knock-off luxury goods, bootleg moviesand music trading. Without proper aware-ness of the repercussions and potentialhazards of counterfeit safety-related prod-ucts, many consumers are attracted bytheir low prices.Counterfeit electrical products can have

a significant negative impact on manypeople. These knock offs are unable tomeet even minimum quality specificationsand fail to perform even the most basicrequirements for electrical circuit protec-tion. Instead, these sub-standard, unsafeproducts often overheat or cause short cir-cuits, leading to fires, shocks or failuresthat can cost people considerable propertydamage or even their lives.

Counterfeiting has been a growingproblem worldwide for more than adecade and has increased by 10,000 per-cent over the past 20 years. In 2009, U.S.Customs and Border Protection (CBP) re-ported that electrical products repre-

I recently gave a keynoteaddress at the Certification IndustryAgainst Counterfeiting (CIAC) NorthAmerican Summit in Arlington, Va. Itwas an enlightening conference thatbrought together the certification indus-try, the Department of Homeland Secu-rity, Interpol, brand holders, and industryexperts to discuss the health and safetyrisks that counterfeit products pose. Op-portunities like these, where minds cancome together in one room and share is-sues, solutions and collaborate on futureendeavors, are vital to the successful fightagainst counterfeiting. Every solution pre-sented, by individuals and industry expertsalike, made one thing clear: we cannot ad-dress issues like counterfeiting without awell coordinated collaboration of govern-ment, law enforcement, and industry.There were many bright minds who

presented on the issues of counterfeiting.The case studies, panel discussions, andexpert presentations all confirm that coun-terfeiting is prevalent in many industries.While the most frequently seized counter- Continued on page 8

are equally spaced. (See Figure 21)In multiple electrode systems, the 62%

method electrode spacing may nolongerbe applied directly. The distance of theauxiliary electrodes is now based on themaximum grid distance (i.e. In a square,the diagonal; in a line, the total length. Forexample, a square having a side of 20 ftwill have a diagonal of approximately 28ft). Three readings, minimum, are still re-quired for proper testing.

Tech Tips Excessive NoiseExcessive noise may interfere with test-

ing because of the long leads used to per-form a Fall-of-Potential test. A voltmetercan be utilized to identify this problem.Connect the “X”, “Y” and “Z” cables tothe auxiliary electrodes as for a standardground resistance test. Use the voltmeterto test the voltage across terminals “X”and “Z”. (See Figure 25)The voltage reading should be within

stray voltage tolerances acceptable to yourground tester. If the voltage exceeds thisvalue, try the following techniques:A) Braid the auxiliary cables together.

This often has the effect of cancelingout the common mode voltagesbetween these two conductors.(See Figure 26)

B) If the previous method fails, trychanging the alignment of the auxil-iary cables so that they are not paral-lel to power lines above or below theground. (See Figure 27)

C) If a satisfactory low voltage value is

Multiple Rod SpacingParallel multiple electrodes yield lower

resistance to ground than a single elec-trode. High-capacity installations requirelow grounding resistance. Multiple rodsare used to provide this resistance.A second rod does not provide a total

resistance of half that of a single rod un-less the two are several rod lengths apart.To achieve the grounding resistance, placemultiple rods one rod length apart in aline, circle, hollow triangle, or square. Theequivalent resistance can be calculated bydividing by the number of rods and multi-plying by the factor X (See Figure 20).Additional considerations regarding stepand touch potentials should be addressedby the geometry.Placing additional rods within the pe-

riphery of a shape will not reduce thegrounding resistance below that of the pe-ripheral rods alone.

Multiple Electrode SystemsA single driven grounding electrode

is an economical and simple means ofmaking a good ground system. Butsometimes a single rod will not providesufficient low resistance, and severalgrounding electrodes will be driven andconnected in parallel by a cable. Veryoften when two, three or four groundingelectrodes are being used, they are dri-ven in a straight line; when four or moreare being used, a hollow square configu-ration is used and the grounding elec-trodes are still connected in parallel and

still not obtained, the use of shieldedcables may be required. The shieldacts to protect the inner conductor bycapturing the voltage and draining itto ground. (See Figure 28)

Therefore, E/I = Rx is established. If Iis detected with E kept constant, mea-sured grounding point resistance can beobtained. Refer again to Figures 31 and32. Current is fed to a special trans-former via a power amplifier from a2.4kHz constant voltage oscillator. Thiscurrent is detected by a detection CT.Only the 2.4kHz signal frequency is am-plified by a filter amplifier. This occursbefore the A/D conversion and after syn-chronous rectification. It is then dis-played on the LCD. The filter amplifieris used to cut off both earth current at

commercial frequency and high-fre-quency noise. Voltage is detected by coils wound around the injection CTwhich is then amplified, rectified, andcompared by a level comparator. If theclamp is not closed properly, an “openjaw” annunciator appears on the LCD.

Examples: Typical In-FieldMeasurementsPole Mounted TransformerRemove any molding covering the

ground conductor, and provide sufficientroom for the Model 3711 & 3731 jaws,which must be able to close easily aroundthe conductor. The jaws can be placedaround the ground rod itself.

Note: The clamp must be placed so thatthe jaws are in an electrical path from thesystem neutral or ground wire to theground rod or rods as the circuit provides.

Select the current range “A.” Clamponto the ground conductor and measurethe ground current. The maximum currentrange is 30A. If the ground current ex-ceeds 5A, ground resistance measure-ments are not possible.Do not proceed further with the mea-

surement. Instead, remove the clamp-ontester from the circuit, noting the locationfor maintenance, and continue to the nexttest location.After noting the ground current, select

the ground resistance range “Ω” and mea-sure the resistance directly. The readingyou measure with the Model 3711 & 3731indicates the resistance not just of the rod,but also of the connection to the systemneutral and all bonding connections be-tween the neutral and the rod.Note that in Figure 33 there is both a

butt plate and a ground rod. In this typeof circuit, the instrument must be placedabove the bond so that both grounds areincluded in the test. For future referencenote the date, ohms reading, current read-ing and point number. Replace any mold-ing you may have removed from theconductor.

Note: A high reading indicates one ormore of the following:A) Poor ground rodB) Open ground conductorC) High resistance bonds on the rod or

splices on the conductor; watch for buriedsplit bolts, clamps and hammer-on con-nections.

Clamp-On Ground ResistanceMeasurementThis measurement method is innova-

tive and quite unique. It offers the abilityto measure the resistance without discon-necting the ground. This type of measure-ment also offers the advantage ofincluding the bonding to ground and theoverall grounding connection resistances.This method requires connection of utilityneutral or another grounding system sothat the signal goes out to the other sys-tem and returns to the test point throughthe earth.

Principle of OperationUsually, a common distribution line

grounded system can be simulated as asimple basic circuit as shown in Figure 32or an equivalent circuit, shown in Figure33. If voltage E is applied to any mea-sured grounding point Rx through a spe-cial transformer, current I flows throughthe circuit, thereby establishing the fol-lowing equation.

Service Entrance or MeterFollow basically the same procedure as

in the first example. Notice that Figure 34shows the possibility of multiple groundrods, and in Figure 35 the ground rods havebeen replaced with a water pipe ground.You may also have both types acting as aground. In these cases, it is necessary tomake the measurements between the ser-vice neutral and both grounded points.

Pad Mounted TransformerNote: Never open transformer enclosures.

They are the property of the electrical utility.This test is for high voltage experts only.Observe all safety requirements, since

dangerously high voltage is present.Locate and number all rods (usually only

a single rod is present). If the ground rodsare inside the enclosure, refer to Figure 36and if they are outside the enclosure, refer toFigure 37. If a single rod is found withinthe enclosure, the measurement should betaken on the conductor just before the bondon the ground rod. Often, more than oneground conductor is tied to this clamp, loop-ing back to the enclosure or neutral.In many cases, the best reading can be

obtained by clamping the Models 3711 &3731 onto the ground rod itself, below thepoint when the ground conductors are at-tached to the rod, so that you are measuring

the ground circuit. Care must be taken tofind a conductor with only one return pathto the neutral.Both the fall-of-potential and the clamp-

on test method can be effectively used tomeasure a grounding electrode system byjust observing a few simple rules. Groundresistance testing can be quick and easy andcompleted with the confidence that the testhas been conducted properly by followingthe steps outlined here. Also modern dayinstruments can take all of the guess workout of testing and provide the ability to printout professional reports.

Making Sense of the Complicated CAT5/6 CableInstalling network devices (VoIP phones, IP cameras, access

points) always had 2 steps: 1) Plug in the network cable and 2)shove the power plug into an AC outlet. That’s changed nowthat many devices are powered from the network cable using amethod defined as Power over Ethernet (“PoE” for short). Thischange has caused frustration and confusion during the installprocess… not knowing whether power or a data path is avail-able…. and no way to find out because the measurementprocess is complicated. Plus, most VoIP and IP camera installersare experts in the fields of phones and security… not networks.The Power Panel CAT5/6 DVM is the right tool at the right time

because, once connected, it goes to work scanning each pin onthe connector and displaying both activity and pair location. Whether it be network devices, phones or PoE,the installer has the information he/she needs for a successful and quick installation.

Cable SupportsThe BNT family of cable supports from Underground Devices meets

power utility needs for a manhole cable support system that is non-metallic and nonconductive. These cable supports are an ideal re-placement to steel cable racks since they will not rust or corrode,eliminate the need for grounding the cable supports andmake theuse of insulators unnecessary. Additionally, BNT arms and stanchionshave loading capacities comparable to similar heavy duty steelcable racks. Arm installation is safe and simple for the BNT family ofcable supports. The arms are secured in placewith nonmetallic pins,allowing for installation and removal of the arms without disturbingany cable. The BNT arms also mate with many existing steel stan-chions, allowing for a gradual retrofit of existing manholes.Due to the extreme strength and rigidity of the BNT stanchions,

most installations require only two bolts to secure a stanchion to themanhole wall.

Schneider Electric Xantrex™ XW MPPT 80 600Solar Charge ControllerThe MPPT80 600A is an innovative solar charge controller from Schneider Electric. The

product accepts PV array voltages up to 600 volts and converts to 24V or 48V batterycharging voltage. Traditional solar charge controllers typically offer input voltages up to200V. By making the jump to 600V input, wire gauges and conduit sizes are dramatically re-duced; minimizing installation costs. In off-grid applications, the use of high voltage inputallows customers to site a PV array hundreds of feet away from the controller; opening upmore installation possibilities. Installers can deploy clean PV string configurations typicallyused in grid-tie applications now in battery-based systems.The MPPT80 600 features on-board data-logging, PV ground fault protection, and can be

used in positive, negative, and ungrounded arrays. The unit uses Schneider’s XANBUScommunications protocol to allow the daisy-chaining of multiple controllers, andseamless integration into a Schneider Electric XantrexTM XW Inverter/Charger System.

Selecting the RightSolar Mounting System

Understanding landscape versus portrait solar panel orientation optionsBy Tim Fox, Solar Market Manager, Cooper B-Line

FEATURE • Cooper B Line


(D) and (H) are described in Figure 2 on the next page.As is apparent in the calculation of (D), the row spacing is

dependent on the height of the panel and the degree of tilt.Therefore, to correctly calculate which orientation will optimizeefficiency, both landscape and portrait orientations must be eval-uated to determine the relationship that the panel height (H) hason the number of panels that can fit into a given area.

To do this, it is appropriate to determine the maximum num-ber of panels (n) that can fit into a given area (A) in both land-scape and portrait orientation. The end result is equivalentequations for both landscape and portrait layouts, where whichshows no correlation between the number of panels in a givenspace and the orientation of the panel.

In summary, panels can be oriented in the landscape or por-trait orientation with virtually no affect on the quantity of panelsthat can be installed. Therefore, there is no difference on arrayefficiency over a given rooftop space or given ground space.Due to this fact, efficiency optimization decisions should bebased on optimizing panel efficiency and rack-

Maximizing the efficiency of solar panel installa-tion hinges on the ability to install as many panels as possible ina given area. Often, the question of whether to install the panelsin landscape or portrait orientation arises, and common thoughtsuggests that choosing one orientation over the other will lead tothe ability to install more panels over a given footprint.

Landscape Versus PortraitThere are two primary issues that result in the debate between

which orientation is optimal. The first issue is the number ofpanels that can be installed in a given length. Figure 1 showsthe layout for a given row length and the difference in the num-ber of panels that will fit and may be installed.

It is possible to fit more portrait panels within a given rowlength. This leads to the second issue of how many panels can beinstalled within a given height. The primary consideration inanswering this is the amount of shading provided by a givenrow. The shading distance is the minimum distance allowed be-tween rows; thus dictating minimum row spacing and ultimatelythe total number of rows available over a given space. To cal-culate shading distance, and therefore row spacing, the SolarEnergy Handbook suggests using the equation

D=Sin (α +Θ) * as a method to determine the distance from thefront edge of a panel in one row to the front edge of a panel in thenext row. The variable (Θ) is the tilt of the panels while the variable(α) is a function of the latitude of the installation and the optimalsun elevation. The sun elevation (α) can be found from a sun chartsimilar to the one published by the University of Oregon at:http://solardat.uoregon.edu/SunChartProgram.php. The variables

ing systems rather than on the number of panels dictated by aparticular orientation.

Selecting a Mounting SystemThe new ARISTA™ Mounting System from Cooper B-Line,

for example, is flexible enough that it can accommodate eitherlandscape or portrait orientations. Key factors to consider are ba-

sic wind speeds, roof structure and other project variables to de-termine the type of mounting required for each particular system.There are also ballasted and positively tied options available toprovide added flexibility, while the system’s hinged design allowsfor rooftop maintenance without having to disconnect panels.

The primary benefit of this new system is time and labor sav-ings since there are so few parts to install. But, in addition, it isan environmentally responsible choice, with the use of recycledmaterials, such as the ARISTA™ system’s DURA-BLOK™supports which are made of 100 percent recycled rubber. Thismakes them eligible for Leadership in Energy and Environ-mental Design (LEED®) credits

The City of East Cleveland is decreas-ing energy costs by replacing 45 standard-technology municipal street lights withGE’s award-winning Evolve™ LED road-way street lights. The project grows outof a long partnership between GE Light-ing and East Cleveland, which has beenthe home of the unit’s headquarters forclose to 100 years. A one-mile blockalong Noble Road serves as a demonstra-tion to other municipalities of the benefitsof a higher-efficiency lighting system.

The U.S. Department of Energy’s na-tional laboratories predicts that LED lightsreduce energy needs by more than 50 per-cent and maintenance costs by more than80 percent compared to traditional lights.It’s estimated that the new GE Evolve

LED street lights will reduce the city’s en-ergy use by 28 million watts a year.

“For nearly a century, GE Lighting hashad a powerful, positive impact on ourcommunity and on northeast Ohio, in gen-eral,” said Mayor Gary Norton, Jr. “We’reelated to be among the first cities in theCleveland region to work with GE to haveits new LED street lighting system inplace. This installation allows East Cleve-land to set the standard for other commu-nities seeking economical,energy-efficient municipal lighting.”

Mayor Norton said that the GE LEDstreet lights give city residents the en-hanced security associated with this high-performance lighting system. The systemshines a bright, more uniform light across

the entire area it illuminates, versusspotty, hot spots of light typical of certainother lighting technologies used in road-way lighting. Even with less lumens, orlight level, compared to a high-intensitydischarge street lighting system, the LEDsystem better directs the light to where itis needed due to its advanced optics. TheGE LED street lighting system is moreprecisely focused, which reduces lightpollution and limits glare.

“Our new GE Evolve LED street lightsare the perfect fit for the needs of urbanmunicipalities,” said Michael B. Petras,Jr., President & CEO of GE Lighting.“With this project, East Cleveland is de-ploying aesthetically-pleasing, high-tech-nology street lights that offer excellent
