Current Measurement Methods that Deliver High Precision Power Analysis in the Field of Power Electronics
By Hajime Yoda, Assistant Chief Engineer, Hiroki Kobayashi, Assistant Chief Engineer and Shinya Takiguchi, Senior Staff, Hioki E.E. Corporation
1. INTRODUCTION Various power electronics applications demand high-precision power (current and voltage) measurement of such characteristics as the power conversion efficiency of power conditioners, the efficiency of inverters and motors, and reactor losses. This study examines the use of current sensors with power meters as an alternative to the direct connection especially for measuring higher currents and the need to evaluate measuring instruments not for their individual performance characteristics but the combination of equipment as a power measurement system to answer high accuracy and high precision demands.

The measurement principle For example, concerning the effect deitself is extremely simple, with the advan- scribed in ii) above, a tage of enabling a power analyzer to be used to measure current on a standalone basis, making it the de facto method for many years. However, since the current wires must be routed over a long distance and the current input portion of the power analyzer must be inserted into the measured object’s circuit, the following disadvantages exist: i) Conditions differ from those that characterize actual operation

5-meter run using No. 6 AWG wire would have a wire resistance of approximately 6.5 mW. If the current under measurement were 30 A, the loss resulting from this wiring resistance would be 5.85 W. Although it is impossible to make any judgment concerning the magnitude of the loss based solely on this value, it would be too large to ignore for some measured power values. In addition, when using the direct connection method, current usually is measured by means of a shunt resistance. This shunt resistance method suffers from the following disadvantages: i) When current flows into the shunt resistance, Joule heat proportional to the square of the current occurs in the resistance. As long as the Joule heat contributes to instrument loss, the selfheating will change the resistance value of the shunt resistance itself, which will further worsen the measurement accuracy. ii) To limit this heating, a shunt resistance with a low resistance value is used. However, when a small shunt resistance is used to measure a large current, even slight inductive components cannot be ignored, which degrades the frequency charContinued on page 8 acteristics.

sor with a rating of 50 A has been connected to the circuit. You can see that the temperature of the shunt resistance rises to about 50°C due to self-heating caused by Joule heat. By contrast, the current sensor is mostly unaffected by Joule heat and associated self-heating, and instrument loss and effects of the sensor’s own temperature characteristics on measurement precision are negligible. As demonstrated by the above discussion, the direct connection method is well suited for the measurement of very small currents of about 1 A where the effects of the shunt resistance’s Joule heat are sufficiently small, for example measurement of the standby power of electronic devices or measurement of the power consumption of LED lighting.

and the output signal (current or voltage) from the sensor is input into the power analyzer. The current sensor method can be used to measure a target in its operating state, and the almost complete lack of self-heating when measuring large currents means that there is no effect on measurement accuracy. The current sensor method is better than the direct connection method at measuring large currents of about 5 A or greater with a high degree of precision, and it is generally used in the power electronics field. Fig. 3 illustrates the approximate range of current values that can be measured with a high degree of precision and the associated general frequency band for both the direct connection method and the current sensor method.

3. HIGH-PRECISION POWER MEASUREMENT USING THE CURRENT SENSOR METHOD As described above, it is typical to use the current sensor method when measuring currents in excess of 5 A. While the current sensor method does not suffer from the same disadvantages as the direct connection method, there are nonetheless a number of precautions that must be borne in mind in order to measure current at a high level of precision. This section outlines those precautions.

Furthermore, the following considerations should be borne in mind: iii) The current sensor must provide a sufficient level of measurement accuracy that is defined across the entire measurable frequency band. iv) All error factors, for example output noise, temperature characteristics, conductor position effects, external magnetic field effects, magnetization effects, and common-mode voltage effects for the current sensor, must be defined and sufficiently small in magnitude. A sufficient level of caution is required when selecting a current sensor. In particular, concerning consideration iii), amplitude and phase accuracy for most current output sensors are only defined for DC and 50/60 Hz frequencies, and accuracy for other frequency ranges is provided only for reference purposes only. It is important to note that high-precision current measurement using the current sensor method hinges on the availability of both current sensors and a power analyzer with an adequate level of performance. ❏
High-precision, highly reproducible power measurement using the current sensor method presumes selection of a suitable current sensor. Specific selection criteria include the following two considerations: i) The current sensor’s rated current value must be appropriate for the magnitude of current to be measured. ii) All frequency components of the current to be measured must fall Part 2 of this article will be published in within the current sensor’s measurthe August issue of Electrical Products able frequency band. & Solutions magazine.

Safety Center Tower Grounding Professionally Installed and Maintained Lightning Protection and Grounding Systems Ensure Uptime and Reduce County’s Costly Repairs By Victoria Wolber and Greg Fair
Municipal safety centers typically combine police, fire, 9-1-1 and other emergency services – they must remain operational at all times. If communications systems fail, dispatchers are helpless, emergency workers can’t find each other and the public could be at risk. Victoria Wolber is the director of emergency management and communications for Macomb County, Michigan. She is based at COMTEC, the county’s impressively rebuilt, 25,000 square feet safety center in Mt. Clemens, Michigan in the southeastern part of the state, (Cover). “It’s critical that our communications services remain up and running because we’re often dealing with life-and-death situations in our 9-1-1 dispatch center, and we have to get our personnel to the injured as fast as possible,” said Wolber. All communications systems need antenna towers, which naturally invite lightning strikes that can cause damage to a center’s sensitive equipment. The solution: equip the towers with robust, correctly de14
signed and properly installed lightning protection and grounding systems to direct lightning energy away from sensitive equipment and harmlessly into the earth before it damages equipment. “We knew that we had to call in experts who understood the lightning protection and grounding fields, knew our systems and knew what to do to protect our critical assets,” said Wolber. “We did that, and we’ve never had any lightning-caused downtime here at COMTEC.” Wolber and her electrical contractor hired Greg Fair, a project manager and field superintendent with Guardian Equipment Company, a Michigan-based firm that specializes in lightning protection. Since COMTEC was relocating to an existing structure with a pre-existing tower, the challenge was to formulate a system that met the applicable codes and accommodate the site’s components. During re-construction, the building’s open walls helped Guardian Equipment advised the engineers on designing and con-

aging. They were mechanical, in one case using a simple water pipe connector, and they had become loose over time. There was also some corrosion, which increases ground resistance (Figure 2). To aid in the new grounding system design, Fair and his team referenced several codes that dealt specifically with grounding for lightning protection: Underwriters Laboratories’ UL96A: Installation Requirements for Lightning Protection Systems,” the National Fire Protection Association’s NFPA 780: Standard for the Installation of Lightning Protection Systems, NFPA 780 and the Lightning Protection Institute’s LPI 175: Standard for the Design – Installation – Inspection of Lightning Protection Systems. The well-known and often used Motorola 56A, which also deals with towers, did not fall within the scope of work. Fair and his team began with a site survey to guide their engineers in designing the work. Following the survey, the team installed air terminals (also called lightning

Grounding of the center’s water and gas service entrances is provided by the heavy-gage copper cable, right. The tag shown on the left alerts technicians that grounding to gas and other services is code-mandated.
When lightning strikes one of the nine auxiliary sites that the county operates, energy is bled off the coax on the vertical run (Fig. 7), the coax where it penetrates the firewall and the interior side of the firewall.
“On the two-story side of the structure, which is less than 75 feet tall, we used 29strand x 17-Gage Class I wire. It’s a little thinner and less obtrusive to the eye,” said Fair (Figure 3). All services, such as electric, water and gas were bonded together at a common ground potential and bonded to the building’s grounding system, in accordance with code requirements (Figures 4a and 4b). Fair tags his installations where appropriate to inform workers of the Code-sensitivity of those connections. “We also bonded to exposed building steel,” said Fair. “There are people who believe that using building steel is not advisable because it can lead to side flashes since the entire structure becomes energized when a strike hits. But it won’t do that if the building is properly grounded and if the sizes of the conductors are ade-
quate to provide the path the lightning current preferentially follows, i.e. through the path of lowest resistance and/or impedance (emphasis by Fair). We provide that path.” Bonding the grounding system to building steel is also a code-mandatory practice. However, while building steel might provide a de facto ground/earth connection, a continuous electrical path cannot always be verified and grounding connections should properly be made via adequately sized copper down-conductors bonded to appropriately spaced, driven electrodes. A rooftop level ring-ground surrounding the structure might also be employed, as was done at the COMTEC facility. The ring simplified installation of the lightning protection/ grounding system, and its copper downconductors, blended in well with the center’s brick walls. ❏

One of several auxiliary transmission towers operated by Macomb County. The towers extend emergency communications well beyond the range of the COMTEC headquarters tower. All towers are equipped with the same highquality, all-copper grounding systems as those installed at COMTEC.
A copper grounding bar is mounted on the tower approximately 10 feet above grade. The six smalldiameter cables leading upward from the bar connect to shields on cables and/or waveguides leading down from antennas above. The two heavy grounding cables leading downward from the bar are the down-conductors shown in Figure 9.

below. Approximately 15 driven electrodes were spaced about 100 feet apart surrounding the structure. Two of them specifically bonded to the ring-ground surrounding the tower. “We grounded the tower with 28R cable, which is a special Class II lightning conductor consisting of 28 strands of bare, braided AWG 14-Gage wire,” said Fair. “We sometimes use tinned wire when our engineer of record thinks that it would give the conductor a longer service life, but that wasn’t the case here.” Class II cable is used for structures taller than 75 feet. It is also good when conductors have to be exothermically welded to ground rods, building steel, or in this case, to the tower itself. 18

Celebrating Autac’s 70th Anniversary AUTAC INC. HOSTED an Open House/Re-launch Party on June 16, 2016 from 1pm-4pm at their Branford location. The event was to celebrate 70 years in business and the launch of their new website and catalogue. “Technically Autac was founded in 1945 and incorporated in 1947. All the literature over the years has paid homage to the incorporation date or I guess the day when Dad moved the company out of his garage to an actual place of business in 1947” laughs the CEO, Marie-Louise Burkle. “Since we launched our new website and catalogues this year I just figured why not split the baby and make 2016 the 70th Anniversary? Plus we had so much to celebrate. The company has been doing really well the last year. And to finally be healthy enough to return to run-
ning Autac is something I’m personally celebrating! It was a rough run from 2010-2015. My illness, the collapse of our company headquarters in the Blizzard of 2011 and of course the economic issues specific to manufacturing in Connecticut; it’s a miracle we survived. 2015 was a real turning point for me and for Autac. It was time to recognize this fresh start and revel in a new life for Autac and myself.” The event will began at 1pm. The plant was running live for tours from 1-2:30 but the facility had an open house from 1-4. Also from 1pm-4pm Autac had food trucks, music, libations, games and extensive networking opportunities.

industry NEWS “It was our goal to create a Museum that the local Staten Island community deserved. Our commitment to being a good community partner was an important element in how we approached our expansion and the building’s lighting,” said Cheryl Adolph, President & CEO, Staten Island Museum. “The difference the Soraa LED lamps brought to the galleries and our exhibits is substantial – both in quality of lighting and energy efficiency.” Working with the Museum staff and exhibition designers Ralph Appelbaum Associates, lighting designer Kyle Chepulis and the design team of Technical Artistry installed approximately 400 Soraa PAR30 LED lamps as part of the goal to achieve LEED Gold status while perfectly illuminating the Museum’s world-class exhibits. “Our goal was to find the right lighting solution to illuminate these colorful pieces amidst the abundant natural daylight and with the right color temperature. Soraa LED lamps help to create a mood that enhances the patron experience, allowing them to connect to the images,” said Chepulis.
Technical Artistry worked with Litelab Corporation to make a custom track fixture (now part of their standard line) with a classic cylinder shape that worked with Soraa LED lamp. Soraa was the perfect solution for the unique galleries and application. That’s because Soraa’s GaN on GaNTM LED with Violet-Emission 3-Phosphor (VP ) LED technology renders the widest range of colors in the objects that we see, without ultraviolet (UV) or infrared (IR) radiation that can fade or harm the artifacts. Soraa’s unique GaN on GaN™ technology allows its LEDs to operate at currents that are more than five times higher than LEDs built on other materials. This means a lot of light comes from a very small source, resulting in a narrow beam that can be controlled to crisply illuminate any area with a single shadow. The masterful art works presented in the Staten Island Museum are illuminated for perfect rendering of colors and whiteness because of Soraa’s Violet-Emission 3-Phosphor (VP ) LED technology. Utilizing every color in the rainbow, especially deep red emission, Soraa’s lamps render warm tones beautifully

new PRODUCTS DEWALT® Unveils FLEXVOLT™ System Power of Corded. Freedom of Cordless.™ DEWALT unveils the FLEXVOLT™ system, which features the world’s first batteries that automatically change voltage when the user changes tools. Two FLEXVOLT™ batteries, a 6.0Ah battery (DCB606) available in the fall of 2016 and a 9.0Ah battery (DCB609) available in early 2017, power the lineup of brushless 60V MAX* and 120V MAX* FLEXVOLT™ tools. What makes these two FLEXVOLT™ batteries extremely innovative are their patent-pending technology that is backwards compatible with most existing DEWALT 20V MAX* tools and chargers. When used in DEWALT 20V MAX* tools, the 6.0Ah FLEXVOLT™ battery provides up to 4X runtime**. In addition, the FLEXVOLT™ battery provides more than 3X battery power versus DEWALT 18V NiCad. The key to this technology is the ability of the FLEXVOLT™ batteries to switch between DEWALT tools of varying voltages (20V MAX*, 60V MAX* and 120V MAX*). The FLEXVOLT™ batteries automatically change voltage depending on whether they’re being used in a 20V MAX* or 60V MAX* tool. Two FLEXVOLT™ batteries (of same amp hour) together power the new DEWALT 120V MAX* tools. This means that high power tool applications that previously could only be accomplished by corded tools, can now be performed with the DEWALT FLEXVOLT™ system of cordless tools. As a result of this advanced battery technology, jobsites can now fully transition from corded to the freedom of cordless. Both the 6.0Ah & 9.0Ah FLEXVOLT™ batteries will extend the runtime of existing DEWALT 20V MAX* tools, and also power five new 60V MAX* tools and two new 120V MAX* tools (with 2 FLEXVOLT™ batteries). The new 60V MAX* FLEXVOLT™ brushless tools include a 7-1/4” Circular Saw (DCS575), 4-1/2”-6” Grinder (DCG414), Reciprocating Saw (DCS388), 1/2” VSR Stud and Joist Drill (DCD460), and 8-1/4” Table Saw (DCS7485). The new 120V MAX* FLEXVOLT™ tools are a 12” Fixed Head Compound Miter Saw (DHS716) and 12” Sliding Compound Miter Saw (DHS790). For more information, visit www.dewalt.com

Additionally, the product’s self-contained electrical junction box and easily deployed lighting control system help dramatically reduce installation costs. “The All Field Series brings our experience with deploying high-output, extremely efficient LED lighting solutions at some of the most prominent professional sports venues to high school and municipal fields of all sizes,” said Mike Lorenz, president, Eaton’s Ephesus Lighting business. “Since professional and municipal field managers face different challenges, our innovative technology is designed to give these smaller venues high-quality, controllable, cost-effective and energy-efficient LED lighting.” The enhanced engineered optics of the Ephesus All Field Series efficiently delivers uniform light on the field and significantly reduces unwanted light spill and sky glow. Furthermore, the efficiency of the All Field Series allows for a dramatic reduction in fixtures versus other field lighting solutions. The Ephesus All Field 750 and 550 models offer unmatched controllability with communication technology commonly used in the Wi-Fi and cellular market. The fixtures provide two-way communication with the capability to self-monitor and report performance and wellness data from each fixture. For more information, visit www.eaton.com

new PRODUCTS Milwaukee® Introduces Performance Work Gear The industry leader in heated gear, Milwaukee Tool, has expanded its Work Gear line to include a new Jacket and cold weather Base Layer. The Milwaukee® Hooded Jacket and WorkSkin™ Base Layer’s combination of heavy duty construction and performance materials provide users all-day comfort and durability in even the toughest jobsite conditions. “Milwaukee’s popular M12™ Heated Gear provide an excellent way for users to stay warm in cold conditions utilizing REDLITHIUM™ technology; but in looking at how people use gear more broadly, it was obvious that most of the insulated workwear hasn’t changed for decades. As a result, today’s industry professionals lack effective non-battery-powered solutions that are designed for their specific needs,” said Patrick Lueck, Product Manager for Milwaukee Tool. “Our new Performance Work Gear begins to address the full scope of what our users need to do while on the job. After years of jobsite research, we’ve designed a new Hooded Jacket that reinvents the classic style by combining the very best rugged material with targeted durability reinforcements and innovative mobility enhancements that make it easy to move around in all day.” Engineered to battle the jobsite and survive the elements, Milwaukee’s Hooded Jacket is built for tradesmen who can’t let cold slow them down. Focused on providing reinforcement in areas where traditional workwear fails, its GridIron™ 900 Denier Ripstop Polyester material outlasts cotton duck by 3X against abrasion and tearing. Large riveted and reinforced utility pockets and a tarnish resistant metal zipper provide increased durability. The Jacket also features FreeFlex™ Mobility enhancements across the back, underarms and armpits, and a fitted hood designed to provide full range of vision. The combination of these features make the new Hooded Jacket perfect for users who require trusted durability while on the jobsite, and the maneuverability that helps them get the job done.
