m structures each weigh about 15 tons and were developed in Italy as the largest version in a family of towers used for 130/150 kV compact line applications. In addition to offering a solution to the low environmental impact requirement of the affected area, the towers also provided benefits by reducing the typical foundation costs for the heavier, self-supporting lattice type structures used elsewhere on the line. The height requirement of the towers was dictated by the need to maintain exactly the same electromagnetic field as existed with the previous 125 kV line. Ammann reported that each tower was between 20 and 25 percent more costly than the conventional lattice type design, primarily due

TV silicone material has been used to prevent pollution flashovers at substations for more than 30 years. More recently, this same remedial measure has also been adopted by power utilities worldwide to resolve service problems due to extreme contamination affecting line insulators. These days, there is even a trend to specify silicone coatings at the design stage rather than dealing with the requirements and costs of subsequently coating insulators in the field. While the

Selection of Coating Material
RTV silicone coatings are available in a range of different chemical compositions and therefore the impact of environmental and electrical stresses must be evaluated on each alternative material. In general, the addition of these types of coatings will result in a substantial difference in pollution withstand capability of an insulator, due to the hydrophobic nature of silicone. Still, coating longevity, performance and ageing ultimately depend on the ideal chemistry as well as on method and quality of application.
have conclusively demonstrated that erosion resistance can vary greatly among different coatings and favor those protected by means of added alumina tri-hydrate (ATH) filler. When dealing with polymeric insulating materials, ageing is always a central issue and composite insulators have been used long enough to give some basic indications based on field experience. According to engineers at Sediver, utility maintenance crews sometimes have to replace composite insulators after about 15 to 20 years of service (and in certain situations even less depending on product or environment). The principal area of weakness in the case of certain designs comes from possible erosion of the rubber housing and seals which are essential to prevent exposure of the core to moisture ingress.
Coating applied to a toughened glass insulator is fundamentally different from the basic design of composite insulators. While clearly looking for a material that offers the best erosion resistance, even should a coating become eroded or damaged, the integrity of the insulator is never at risk, i.e. whatever may happen to the coating does not compromise the inherent properties of toughened glass, which still performs no Screening of available silicone different from a non-coated insulator.

Among the initial motivations behind the development of RTV silicone coatings on glass were requests by utility maintenance staff seeking to maintain the benefits of glass on their overhead lines but also looking to avoid any requirement for periodic washing under challenging contaminated service conditions. For example, one of the benefits of glass insulators is the ease with which inexpensive yet reliable diagnostics can be carried out using unaided visual observation alone. This is in contrast to the more complex demands linked to inspecting other types of insulators and is especially valuable when it comes to ensuring safe live line working.

attention has been given to trying to ensure the best correlation between test results and actual field experience. In fact, one of the main findings from the different methodologies tested is how difficult it is to duplicate real conditions using short-term laboratory procedures. For this reason, several strings of coated glass insulators have been installed at outdoor

test stations selected because of their challenging environmental conditions. The target here has been not only to develop more knowledge but also to verify the consistency of results obtained versus those from laboratory testing. Establishing the proper balance between erosion resistance and hydrophobicity has been approached through a novel philosophy that aims to combine Hydrophobicity Classification from IEC TS62073 with an internally developed erosion class chart, designated Sediverâ&#x20AC;&#x2122;s CE classification. While initially only used internally, this classification system is now starting to be adopted elsewhere since it provides a relatively accurate measure of the dynamics between these key performance parameters.
Hydrophobic properties of alternative coatings are evaluated both through test results and observations made in the field. It should be noted that findings have to be viewed with some caution given the wide possible diversity among severe service environments, e.g. from the deserts of Peru to the coastlines of Sicily. Similarly, behavior under AC or DC has to be analyzed with regard to the specific implied stresses. Such information has been accumulated for almost 20 years and over the past decade a monitoring program covering over a million coated glass discs has been in force. This has included yearly evaluations of samples removed from lines. This work has confirmed good overall preservation of hydrophobicity including in service areas where washing cycles once had to be performed each quarter. The stress level encountered in these applications translates into some reduction of hydrophobicity around the pin area, which is expected given the electric field distribution prevailing in that region. For example, the hydrophobicity status of insulators after 7 years of service in a polluted coastal environment equivalent to level E7 (as described in the IEC 60815-1) can be explained by modeling electric field that shows that the pin section typically suffers more than the rest of the insulator. The overall hydrophobicity of these coated insulators, even at the live end, seems to be preserved and can be classified between WC1 and WC3. What is also clearly evident based on laboratory tests on short strings as well as on field observations is that the complete string never loses all its overall hydrophobicity performance. This in spite of some hydrophilic areas appearing on localized areas of individual units, mostly near the

this has also allowed measuring the stress gradient on the coating along the string’s length. Some units can be partially WC5, as discussed above, but overall the string remained hydrophobic in all the different service environments investigated.
Pollution Performance
Service performance has confirmed that the risk of pollution flashover has been largely eliminated by the use of coatings in place of any periodic washing. Given this, special focus has been placed on

In parallel to such visual and To help monitor the evolution of hydrophobicity comparisons, the coating performance along the string, level of desired low molecular weight species (silicone LMW) left in the RTV silicone coated surface after several years in the field or after thousands of hours in an accelerated ageing chamber has also been investigated. In this regard, a Soxhlet test has been utilized in order to allow a quantitative measure by extracting the LMW left in the silicone. While further such research will help to better understand the dynamics of hydrophobicity recovery processes, one major trend has already been confirmed through research. Although top and bottom surfaces are coated with the same material and surface thickness, there is a difference in the amount of LMW species remaining after a few years such that there is a noticeable decrease at the beginning of the life of the insulator (corresponding to the initial years in service). However, the trend indicates that a possible stability in residual LMW content of Top: Soxhlet testing the silicone coating is achieved over Chart shows evolution of LMW species time. One possible explanation – still content over years in service. being investigated – is that after an initial phase of settling, the level remains relatively stable, ensuring the necessary hydrophobicity as well as hydrophobicity recovery.
a geometric approach was established whereby the string is divided into 3 sections of length: bottom 25%; top 25%; and middle 50%. Up to now, only light erosion (i.e. type CE2) has been observed in the bottom portion of strings. Similarly, in regard to hydrophobicity, only some areas in the same portion of string have been affected. This demonstrates a high hydrophobic buffer effect and resilience of the silicone coating applied to glass insulators.

Field Monitoring
Various performance attributes have been monitored in the field including overall condition of the insulators, coating adherence, thickness, hydrophobicity and hydrophobicity recovery. There have also been measurements of pollution and its conductivity. Apart from the benefit of allowing laboratory test procedures to be calibrated against field findings, 63 INMR Q4 Issue 106.indd 63

artificial pollution tests to verify this. For example, clean fog pollution tests with solid deposit layers were performed at STRI in Sweden and the findings were later confirmed at the HV laboratory in Bazet, France. One of the challenges in this regard relates to the preparation and deposition of the contamination on a hydrophobic surface prior to testing, with or without recovery. Results confirm a substantial increase in withstand voltage compared to a non-coated string with a performance similar or even superior to an equivalent composite insulator.
DC salt fog tests at Sediver laboratory. Average U50% performance with base 100 for non-coated glass.
Additionally salt fog pollution tests (at 80g/l) in DC were performed on silicone coated glass insulators at the R&D laboratory in Saint Yorre. Once again, the coated insulators offered substantial improvement versus normal non-coated glass. This result is in line with findings from monitoring an actual DC line equipped with silicone coated glass insulators.
Future Developments
While R&D on RTV coatings is now concentrated on chemistry, ageing, performance and testing methodologies, there is also great value in continuing to monitor the condition of coated insulators in the field. Up to now there have been no reports of flashover, washing or replacement of any of these insulators. At the same time, the Sediver CE classification table and methodology discussed earlier is being ‘fine-tuned’ to better describe the real condition of insulators and this approach could one day form the basis for a standard method of evaluation. Better understanding the performance of silicone-coated insulators is also providing new directions for development. For example, testing and monitoring of insulators where the coating was applied only to the bottom of the insulator began several years ago and there are already successful applications in Latin America with such ‘undercoated’ insulators. Similar trials are in progress in North America and Africa with equally good results. This development may provide further opportunities for technical publications on the topic.

hile external design is essential to how reliably a surge arrester performs in service, its electrical characteristics depend largely on the properties of the internal metal oxide resistors. These ceramic disks are sophisticated electronic devices manufactured using complex technologies and, despite the important role they play, their key properties are not always well understood by those who specify arresters. Yet, much of the performance of an arrester is dictated by the disks. If they fail, so too will the arrester. The following article from a past contribution by industry expert, Roger Perkins, reviews some of the main elements when it comes to the design and production of MOV disks. Introduction

One can say that their For the development engineer in development was mostly fortuitous this field, the key challenge is to since they were the unintended determine the optimal number, type by-product of an attempt to create semiconductor metal surface barriers and composition of these various elements. The task is not easy since using polycrystalline zinc oxide and the effect of one is not independent silver electrodes. of the others and significant, often non-linear, interactions have to The disks were later adapted for be considered. Moreover, there is use in HV surge arresters by several companies, notably General Electric, not just a single varistor property to optimize but typically several, which conducted some of the each of which will influence arrester landmark research to understand performance. their behaviour. Statistical techniques to cope with The ’varistor effect’ is actually not this problem have been developed a bulk effect but rather a grain boundary phenomenon associated with polycrystalline, semi-conducting ceramic materials. While many models have been developed to explain it, perhaps the most successful has been the Double Schottky Barrier (DSB) model. The huge influence on current flow of very small changes in voltage – the inverse of which represents the primary characteristic of an arrester – is due to a process called impact ionization.
and these enable production engineers to come up with an optimal formulation for their particular material system as well as the ideal related manufacturing process. Nonetheless, it is important to note that not all MOV discs offered in the marketplace and used in the production of surge arresters have the same optimal properties as well as varistor characteristics. Some of the reasons for this are discussed below.
Role of Microstructure
Optimal formulation does not in itself guarantee a good MOV disk. While formulation might assure intrinsically good electrical properties, there are other performance characteristics that depend more on production process than on material composition. This is because manufacturing involves ceramic technology and the essence of a ceramic material lies in its microstructure. The key properties of all ceramics – and this applies to MOV blocks – are determined by their microstructure. Fig. 1 illustrates a typical varistor microstructure. To the untrained eye, it may not appear homogeneous, especially if one considers that: 1) grain boundaries are so important, 2) that the content of critical elements is measured in parts per million and 3) that current densities can exceed 90A/mm2 in arrester applications. Nevertheless, this device offers exceptional performance in spite of these constraints.
Optimization of Composition
The modern varistor block contains predominantly ZnO but also between a few percent and a few parts per million of at least 10 additional elements, each of which has been determined through experience to contribute to performance. Some of these dopants, which include elements such as bismuth and
Fig. 1: Typical ZnO varistor microstructure. Unusual appearance is caused by at least three different crystalline phases having different compositions. ZnO grains predominate and their uniform size and shape are important requirements. Not apparent, but more important, is uniform distribution of multiple dopants.

67 INMR Q4 Issue 106.indd 67
2014-11-13 4:34 PM
The area of the microstructure shown in Fig. 1 is only 0.02 mm2 and contains only 50 grains of ZnO. A key concern is that this same uniformity must persist over a volume of perhaps 105 mm3 as well as the huge quantity (300x106) of grains one finds in a typical MOV disk.

Fig. 4: Comparison between full-face metallization (top) and border-metallization. Even this good example of bordermetallization method clearly shows uneven edge of electrode compared to full-face method.
Fig. 2 shows a problem that can occur if the microstructure of a disc is not well-designed and controlled and in this case the defect resulted in failure under severe operating conditions. Ceramics tend to exhibit brittle fracture so that, if localized stress exceeds tensile strength, a crack will be initiated and expand catastrophically. Localized stress is influenced by defects, which, depending on their size and geometry, can magnify the impact of an externally applied stress. For example, a high current discharge through an arrester (such as from a 100 kA lightning impulse) subjects the MOV disk to heating rates of as high as 2.5x107 °C per second. Resulting thermal expansion generates inertial stress waves within the material whose magntiude depends on the MOVâ&#x20AC;&#x2122;s physical dimensions as well as the rate of heating. Longer disks generate higher internal tensile stresses than shorter discs and, should the material contain any microstructural defects (e.g. of the type in Fig. 2), these stresses will lead to fracture. For a symmetrically constrained disk, reflections of the stress wave will maximize tensile stress at the center and a characteristic mid-plane crack will form. Clearly, the manufacturing process must avoid such defects if an MOV disk is to successfully withstand current impulses of this magnitude. In addition to the above mechanical effects, a nonuniform current distribution through the MOV disk can lead to electrical failure. The current path is usually not uniform due to statistical variations in grain boundary properties coupled with the strongly non-linear conduction mechanism. Should the microstructure not be highly homogeneous, this effect is magnified and current paths can be formed which, due to the positive temperature coefficient of semiconducting materials, can lead to thermal instability and failure. Microstructural homogeneity is therefore essential and the manufacturing process must aim to always achieve it.

A. Metallized Electrodes 1. Mechanical Preparation Prior to metallization of an MOV disk, it is essential that precise geometrical conditions are fulfilled, namely that the surfaces are completely flat, plane-
Although material formulation and microstructure are clearly significant, these characteristics are not the only ones which must be carefully controlled when manufacturing MOV disks. The externally visible electrodes and circumferential coating (or collar) also play important roles in ensuring good performance.

parallel and perpendicular to the rotational axis of the disk. If this is not the case, a range of subtle problems can result. For example, adjoining electrode surfaces may not make uniform contact meaning that current injection into the metallization will also not be uniform. Potential differences will result which, under high current impulses, can lead to electrical breakdown of the tiny air gaps and to unnecessary erosion in the contact surface. The mechanical construction of the arrester itself, whether polymer or porcelain-housed, will also be sensitive to any deformities in shape of disks. Undesirable pressure points can generate fractures, while air gaps can lead to partial discharges and dielectric breakdown of the housing. The most effective way to avoid such deficiencies is through carefully controlling the grinding operation which precedes metallization. 2. Metallization The function of electrodes is to uniformly distribute the high currents that can flow through an arresterâ&#x20AC;&#x2122;s MOV disks during a nearby lightning strike and ensure a uniform current density across the varistor surface. Inability to achieve this will result in non-uniform heating, current channeling and hot-spot formation â&#x20AC;&#x201C; all potentially resulting in failure.
inevitable gaps between mask and disk surface allow some metal to leak through and to coat surfaces which should not be coated, such as the border and collar. Each of these problems could lead to non-uniform current or electric field distribution and the typical resulting failure mode will be puncture (see Fig. 3).
Other methods such as high-resistive coatings and flexible masks have also been devised to circumvent the potential problems described but each also has some deficiencies.

As with metallization, the simplicity of the circumferential disk coating (or collar) can be deceptive. Traditionally, polymeric coatings have been used because they are easy to apply. However, their performance is not always optimal since thermal degradation and poor adhesion to the disk surface can concern the arrester manufacturer. As the performance of arresters continues to improve, the maximum temperature excursions they experience in service also increase. A polymeric coating can soon become the weakest link.
In contrast to the above failure modes, which occur only within a single MOV disk, a further potential failure is linked with inter-disk contact in the presence of bordermetallization. In this case, the air gap generated at the edge of and between disks leads to high electric fields in the region, which in turn can lead to dielectric breakdown. An arc initiated here will generally strike the bare disk surface and inevitably generate a hot-spot that also leads to current channeling and puncture. For example, under poorly-controlled manufacturing conditions, adhesion An effective way to avoid these types between the coating and the disk of metallization defects is to use can be inadequate (as in Fig. 5). The full-face metallization (as in Fig. 4). disk surface will then be exposed With this technique, the edge of and start to degrade. Moreover, the disk forms one part of the mask in the case of porcelain-housed while the other part is semi-circular arresters, transverse fields caused and does not make contact with by severe external pollution could the disk. This arrangement is less lead to internal partial discharges sensitive to the problems described which can degrade some polymeric above. In addition, the complete coatings (see Fig. 6) and cause volume of the disk is utilized and the formation of corrosive gases. current distribution is uniform all the Polymeric coatings have proven way out to its edges. themselves less effective than glass coatings in preventing attack on the disk surface from such effects.
The most important property of the electrode is the degree to which it covers the surface of the disk. Traditionally, metallization has been of aluminum and applied using an arc or flame-spraying manufacturing process. A circular mask with diameter a few millimeters smaller than the disk is placed in contact with its surface using a methodology called border-metallization. However, there can be serious deficiencies in this technique. For example, the tolerance between mask and disk sizes and in the accuracy of positioning can lead to an electrode border having a non-uniform width. Moreover, the difficulty in cleaning the mask can lead to uneven edges. In addition, the high spray-pressure and

The ZnO varistor effect is strongly influenced by oxygen concentration at the grain boundaries of the DSB. Consequently, it is sensitive to localized changes in the partial pressure of oxygen, which can lead to rapid ageing of a disk and eventual arrester failure. It is important to remember that a varistor is a semiconductor whose electronic junctions at naked surfaces require correct electronic grading in order to prevent degradation or elevated surface leakage currents. The use of glass instead of polymeric coatings achieves this more effectively and prevents deficiencies. Glass will not degrade thermally and exhibits such low diffusion coefficients as to hermetically seal the varistor surface from all external chemical influences. However, glass coatings must be chosen carefully in order to fulfill this requirement as well as to be chemically compatible with the disk material i.e. not react with it at elevated application temperatures. Additionally, the glass should not contain hazardous components, such as lead, which will cause concern both in manufacture and in future disposal.
Quality Control & Test Procedures
It is evident that each step in the manufacturing process for MOV disks exhibits its own potential challenges if all required performance criteria are to be fulfilled. An integrated testing philosophy is therefore important. Statistical Process Control It is very the nature of an MOV disk that its properties cannot be adequately checked until the manufacturing process is complete. An alternative approach is to apply statistical process control to each step in the production process. In some cases the control parameter is obvious e.g. flatness, weight. In other cases, the intent is to identify and control those production parameters (Fig. 7) that are known to influence disk performance, e.g. temperature, cooling rate, atmosphere, pressure. Final Testing In spite of effective process control, it is still necessary to conduct extensive testing of MOV disks at the conclusion of the manufacturing process. The goal is to:
1. control those material parameters which impact performance in service, 2. confirm the protective characteristic, 3. ensure that design parameters are not exceeded, and 4. confirm long term behaviour. The following Table offers an overview of those tests which are normally carried out on MOV disks and explains how they relate to subsequent arrester performance. Type tests are not included in this overview but are specified in detail within the relevant IEC and IEEE standards. While these documents specify minimal routine tests, it is still necessary that the disk manufacturer extend this list significantly so as to be certain of satisfactory performance. At the same time, it is important to stress that arrester performance is determined not only by the MOV disk but also by its basic construction. For this reason, routine disk testing is by nature generic since it focuses only on basic performance characteristics. Arresters are designed around the disk and not the reverse. Therefore, safe arrester performance cannot be guaranteed by successful routine disk testing alone.

TESTING
Testing Organization Looks to New Opportunities in Changed Industry Landscape
T
he Feb. 2012 acquisition of KEMA – one of the energy sector’s best-known brands in independent testing, certification and consulting – by Norwegian-based DNV came as a surprise to most industry observers. Once owned by a consortium of power utilities, KEMA had a history going back all the way to 1927. In an interview with INMR in November that year, incoming CEO of DNV KEMA Energy & Sustainability, David Walker, explained that the motivation for acquiring KEMA related to what was perceived as the perfect alignment of high voltage and high power testing with DNV’s own business of testing and certifying marine equipment. He also noted that among the most visible immediate outcomes of the new ownership would be the investment in a pair of additional short circuit generators. Combined with the HP facility’s existing four generators, this added capacity would enable full-scale tests on equipment for the numerous super-grids being predicted for the future.
In September 2013, DNV merged with German-based GL Group to form DNV GL and this development added an even broader foundation to the organization’s diverse activities in the energy field. INMR travels to the Netherlands to meet with DNV GL executives and discuss how the focus on testing, inspection and certification (TIC) has been impacted by changes in the power industry and also to review plans for 2015 and beyond.

Verhoeven (left) and Fontijne. “Independent 3rd party verification quickly bonded KEMA to values at DNV GL.”
As DNV GL celebrates its 150th anniversary this year, management at the company’s KEMA Laboratories Division in Arnhem note that significant changes are already in place only one year following the merger. According to Jacob Fontijne, Executive VP of the Energy Power TIC Division at KEMA Laboratories, the old slogan, Experience You Can Trust is regarded as applying even more strongly today now that increased emphasis is being placed on certifying entire systems versus electrical components alone. Says Fontijne, “there is a clear connection between past work by KEMA in certifying individual components and our growing focus on ensuring that whole systems are independently verified as being able to deliver all that is expected of them. The key corporate value in the process has always been integrity and that links closely with the traditional mindset at DNV GL.” Bas Verhoeven is Director Power TIC, Arnhem and has been closely involved in the new generator investment project. As longtime past head of KEMA’s certification side, he believes that the rapid success of the merger was due to what he refers to as ‘common DNA’. “An independent 3rd party role is what links us closely to other units within DNV GL,” he
says. “In each instance, there is a need to be strict in conducting verification. The process of ensuring that something meets a particular standard must only be strengthened these days since the outcome of unavailable electric power can be social unrest. That means all components have to be proven to be of excellent quality.” The combination of KEMA’s former business with that of DNV GL has also facilitated expansion into growing new sectors within the power marketplace. Fontijne points out that while KEMA Laboratories already

knew much about testing cables, the new owners brought to the table knowledge of offshore infrastructure, such as oil exploration platforms equipped with their own transformers and cables. This allowed synergies in areas such as developing offshore sockets that wind farms can ‘plug into’ and which can then form a single link to a larger subsea cable versus the more costly alternative of individual cables coming in from many wind turbine installations. “For example, a large connector box can now be placed at sea,” explains Fontijne. “However, managing this task properly while ensuring high reliability is a challenge if you consider the environment of salt and high wind as well as the fact that repairs at sea are sometimes impossible. Another example is that DNV GL’s experience repairing subsea pipelines has given us access to the same technologies needed to repair subsea cable systems.” Fontijne points out that a full 5% of turnover is invested back each year into R&D activities such as developing floating wind turbines that can be towed in for maintenance when necessary. “It’s a great benefit for us to have this combination of ongoing innovation coming from DNV GL with KEMA’s already deep knowledge of T&D infrastructure.” 73

done their best to run a reliable and available system,” remarks Fontijne, “and this makes independent verification all the more crucial. One has only to look at certain places in Africa where blackouts are common due to inferior quality components and poor design.” Yet another factor impacting the field of energy testing and consulting has been what Verhoeven views
Another important development in the testing business has come from fundamental changes that have occurred in the power industry landscape. One of these, according to Fontijne and Verhoeven, has been entry into the energy field by independent investors. “It used to be that only utilities invested in power infrastructure,” says Verhoeven, “but now we see money coming in from other types of investors as well. Naturally, these new investors ask questions such as: will the utility take proper care and will the network be built efficiently and last as long as expected?” Fontijne believes this development is placing even greater emphasis on due diligence to ensure that power grids are not only well designed and constructed but also protected against external threats such as cyber-attack. There are other risks to manage as well, such as grid collapse due to ageing infrastructure. Says Fontijne, “all these issues again raise the question of whether entire systems are working properly versus just their individual components. That means that the systems element is only becoming more relevant since any failure can have such dramatic consequences.” Added pressure comes from regulators who also demand that performance standards are being met. “Utilities increasingly have to be able to demonstrate that they have
“Utilities increasingly have to be able to demonstrate that they have done their best to run a reliable and available system and this makes independent verification even more relevant.”
“But this is happening more and more these days,” says Verhoeven, “due to the pressures being placed on projects from the perspectives of delivery, price and performance. Based on years of experience, the overall proportion of tests we conduct that initially fail to
as the systematic loss of expertise within the power industry – the unintended consequence of years of downsizing and outsourcing. The tender process, he claims, often starts without adequate knowledge and therefore minimum technical requirements can sometimes be overlooked. One example of this is when the purchaser does not know how to properly evaluate a test report. “We are now working to change this,” explains Verhoeven, “by offering services such as free tailor-made workshops aimed at utility staff involved in purchasing key equipment for the grid such as circuit breakers. This includes what questions to ask and how to correctly interpret a test report. Engineers can sometimes be fooled by paper Fontijne. “Growing need to ensure entire certificates.” systems are working properly versus just individual components.” Photos: INMR ©
Verhoeven. “What’s needed in this business is right combination of facilities and people who have a tradition of testing and can deal with every test procedure.”
One power industry trend that DNV GL soon hopes to exploit is the move toward higher and higher system voltages. In fact, this development is the basis for the firm’s massive investment in two new short circuit generators, which when fully operational by the close of 2015 will make the Arnhem facility one of few places where UHV apparatus can be tested without relying on either synthetic techniques or modeling. But even with this new capability, Verhoeven cautions that the real strength of any test laboratory lies as much with the staff as with the equipment inside. “What’s needed is the right combination of facilities and people who have a tradition of testing and can deal with every test procedure.” For example, he notes that it is sometimes awkward running a test for a customer, who is present, but which results in a ‘fail to pass’ outcome. It can become even more problematic when that component happens to already be installed somewhere.

pass continues to hover around 30%, regardless of component or equipment. Most might have expected that this level would have gone down over the years, but in fact it is has remained stable.” Among the reasons for this, in Verhoeven’s view, is that there has been a trend to optimize materials and designs to be able to always meet the market price. At the same time, he says that he has heard stories that some apparatus is sold even before its design has been completed. “Still, with the possible exception of large power transformers, where initial failure rates are closer to 25%, we have seen that the figure of 30% is consistent across all other types of apparatus and components.” Another issue impacting the consistently high failure rate is the advent of new technologies in the field of power engineering. Verhoeven feels that such developments and associated new standards must be accomplished side-by-side. If standards are issued too early, they could block the freedom industry needs to innovate before arriving at the ideal product. But if they come out too late, newly developed equipment may not end up being adequately tested. “The current process whereby recommendations from Cigre become a new IEC standard along with relevant application and testing guidelines is a very good process,” says Verhoeven. “Every new standard needs to be based on input from the manufacturers who produce it, the utilities who use it and experts who can formulate an
“Based on many years of testing, the proportion of tests we conduct that initially fail to pass has always remained around 30%, regardless of component or equipment.”
adequate testing regimen. It’s really a delicate balancing act since if IEC kicks in too early, the standard can end up being too high or perhaps even too low.” Yet another factor now impacting changes in the testing needs of the power industry are environmental regulations that restrict SF6 gas to only certain applications. According to R&D Director, Rene Smeets, this has spurred interest in developing breakers that employ other combinations of gases, such as a new alternative being proposed by American multinational 3M. “This,” he explains, “means that there will be a need not only to test new designs of breakers but also equipment where the SF6 has been replaced by entirely new gases.” 75

circa Euro 70 million investment once finished, the first new generator will be installed in early November with the second in December 2014.
2.5 GW generator with 40 ton rotor spinning at 3000 rpm produces huge amount of energy that can be released in only 100 to 500 milliseconds. Environmental issues have also promoted the growth of vacuum breaker technology towards 50-70 kV and possibly eventually up to 150 kV. Smeets, who is Convener of a Cigre Working Group on HV vacuum switchgear, notes that this work will depend greatly on real tests, which he regards as vital and superior to modeling alone. “As a testing company”, agrees Verhoeven, “we need to be ready to certify such equipment and synthetic testing cannot be used for vacuum breakers since more physical power is needed. In fact, as in this case,
we are continually monitoring where the power world is heading. This is how we can be in the best position to test emerging technologies and also why we are continually investing in our laboratories as well as in measuring techniques. In this business, it’s all about bringing together what you need to measure with what your measurements actually say.” The most visible example of this philosophy in action is a large new structure still under construction alongside DNV GL’s existing high power laboratory. Representing a
Verhoeven claims that the KEMA HP laboratory is already the world’s largest short circuit facility, able to test up to 1200 kV full pole under real conditions. Still, he notes that with the upcoming super-grids of ± 800 kV and higher, some apparatus has become so large that even the lab’s existing four generators cannot handle the immense power requirements that might strain an entire grid.

“It’s not easy to build such a HP facility without at the same time affecting ongoing operations so for us it will be critical to phase-in the new with the old, while keeping our existing ‘shop’.” two more generators is expected to overcome this hurdle. A second rationale behind the investment, explains Verhoeven, lies in the already high utilization of the present HP facilities, which he states are being run ‘24/7’. “When I was asked to develop the business case for this new investment back in 2011,” he recalls, “the need for greater flexibility in meeting the needs of customers was also a key consideration. Then, when KEMA was sold to DNV in early 2012, they were especially interested in the power-testing sector and agreed quickly that this was a natural investment for us in order to remain ‘at the top of the food chain’ in this field in terms of people and facilities. Apart from the new generators, there will also be four new short circuit transformers for extreme high currents.” According to Verhoeven, acceptance testing of the new facility’s various
equipment will start early in 2015 and the extension will start off separate from the existing KEMA HP laboratories. Then, the final stage of the project will see the old and new facilities interconnected. Says Verhoeven, “it’s not easy to build such a facility without at the same time affecting ongoing operations, so for us it will be critical to phase-in the new with the old, while keeping our existing ‘shop’ open. We expect to be fully operational by the end of 2015, with all the flexibility needed to satisfy the great market interest in obtaining our gold KEMA Type Test Certificate for high end power transformers.” Apart from all the hurdles involved in completing this investment in added facilities, another challenge will come from developing the right test protocols as more and more testing is being done at UHV. “Although we have already begun doing tests on such equipment these past years,” remarks Smeets, “the concept of
‘super-grid’ is still not yet that welldefined. For example, super can refer not only to voltage but also size. That means we will have to design suitable test circuits as needs arise.” Smeets goes on to emphasize that the various equipment found in modern power grids are not simply ‘plug and play’ devices but rather must always be viewed in the context of the system as a whole. “In the end,” he says, “we see our mission will be much as it has always been: to give customers as much information as possible about their tests, including what phenomena made their equipment pass or not pass. In fact, if we see that any test is about to fail, we are able to stop it at an earlier stage. This gives the manufacturer much more insight into whatever may have gone wrong and is also an important added value to the cost of testing. It’s also one of the factors that we feel distinguishes us from some of the others in this business.”

Development & Testing of ExplosionResistant Cable Terminations
S
elf-supporting, fluid-filled terminations have been used since the very advent of HV cables and continue to be the first choice among most network operators due to their excellent long-term performance. Recently, composite housings have increasingly replaced porcelain in such applications and also come to represent the state-of-the-art for these components.
Although these types of terminations are usually reliable and safe, isolated cases of electrical breakdown can never be totally excluded. The worst-case failure mode results from a high temperature internal power arc that causes rapid vaporization and thermal expansion of the insulating medium. Due to sudden internal over-pressurization, the termination could easily explode, scattering debris and threatening collateral damage to nearby network The basic design of the latest generation equipment while also presenting a safety of fluid-filled terminations consists of a threat to the public. hollow core composite housing and a silicone rubber stress cone installed onto the Given this, cable accessory manufacturers cable insulation.

pressure release device. For example, one of the limiting conditions was that the device would have to be capable of releasing the pressurized fluid within only 2 milliseconds after arc ignition, while also offering the mechanical strength needed for prolonged, safe service at normal operating pressures. A way of best integrating such pressure release devices into existing designs of composite-housed terminations also had to be found. In the end, this was achieved by placing the devices at the top (i.e. integrated into the corona shield) as well as at the bottom of the termination (i.e. integrated into the base plate). Fig. 1: Positioning of pressure release devices at top and bottom of termination.
Internal Power Arcs on Outdoor Terminations
During a power arc inside a termination, the electrical discharge channel in the form of plasma leads to rapid transition of the insulating medium from liquid to vapor. The result is a sudden increase in pressure of the vapor phase, generating shock waves that stress the entire construction. If these dynamic stresses surpass the maximum mechanical strength of any of the terminationâ&#x20AC;&#x2122;s components (i.e. its hollow insulator housing, top and bottom flanges or the bolts that fasten it to the support structure), mechanical breakdown can occur. Debris can then be ejected at high velocity all around the installation. There are two possible options to address this problem. The first is to design a termination able to withstand even the high pressures
developed during an internal electrical breakdown. This solution, however, would require costly overengineering that would greatly restrict its economics and field of application. A more practical option is achieved through controlled release of the increased internal pressure during the early stages of a power arc. This would limit the maximum overpressure and resulting projection of any debris. To achieve this result, however, the termination would have to be equipped with embedded pressure release devices able to operate within only a few milliseconds of ignition of the internal arc.
Design of Pressure Release Devices The main challenge during the development phase of this second option was designing a reliable
Although having different shapes, both devices are designed to act similarly upon a burst disc but with different dynamics. In order to minimize work devoted to experimentation with different concepts, which then took place only during final product development, the design phase relied heavily on finite element analysis. In order to also function as a corona shield, the pressure device at the top of the termination took the shape of a cap with 8 grooves that break at a predefined mechanical stress, allowing the cap to open like a tulip (see Fig. 2). The pressure device placed at the bottom of the termination was integrated into the terminationâ&#x20AC;&#x2122;s basic design and supported by pins fastened to its base plate, as shown in Fig. 3. Should a predefined pressure level be reached, the disc is expelled in an axial direction towards the bottom of the termination.

In order to be certified as resistant to the impact of internal power arcs, a cable termination for system voltages up to 150 kV has to be tested according to European standard HD 632:2008 S2, which stipulates that, upon completion, no debris can be found beyond 3 meters from the test object. Since no equivalent standard for higher voltages still exists, the same requirements and testing procedures can be adopted. The internal arc test is conducted for duration of 0.5 seconds. It is performed in a singlephase test circuit with 20 kV supply voltage and a symmetrical 50 Hz short-circuit current of 63 kA, provided by a 2500 MVA power generator. To induce the internal power arc inside the termination, the test set-up consists of shortcircuiting the cable conductor to the cable screen using a 1.5 mm2 copper wire prior to final assembly of the termination.
Field Installation

Installation of explosion-resistant outdoor terminations requires no special measures on-site, apart from reinforcing the support to counter the force following rapid release of oil. By following the unitâ&#x20AC;&#x2122;s basic modular configuration, this type of termination can be installed in basically the same manner as a conventional unit. Both pressure release devices are pre-assembled at the factory under strict quality control procedures prior to delivery. This serves to minimize any potential for error during installation in the field. Market acceptance of this new safety design has been high. For example, shortly after release onto the market, some 20 units for 150 kV and over 50 units for 220 kV cable systems were installed by Italian grid operator, Terna. Demand for explosionresistant outdoor terminations from Brugg Kabel has since increased significantly, with more than 120 installations annually for voltage systems up to 245 kV.
Conclusion
245 kV cable termination system installed near highway.
Integration of an overpressure release device into the usual design of composite outdoor terminations offers a solution to minimize risk of injury or collateral damage in the event of an internal arc in oil-filled outdoor terminations. Ease of installation and no special requirement for additional maintenance versus other terminations allow this product to be easily integrated as a standard component in any network. The only basic requirement is some reinforcement of the steel structure to counteract the pressure wave from an internal arc. ď ¸

FEATURES: Design of high voltage equipment and other devices utilizing electric fields require accurate calculation of the electrical stress in order to reduce flashover or meet many other design criteria. Unlike most other physical disciplines, often a very large air space around the electrical device has to be included in the model. Thus, special modeling techniques like the Boundary Element Method have been developed which makes the solution of these very challenging problems a simple matter. Dividing 3D space up into millions of brick or tetrahedra becomes a thing of the past. Instead, the surfaces of the electrical components are the only places requiring discretization. - Electric field analysis - Skin and proximity effects in conductors - Magnetic force calculations - Simulation of real world transient test conditions like lightning strikes - Thermal analysis Optimization through parametrics or scripting. Established in 1984, Integrated Engineering Software is a developer of hybrid simulation tools for electromagnetic and particle trajectory design analysis. Integrated provides a line of fully integrated 2 and 3 dimensional simulation software, with thermal capabilities and system simulation for a multidisciplinary approach. Accurate and easy to use, Integrated’s products allow engineers and scientists to help reduce design cycles, save time and money and deliver products to the market faster.
