PRESIDENT’S Report
From the Office of the National President ENGR. ARMANDO R. DIAZ
President’s Message I
ndustry and technology steadily grew into a comfortable level in the Philippines during the last thirty years. To sustain its growth and enhance development, new knowledge is essential. The best source of information in this field is experience and expertise shared by eminent technological people. The Institute of Integrated Electrical Engineers (IIEE) of the Philippines grouped engineering professionals in fellowship and warm friendship and took advantage of the camaraderie to provide the needs of the country. The friendship developed within inspired us to work together, discover new ideas, inventions and contraptions; as well as learn from one another, and make use of each others network of knowledge sources. With these in mind, we created the Four-Circuit Program for this year to strengthen the bonds of IIEE's members some more and make it the muscle of the Institute’s potency. The program aims to ensure professional excellence among its members to meet the standards and values of state-of-the-art technological requirements. Ecological balance and sustainable energy, which is now an everyday concern, is a challenge to everyone. The Four-Circuit Program endeavors to face this head-on with the pooled proficiency of our able members. And since we have gigantic tasks ahead, we have to prepare ourselves, restudy our policies and guidelines, and rework non-functional policies and create more relevant directives. We are committed to give the Institute a new image that would reflect its proficient capabilities as an important part of nation building Let us all work together. Excellence in any art of profession is attained only by hard and persistent work.

Electrical Safety and Enforcement Awareness Campaign:
A Timely Advocacy
The Institute of Integrated Electrical Engineers of the Philippines, Inc. (IIEE) together with
the International Copper Association South East Asia (ICASEA) launched the Electrical Safety Enforcement and Awareness (ESEA) Campaign Project on May 21, at the IIEE National Office, Cubao, Quezon City. The launching carried the slogan, “Electrical Safety Starts With Me!” and participated in by the IIEE Officers and representatives from various government and private agencies in the industry. THE BACKGROUNDER According to the compiled data of fire incidents by the Bureau of Fire Protection, 10,773 fire incidents occurred in 2010, resulting in a total damage cost of PhP3,933,920,761.21. The top three major causes of fire incidents in 2010 were electrical connections, electrical appliances and electrical machineries. In Metro Manila alone, 1,676 fire incidents caused by electrical connections were recorded. With this, the ICASEA and IIEE entered into a joint undertaking through the ESEA Project to prevent the increasing rate of fire incidents due to electrical system problem . The ICASEA collaborated with the IIEE as the key facilitator for the strategic

planning, establishment of steering committee, and the implementation of the project in the country. Thus, the ICASEA and IIEE signed a Memorandum of Agreement (MOA) last February 10 at the New World Hotel in Makati City. The MOA ties these two organizations in implementing this program. Through the ESEA campaign project, certain strategies will be developed by the steering committee to enhance the enforcement of the Philippine Electrical Code to ensure electrical safety among the various types of establishments nationwide. The ESEA Campaign is designed to enhance the enforcement of the Philippine Electrical Code Part 1 (PEC 1), provide capacity building to improve the skills of local inspectors, increase the awareness of and educate the public on the importance of electrical safety, and strengthen the institutional cooperation between government and industry such as the local government units, developers, and contractors association, among others. The PEC 1 contains the “provisions which is considered necessary for safety and is used as basis for legal enforcement in the installation of electrical system design in the country” (PEC 1 2009 Edition). Compliance with the code will be an

With an objective of disseminating the information regarding the ESEA Campaign project to a diversified number of audience, the Institute called for a press conference to promote the project, in cooperation with the different media companies in the country. An article by Mr. Rudy A. Fernandez was published in the Philippine Star last June 13, with the title, “No Such thing as faulty electrical wiring, says IIEE”. The article featured the launching of ESEA campaign project and the statement given by the Institute that there is no such thing as faulty electrical wiring. It was quoted in the article that “faulty electrical wiring (FEW) as a cause of fire is just a scapegoat, an excuse for a fire incident with a yet unknown origin”. Also written in the said article was the statement from the IIEE that “an electrical system won't work nor function, if, in the very first place, it is faulty”.

Technical Feature TROUBLE SHOOTING OF ELECTRIC MOTORS
Safety Precautions
A Technical Paper from the Electric Power Research Institute (EPRI)
When
there is a motor failure, often there is tremendous effort expended answering why a motor failed and when it can be returned to service. Depending on the particular application, a motor failure may not have any impact on continued plant operation. However, due to technical specifications or regulatory commitments, an entire operation may have to be brought to a halt until a particular motor can be declared operable. Regardless of the actual or assumed urgency, unsafe acts either from personnel, equipment, or a regulatory point of view should not be the accepted practice. 4.1 Personnel Safety Before any equipment is inspected, the person performing the inspection should be sure that the situation is safe. If a motor has had a fault, and before it is physically touched, one should be sure that the motor does not present a shock hazard to anyone that will be working on a particular motor. Practices, such as assuring the motor has been checked, properly grounded and the power source removed, as a minimum should be done before actual physical work can begin. Hearing protection may be required when inspecting a motor that is operating. One possible exception to this precaution is the fact that many times abnormal sounds may be an indication of motor problems. Making note of abnormal sounds may be useful in the troubleshooting process. Guarding (barriers) should be done to prevent personnel from the motion hazards associated with rotating power equipment. Personnel that have access to this equipment should be protected from injury that might occur by being in the proximity to this type of equipment or against defeating protective devices without proper authorization. The primary purpose is protection against

bodily injury from moving parts or other hazards.
problem or condition of a motor rather than introduce new problems.
The following principles for effectively protecting or guarding equipment for personnel safety is as follows: • Understand operating practices related to equipment • Any methods used for guarding should provide safety to personnel •Any methods should take into consideration any unusual operating or maintenance situations • Consider the type of people that may be exposed to equipment, including any observers • Guarding methods should be effective without impacting practical use of equipment • Provide ease of access and prevent inadvertent operation
Excessive starting should be avoided because of the potential for damage to the motor, especially the rotor due to overheating if excessive starting is done in short time periods.
When involved in troubleshooting rotating equipment, personnel should be motivated to maintain safety practices and not expose personnel to hazardous conditions. 4.2 Operational Safety If during the troubleshooting process, there is a need to energize equipment, isolation from the load or system may be necessary such that the troubleshooting activities will not affect other plant systems during the check-out process. Care should be taken for activities that may require in-plant testing. Any isolation from controls should be taken into account to avoid inadvertent indications in the plant, such as lock-out or other system actuations trips during motor check-out. 4.3 Equipment Safety When troubleshooting equipment, the responsible person should ensure that any activities, such as testing do not further damage the equipment. It is the goal of the process to diagnose the actual

Equipment grounding should be maintained. Often grounding is done to limit voltages due to abnormal voltage conditions, unintentional contact with high voltage lines, or to stabilize voltage during operation. Grounding is usually done in accordance with National Electric Code guidance or other industry practices. Motor surface temperature is a function of the type of motor enclosure, method of cooling, class of insulation, and the operating environment. Depending on the type and application, the surface temperature of a motor may reach levels that could be hazardous to personnel. Excessive temperature could be an indication of service problems such as overload, stall, cycling or fault conditions. Other conditions that could lead to increased temperature are blocked ventilation openings, high ambient temperature, and/or unusual voltage conditions. The Electric Power Research Institute, Inc. (EPRI) conducts research and development relating to the generation, delivery and use of electricity for the benefit of the public. An independent, nonprofit organization, EPRI brings together its scientists and engineers as well as experts from academia and industry to help address challenges in electricity, including reliability, efficiency, health, safety and the environment.

Technical Feature
The 400 Volts System Engr. Jesus C. Santos
Vice Chairman, PEC-1 Committee Chairman, Technical Information Committee
It's good to know that some electric
utility companies, particularly Meralco, Benguet Electric and San Fernando Electric Light and Power, have already included the 400Y/230V ratings in their electric service standards. It is hoped that all other electric utility companies will follow. The whole idea is to have a single phase 2-wire line-to-ground circuit in order to concur with the Code provisions in Sections 2.0.1.2 and 2.50.2.7. Even before the electric utility considered the 400Y/230V rating in their electric service standards, the author had already made modification on the wiring design examples, which featured 400Y/230Y 3phase 4-wire wye and 230V single phase 2-wire, one conductor grounded, electric service as illustrated in PEC-1 2000. The PEC-1 editions before year 2000 were copied from NEC which illustrate lighting and small appliance loads rated 120 volts. The author modified the wiring design examples in PEC-1 to suit the 230 volts rating of lights and small appliances in our country with 230V 2-wire, one conductor grounded, circuit as his first step in pushing for 400Y/230V electric service consideration. The author's advocacy is to have a Code that concurs with the practice considering safe use of electricity. If only the city and municipal electrical engineers would take appropriate
30
action to push the 400Y/230V 3phase 4-wire or single phase 2-wire line-toground system, the time will come when the installations in our country will be compliant with the above mentioned Code provisions. It should be noted that the developers are finally convinced and so their commercial establishments and high rise condominium buildings are now functioning with 400Y/230V utilization voltage. Although, one may say that it's because of the savings which made them realized that such is the appropriate utilization voltage within their establishments, safety features that is inherent in the wiring installation is there unnoticed. Now that single phase line-to-ground is becoming common in building wirings, it is about time for the electrical contractors to educate their electricians on proper terminations of the grounded and ungrounded conductors. It should be noted that most appliances are provided with supplementary overcurrent device in series with one of the supply conductor terminals which is supposed to be the ungrounded conductor. Moreover, it should be noted as well that convenience receptacle and corresponding plug blades are polarized and the terminals screw shell of lamp socket are color coded with the intent of identifying the grounded conductor. The electricians should be familiarized with the proper terminations.
2nd QUARTER 2011 THE ELECTRICAL ENGINEER
There are still new designs that feature 230Y/133V electric service with 230V single phase 2-wire circuit both conductors ungrounded which supply small appliance loads and lights controlled by single pole light switch. Hence, one conductor and the corresponding luminaire terminal is still live even if the switch is off which is a condition that violates the Code. The rule intent is to cut-off all ungrounded conductors from its supply when the circuit is switchedoff to prevent electric shock when servicing the appliance or luminaire. Electricians working above ceiling are exposed to electric shock hazard when replacing the ballast of a luminaire even if the single pole switch controlling that portion of that lighting circuit is off. Since it is a new project, the design featuring a single phase circuit with both conductors ungrounded should have not been approved and the wiring permit should have not been granted by the authority having jurisdiction. Talking of economic impact on the installation, it has been validated in all newly completed projects that 10% up to 15% savings can be realized in installations with 400Y/230V compared to those with 230Y/133V or 460Y/266V utilization voltages. For example, the full load current of a 1000kVA source 400Y/230V will be 58 percent of the equivalent 230Y/133V electric service. So the size and cost of main circuit breaker and busway of a high rise condominium building,
Technical Feature for example, will be significantly reduced. Savings on branch feeder conductors and circuit breakers follow plus savings on panelboards inasmuch as the single phase line-toneutral circuit will have single pole only instead of a two-pole circuit breaker in a line-to-line circuit. The same holds true in commercial establishments. Greater flexibility in normal and emergency intertying configuration can be attained by having direct 400Y/230V (scheme-1) compared to tandem 460Y/266V and 400Y/230V (scheme-2) or tandem 460Y/266V and 230Y/133V (scheme-3) utilization voltages. Thus, a single unit standby generator, or generators in parallel, will be able to serve the loads directly in scheme-1. At least two units standby generators are needed for scheme-2 and scheme-3 to be able
to serve the loads directly. If single unit 460V standby generator, or 460V generators in parallel, will be employed in scheme-2 and scheme-3, 460V-230V stepdown transformer(s) will be required which means double voltage transformations which will in turn draw additional cost for electricity consumption due to core losses. Worst in this configuration is that 460V generator(s) cannot serve the 230V loads directly in case of transformer breakdown. The Institute of Integrated Electrical Engineers (IIEE) is conducting technical seminars, and "The 400 volts System" is one them. It is scheduled to be conducted this coming September in a more detailed graphical presentation which will include wiring design approach examples.

Electrical Fire
By Jules S. Alcantara, Professional Electrical Engineer Electrical fires claim the lives of many and destroy hundreds of millions of pesos worth of properties annually.
Electrical fires usually start with an insulation failure causing a short circuit and ends with fire. The root cause is usually a defect or deficiency introduced at some stage either in manufacture, installation and/or maintenance of electrical equipment, wires or devices. Another common root cause of fire, which is outside the responsibility of electrical engineers, is the misuse of and carelessness in the use of electrical equipment and appliances. Cases of misuse of appliances causing accidental electrical fires include: • An electrical iron left ON and pressed on the ironing board; • An electric kettle used for making coffee in an office with paper files, is filled with water, switched ON and then forgotten; • An electric hairdryer kept ON and placed on the bed; • An electric fan ceased to turn due to blockage or jamming of its blade by a material such as window curtains or has defective cords due to rubbing off of its insulation. The most significant factor in fire incidents due to electric fans is the location of the fan. Placing the fan near window curtains or on top of combustible materials such as paper or clothing are major causes of fire incidents involving fans. A fan placed in a location such that its cord may be damaged by passing persons or by objects on top of the cord may result in insulation failure; • Repeated blowing of fuse due to overloading which was “solved” by the user using a higherrated fuse or even replacing the fuse with copper strands.
Such practice eliminates the protection of the electrical system. To prevent fires, all wires and cables must be protected by a protection system of fuses or circuit breakers of appropriate rating determined by a licensed electrical practitioner. Improper replacement of fuses or circuit breakers is inviting a fire accident to happen; • Misuse of ordinary extension cords by overloading it with multiple devices and appliances and using it for extended periods of time. Extension cords are designed for temporary use only and its continued use and overloading is a fire hazard. Loose connections create heat and arcing which ignites nearby combustible materials. Heavy reliance on extension cords means there are too few outlets and circuits for the user’s electrical energy needs and thus the electrical system needs to be upgraded by a licensed electrical practitioner. Fires that are the foremost concern of electrical engineers are those involving design, manufacture, installation and maintenance of electrical equipment. There are four groups of causes of electrical fires: 1.Overloads 2.Insulation Failures 3.Contact Failures 4.Conductor Fractures OVERLOADS Overloading of electrical equipment and devices are usually due to
defects in installation, unauthorized expansion of electrical installation and electrical loads or inappropriate rating of wires, cables, motors and transformers. Overloading results in excessive currents that develop heat which is proportional to the square of the current (I2R). With a protection system of the right fuses or circuit breakers, overloaded circuits are easily isolated for safety. If not, the heat generated damages the insulation materials and their insulating properties. This failure of insulation leads to short circuits and the development of sparks or arcs. The operation of the protection system should quickly isolate, in a fraction of a second, the short circuit before surrounding combustible materials are ignited. INSULATION FAILURE Failure of insulation may result from deterioration due to normal aging process, thermal degradation, moisture, voltage stress, abrasion due to improper mechanical protection, mechanical vibration, environmental effects, rodent attack, some defect in manufacture, installation, utilization and maintenance of the components of the electrical installation. It results in short circuits and continuous arcing, followed by ignition of the insulating materials and the surrounding combustible materials. Many incidents of insulation failures have occurred in large installations but it does not necessarily result in fire. The fire is prevented if the arc is extinguished within a fraction of a second by the desired operation of the protection system. Short circuit incidents are to be expected but fires are not.
2nd QUARTER 2011 THE ELECTRICAL ENGINEER

During maintenance or for new installations, insulation is measured and evaluated by an insulation tester for its ohmic value and its capacitive condition through Polarization Index. Other more sophisticated tests used by electric utilities and industrial installations are Dissipation Factor and Power Factor testing. It must be noted that many fires are described in the press as caused by “faulty electrical wiring” or “electrical short circuit”. In actuality, they may refer to overloading or to failure of insulation, coupled with a protection system that does not work. CONTACT FAILURE If the connection between various components of the installation is not mechanically tight according to what is specified by the manufacturer, the contact resistance would be high. High resistance would mean heat is generated. The contact and the surrounding insulating material then starts to deteriorate and progress into failure. Deterioration and failure may take months or years to develop before it causes the problem of localized heating called hot spots. In time, as a result of progressive formation of metal oxide layers at the junction, the hot spot temperature would continue to increase and could even glow and ignite nearby combustible materials. Hot spots in the early stages are very difficult to notice and cannot be detected by the protection system. It can however be identified by heat scanners or infrared cameras. In the absence of a heat scanner, the maintenance crew should periodically tighten the contacts and look for tell-tale signs of overheating such as charring and discoloration during maintenance work. In the case of transformers, contact problems in connectors and terminals inside the tank would remain undetected by heat scanners. Dissolved Gas Analysis of oil samples may be able to detect high levels of
34
specific dissolved gases in oil formed during heating thus giving indications to maintenance personnel of heating problems inside the tank and the need to frequently monitor the transformer. CONDUCTOR FRACTURE Fracture of current conducting components are due to stresses from excessive vibration, flexing of wires and connectors, thermal stresses due to alternate heating and cooling, sharp bends, stress due to defective crimps and sub-standard or unsuitable materials used. The failure starts with metal fatigue, crack formation, crack propagation and finally fracture. It then results in local arcing at the point of fracture which may last for some time. Combustible materials nearby can then be ignited. The protection system of fuses and circuit breakers will not be able to provide protection for this type of problem. PROTECTION SYSTEM Safety is the primary concern of the protection system. It consists of devices such as fuses, circuit breakers and, in systems of higher voltages, protective relays and its associated instrument transformers. Fuses and circuit breakers should desirably isolate a circuit if there is an abnormally high current such as an over-current during short circuits or the differential protection relay of a transformer should detect short
circuits and initiate tripping of circuit breakers when there is a difference in the IN/OUT currents due to a fault in the protected zone. Protection relays used in industrial plants include over-current relays, ground over-current relays, differential protection, restricted earth fault and over-voltage relays. The protection system for commercial and industrial installations should be tested and calibrated regularly so that it will work correctly when its function is called for. ELECTRICAL CODE Electrical codes in various countries and states such as the Philippine Electrical Code (PEC) provide a basis for wiring rules. Article 1 of the PEC states that the purpose of the code is the practical safeguarding of persons and property from hazards arising from the use of electricity. It contains provisions that are considered minimum requirements necessary for safety. Compliance and proper maintenance will result in an installation that is especially free from hazard.

displayed the voltage waveform. The display showed that the waveform (simulated in Fig.1) was severely clipped at the top—making it more like a square wave than a sine wave. The peak value measured only 135V, rather than the expected 162V. The contractor then drew a one-line diagram of the system. The oneline showed that the transformer supplying the test area was at the opposite end of the building—almost 500 feet away (see Fig. 2). The majority of the loads on that transformer were non-linear, and they were drawing high peak currents at the peak of the voltage. The combination of high peak currents and high impedance of the long run combined to produce severe voltage clipping at the end of the circuit—right where the test area was.
machine went out of regulation. This is what caused the machine to reset. Solution The problem of voltage peak clipping (flat-topping) is common in high-tech buildings. Many of the buildings now in use were not designed to handle the vast array of computers and non-linear loads so typical today. In this case, extensive rewiring would be necessary to reduce the voltage drop between the transformer and the load. An alternative would be to move the most sensitive loads closer to the transformer.
Theory and Analysis Since the medical machine’s internal circuits operated on low voltage dc, the internal power supply would have a diode/capacitor input circuit that required a certain minimum peak voltage for proper operation. The nameplate on the medical machine showed the machine needed a supply voltage between 100 and 135V RMS ac. The engineers who designed the machine and specified the nameplate assumed the supply voltage would be a sine wave, so the minimum peak would be 141V peak (100 X 1.41). Since the measured value of the peak input voltage was only 135V, the machine was running on a peak voltage that was already 6V below the absolute minimum required. When the fan was turned on, the surge current drawn by the fan motor further reduced the voltage to a point where the power supply of the

Power Quality Case Study: TWO CASES OF GROUNDING PROBLEMS Dean A. S. Sempio Corporate Business Group – Technical Services MERALCO, Philippines Email: corpbus.techs.staff@meralco.com.ph Correction of Grounding Systems Eliminated Nuisance Tripping, Equipment Failures and Shock hazards
equipment. The factory has even installed UPS (uninterruptible power supply) units for reliability and to protect the computers mounted on the equipment.
Introduction The proliferation of computers and electronics are changing the way people look at power supplies and grounding. Factories now use computer controlled equipment to be more productive and efficient; and still have excellent quality control over their products. Many factories that use computers are now aware of problems that come with the use of computers – their production became more sensitive to the characteristics of power and to grounding. In the past, grounding is only associated with safety. The use of computers and other sensitive equipment is changing the way people look at proper grounding methods and practices. Case 1: Computer Production Equipment
Controlled
A factory has upgraded their equipment by installing computer based controls. The computers are ordinary desktop computers that have an interface with the production
In spite of that, the factory still experiences frequent breakdown of their computer’s hard disk drives – the hard drives that are supposed to last for at least 2 years are being replaced in just a matter of months. The effects of the breakdowns of the hard drives are not that superficial – there is also the loss of production time when the lost programs had to be re-installed in the hard drives. Power Quality Study The Power Quality engineers interviewed the actual users of the equipment and conducted site inspection. They noted the absence of a facility equipment grounding system. Although the factory transformer was grounded
(system grounding), there were no equipment grounding conductors for the production equipment. The production equipment was “grounded” by connecting wires to the nearest metal conductor in the area. A simple representation of the factory “grounding” is shown: Ground Potential Rise (GPR) during transient conditions and the unstable ground potential of the equipment reference ground were the suspected causes of the frequent breakdown of the hard drives. This is due to the equipment “grounding” that is not referenced to the main power supply – A low impedance reference to ground or functional ground of the equipment. Solution The factory decided to install an equipment grounding system that is referenced / connected to the main transformer grounding. The purpose is to have all the “grounds” attain the same potential; when “grounds” of circuits supplied by a particular source have practically zero potential difference with respect to each other then the circuit, control and logic voltages will be stable; ground loops will be eliminated. All of the factory’s production equipment is now connected to equipment grounding that is part of the system grounding. Under the new grounding

Technical Feature setup, the number of incidences of hard disk breakdowns has dropped dramatically. In fact, no hard disks were replaced in the succeeding three years after the new grounding system was installed.
A power quality monitoring equipment was installed at the panel serving one of the production equipment suffering from “nuisance tripping”. The following data was recorded:
equipment as well as the incidence of workers getting electric shocks have virtually disappeared.
The line to ground voltage increased dramatically in one of the circuit conductors that what was later found out to be a fault inside a production equipment. This is also the reason why the equipment body becomes energized. Despite the rise in voltage, no protective devices were activated.
CONCLUSION People are now becoming aware of proper grounding practices with the application of electronics and computers in production equipment. As shown in the case studies, plants need to improve the grounding of their electrical system as they upgrade and automate their production equipment. Proper grounding is no longer just about safety, it is also essential to the proper and continuous operation of sensitive electronic based equipment.
Case 2: Neutral to Ground Voltage A factory is experiencing abnormal line to ground voltages. These abnormal voltages are being blamed for “nuisance tripping” of some production equipment. In some instances, the machine operators get shocked when they come in contact with some parts of their machines or on some metal outcroppings near their equipment. The incidents happen only in certain places within the factory. Power Quality Study The Power Quality engineers interviewed the production workers that come into contact with the equipment that suffer from “nuisance tripping”; they also conducted site inspection. The factory transformer was also checked and it was found out that there was no equipment grounding conductor coming from the transformer. The production equipment “grounding” consists of a wire connected to a panel box embedded in cement.

Solution The absence of proper grounding from the transformer to the equipment explains how the ground voltage “floats” to abnormal levels without tripping the protective devices. Faults in the electrical system can continuously energize equipment if there is no effective grounding that is referenced to the transformer secondary. The factory installed an equipment grounding system referenced / connected to the grounded neutral of the transformer secondary. The “nuisance tripping” of production
