Fall-of-Potential vs. Clamp-On Ground Resistance Testing

By John Olobri, Director of Sales and Marketing, AEMC® Instruments

H

ow do these test methods differ?

Why choose the Clamp-On method? Is the Clamp-On method as accurate as the Fallof-Potential method? I was told that I had to use the Fall-of-Potential method. Why can’t I use the Clamp-On method?

These are questions that come up on a regular basis by technicians out in the field trying to get a job done correctly and efficiently. This article will attempt to explain, in basic terms, the functions, differences, advantages and disadvantages of each testing method. We will also discuss the latest advancements in Clamp-On test instruments.

Let’s start with the Fall-of-Potential method. This test method has been in use since the very early 1900s. A Fall-of-Potential ground resistance test requires an instrument, three or four spools of wire (depending on the test to be conducted) and an equal quantity of auxiliary test rods. The principal operation is simple; a known test current at a controlled frequency, usually 128 Hz (to avoid interference with the fundamental power frequencies of 50 or 60 Hz), developed in

the instrument is injected into the earth at a point downstream from the grounding electrode or system to be tested. This is accomplished through the use of one of the auxiliary grounding rods and one of the spools of wire. This rod is referred to as the injector. Various manufacturers have different labels for this. It is referred as the Z rod or the C2 rod. The most recent international standard label for this rod is H. The test current injected at this point wants to get back to its source and does so through the connection to the ground test instrument connection at the rod or grounding system under test. This point again labeled differently by manufacturers of ground test instruments as X or Xv or C1 and P1 and now the international standard is E and ES. Finally a voltage drop (Fall-of-Potential) is measured along the path between the injector and the point of test by inserting a second auxiliary rod and wire at various points. This auxiliary rod is labeled Y or P2 and the new international labeled S. See Figure 1 for a typical test set up. Hereafter we will use the international H, S, E and ES labeling for simplicity.

Figure 1 - Fall-of-Potential system

Electrical Products & Solutions • January 2014

Note: typically E and ES are tied together at the instrument.

Knowing the injected current and measuring the voltage provides the variables needed to internally calculate the resistance using Ohms law R=E/I. The instrument divides the voltage measured between points S and E by the current injected at point H. It then calculates and displays the resistance value of the grounding electrode system under test.

Simple enough. Yes, but there are many factors to be considered to get good test results. First and foremost the distance between E and H must be great enough to prevent influence from one to the other.

Typically it is initially calculated to be eight to ten times the depth of the rod or the diagonal distance of the grid under test. This could be hundreds and even thousands of feet. Quite often this distance is not attainable for a variety of reasons not the least of which is adjacent private property. A consideration for the instrument used is the available test current when long distances are required particularly in soils with high Continued on page 8

resistivity or asphalt. The higher the test current the better. Fall-of-Potential test instruments are available with test currents of a few milliamps to several hundred milliamps.

The best way to confirm that the spacing is correct is to take measurements at 10 percent increments between points E and H. Measurements where S and E are close together will be low. As you move towards H the readings will increase in re8

sistance and will plateau at generally between 50 to 70 percent of the distance and begin to rise again as you move closer to H. If you see the plateau then you can be confident that there is no influence between the rod under test E and the injector H. If the resistance continues to rise at all points along the test then you can assume that there is interference between E and H. See Figure 2.

A true Fall-of-Potential test will require

a minimum of nine measurement points (one every 10% of the distance) between E and H. A simplified method often used to save time requires only three measurements, one at 52, 62 Continued on page 12

and 72% of the distance. This test is known as the 62% method. Using either method requires taking the three readings obtained in the plateau area and averaging them to obtain the effective grounding resistance of the test site.

Another important point to consider is that the rod or grounding system to be tested must be isolated and disconnected from other grounding systems such as building steel and the GEC (grounding electrode conductor). Often this is not practical or safe and is usually only an option if the site is shut down for preventative maintenance or other reasons.

This test can be conducted by a single person in roughly an hours’ time but is more practical with two people. Placement of the leads for long runs can also cause errors if they run parallel and close to each other.

Recapping this test method we see that it is easy and straight forward to use but has a few limitations. It requires a sizable amount of real estate for running wires and test rods. Isolation of the grounding electrode system under test is necessary to get good results and it takes a fair amount of time even with two people to perform.

Let’s now look at the Clamp-On test method to do the same job. This method has been in use since the mid-1980s. The testing principal is similar to the Fall-ofPotential in that a signal is injected and a result is measured. The difference is that, in the case of the Clamp-On method, a voltage is injected and a current is measured.

The Clamp-On ground tester has two coils 12

in the head that clamps around the grounding electrode or lead wire connected to the rod. One coil transmits (injects) a burst voltage signal (E) at a known frequency in the kilohertz range into the grounding system. The other coil measures the current flow (I) using highly selective filtering to only allow the current at the test frequency through. See Figure 3 for clarity. Again Ohms law applies to calculate the resistance of the system. There is no need for auxiliary rods to be placed in the ground or wires to connect them to the instrument.

Measurements literally can take less than a second. Another significant difference is that, unlike the Fall-of-Potential method, you do not disconnect or isolate the grounding electrode under test from other grounding systems. To achieve good test results two important criteria must be considered. First, you must clamp onto the rod or system to be tested below any point that would facilitate the injected voltage signal

Electrical Products & Solutions • January 2014

to only travel through wire. The earth must be the return path to the clamp-on ground resistance tester. Secondly, and equally important is the fact that with the Clamp-On method you will be measuring the total system resistance and therefore the series/parallel resistance component downstream from the test point should be significantly lower than the rod under test. For example, if you are measuring a ground rod connected to the service entrance of the building that is connected to both building steel and the grounding electrode conductor and tying it to everything else on the line connected to the electric utility you will have a very low downstream resistance. In our example if the ground rod is known to be 12 ohms and the series/parallel resistance downstream was 0.6 ohms, the clamp-on ground tester would measure 12.6 ohms.

If the downstream path was higher in resistance because fewer grounding objects were connected and Continued on page 14

FEATURE • AEMC® Instruments therefore its’ effective resistance was 9 ohms, you would then measure 21 ohms.

If you clamped around the conductor above a continuous metal path then the signal would not travel through earth but wire only providing a false low reading usually less than an ohm. Therefore a quality measurement requires good placement of the measurement head.

The Clamp-On method provides several advantages when employed properly.

First, the system to be tested does not need to be de-energized or isolated eliminating down time at the facility and providing a safer electrical environment. An additional benefit is that you also verify the bonding is good throughout the system. Second, no auxiliary rods or wires are needed to conduct the test which means the task can be completed much faster and only requires one person.

The Fall-of-Potential method is a better choice if you must provide measurement data of an isolated system such as a single rod.

Continued from page 12

One element that both Fall-of-Potential and Clamp-On testers have in common is that the path the injected signal has to take for good results is the earth.

Comparison of test results using both the Clamp-On and Fall-of-Potential method requires some consideration in that the measurement is conducted at higher frequency typically in the 1300 to 2800 Hz range with the Clamp-On and at 128 Hz with the Fall-of-Potential tester.

In general you can expect the measurement results to be somewhat higher using the Clamp-On method because of the frequency difference and the fact that you are reading a total system. Newer instruments available provide the ability to select a test frequency which results in closer comparative readings when the frequency selected on each type of instrument is in the same range.

In Part two of this article (next issue) we will present a case study comparing the test results on a system tested with both the Fall-of-Potential and Clamp-On

Beacon Products Lights Up Atlanta’s Georgia-Pacific Center

A

n iconic fixture in Atlanta’s skyline, the Georgia-Pacific building had gone dark for nearly seven years at night because its lighting system was energy inefficient. That is no longer the case thanks to Beacon Products, a division of Hubbell Lighting.

Beacon Products replaced the building’s inefficient 1000-watt and 400-watt metal halide bulbs with modern, efficient Beacon Products Alpha LED Floods. The retrofit incorporated 60 Alpha LED flood lights, including 8 ALU-36NB-90W-6x6, 22 ALU-60NB-136W-6x6, 27 ALU-72NB220W-2x2, and 3 ALU-72NB-170W-5x5.

With the retrofit, Beacon Products was able to reduce the installed wattage from 64,800 to 10,162—the aforementioned 75% reduction in energy consumption.

“The energy reductions and savings produced by new efficient technology such as the Beacon LED lighting, gave us a costeffective way to re-illuminate the iconic Georgia-Pacific Center while continuing to meet our sustainability goals,” according to Ian Hughes, senior vice president of JLL, which manages the building. Hughes noted that the new Beacon LED lighting dramatically cut energy consumption cost from approximately $55 to $14 a day.

Whether pole mounted, wall mounted or base plate mounted, Beacon Product’s Alpha LED Floods eliminate light spill and light trespass, making them an ideal instrument for lighting commercial facilities in residential and urban settings. Additionally, the Alpha can be specified for aiming either below horizontal or above horizontal, and the 6 standard NEMA beam spread options allow you to place light wherever you want it.

The Beacon Products installation has moved the Georgia-Pacific Center, a LEED® Silver certified building, significantly closer to its goal of reducing energy consumption by 20% by 2020.

Canada: Conergy Completes Commercial FIT Rooftop PV Plant Project in Ontario PV solutions provider builds 583kW PV plant in Prince Edward, Ontario Conergy continues to support the solar energy industry in Canada, specifically the FIT Program in Ontario by completing a 583 kilowatt photovoltaic power plant on a local commercial building in Prince Edward County. PV solution and service provider Conergy acted as the general contractor for the project, engineered and constructed the project, supplied the components and was responsible for the planning and implementation.

“This project is milestone for Conergy in Canada as the largest rooftop EPC project completed to-date for Conergy under the Ontario Feed-in-Tariff program,” said Jared Donald, President of Conergy Canada. “It shows our strong market position in the country, where we were awarded the honor of “Distributor of the Year” in 2012. Ontario remains a very attractive market where Conergy expects continued growth despite the changes in Ontario’s FIT rates.”

The solar system consists of approximately 2,500 Conergy ON solar modules and is expected to produce more than 700,000 kilowatt hours of clean solar energy for the commercial office and storage building annually. The solar installation will reduce the commercial building’s CO2 emissions by more than 550 tons annually. That’s the same amount of CO2 sequestered by 411 acres of forest land each year.

24

This project is the first in a series of EPC projects that Conergy intends to construct, coming from Conergy’s own development portfolio as well as the ones of Conergy’s local partners. “Our entry into the development and EPC markets in Canada is a natural progression from our historical B2B distribution business and aligns with our extensive global large project experience” said Anthony Fotopoulos, CEO Americas of the new Conergy holding company. “The new FIT3 rules and pricing are requiring companies in Ontario to find innovative ways to find cost efficiencies

Electrical Products & Solutions • January 2014

in order to effectively compete – our focus on EPC and development will help ensure that Conergy and its partners are able to thrive throughout these challenging market changes.”

PV as a cost effective and predictable energy source in volatile electricity market The Feed-In-Tariff was introduced by the Ontario government in 2009 under the “Green Energy Act” to promote the renewable energy industry and create employment throughout the province. Despite the provincial government’s efforts, there are still disproportionally high fluctuations in electricity costs in the Ontario energy market. End consumers can only ensure stable costs by taking their energy generation needs into their own hands. These commercial building tenants are experiencing energy independence first hand and will benefit from stabilized, predictable, secure and reliable energy produced by the solar energy system on the building roof.

The commercial business in the building on which the Conergy plant is located will quickly receive the benefits of clean solar energy because the building owner will see about an 18% return on their investment and break-even after only 3.5 years. This makes solar panels on commercial and residential buildings a very cost-effective alternative to electricity from the grid. ❏

CBS ArcSafe Introduces Remote Racking Solution for Popular GE AK-1-25 Low-Voltage Breakers CBS ArcSafe® is proud to offer the industry’s first remote racking solution with circuit breaker-specific tooling for General Electric’s line of GE AK-1-25 low-voltage power circuit breakers.

When used with a CBS ArcSafe RRS-2 configurable remote racking solution for non-rotary racking mechanisms, the GE AK-1-25 tooling allows technicians to remotely rack the breaker IN or OUT from an increased distance while stationed up to 300 feet away, outside of the arc-flash-hazard boundary. This newly designed tooling is compatible with all GE AK-1-25-style breakers operating on any voltage, with current ratings up to 600A and up to a four-high configuration. These GE AK-1-25 circuit breakers are generally used for protection and control of feeder and branch circuits, including equipment in buildings, industries, and power stations.

Like all CBS ArcSafe remote racking and switching solutions, the RRS-2 GE AK-1-25 racking solution attaches to the enclosure using specially designed magnets that ship with the unit. The tooling is lightweight, portable, and ideal for remote operation in hard-to-access areas.

Thanks to CBS ArcSafe’s patented remote racking solution that allows the operator to rack the breaker from up to 300 feet away, the need for hot and bulky personal protective equipment (PPE) is greatly reduced, as is operator fatigue.

Appleton Expands Plug & Receptacle Family with New M-Line Multi-Pin Connectors Appleton, the number one brand in industrial electrical products, today unveiled its new M-Line(TM) Multi-Pin Connectors for heavyduty and hazardous locations up to 600 Vac/Vdc. “Our new M-Line connectors allow customers to go far beyond four poles and in excess of 1,000 amps,” said Eric Goldberg, Director of Hazardous Products Marketing. “With the addition of the M-Line to our PowerTite® plug and receptacle family, Appleton now brings to market the widest range of connection solutions for the industrial marketplace.”

Designed to safely connect and disconnect power, control and instrumentation equipment, M-Line connectors help industrial facilities achieve increased operational flexibility and productivity. When used as back-up power connections, the connectors minimize downtime by allowing employees to quickly switch to generator power in the event of a main power failure. When employed in a pilot-plant or small batch process, they enable faster configuration of equipment while eliminating the time and expense of hard-wiring. If mounted in portable equipment, the connectors give the flexibility to deploy equipment when and where it’s needed.

Adding value wherever they’re installed, Appleton M-Line connectors are available in two versions. The MEP Series is purposeengineered for hazardous ATEX/IECEx locations while the MN Series brings M-Line advantages to heavy-duty but non-hazardous environments.Both models share plug-and-play simplicity to minimize installation and maintenance costs while providing IP68 environmental protection.

Standard and custom configurations — combining a wide range of conductor numbers and sizes, contact materials, and termination options — mean there is an M-Line connector to suit almost any application requirement. Choice is also available in cable support/retention methods, as well as shell materials (anodized aluminum, brass or stainless steel).

DE-OX® Oxide Inhibiting Compound from ILSCO ILSCO Celebrates 120 years in 2014… ILSCO’s De-Ox® oxide inhibitor is available in three distinct formulas. The standard non-grit, petroleum based formula is suitable for aluminum and copper connections. It performs very well in keeping moisture and air from penetrating the connection, thus preventing oxidization and therefore prolonging the life and integrity of the connection.

Our De-Ox-Z zinc formula contains zinc flake additive and is designed for use on aluminum or copper connections. ILSCO’s De-OxC copper formula contains copper flake additive formula is designed for use on copper connections. In both cases, the flake filled formulas act as an abrasive that roughs up the smooth mating surfaces of the conductor and connector, providing an enhanced bonding between the two surfaces. The advantages of the enhanced flake filled formulas include better holding strength and cooler operating temperatures. The flakes also act as a thickening agent that holds the De-Ox in place or helps keep it packed tightly in the connection, especially under surge conditions.

All three De-Ox formulas are available in a variety of different packages and sizes including bottles, tubes and packets.

Milwaukee® Introduces Inkzall™ Permanent Markers & Stylus- Optimized for the Jobsite Milwaukee Tool Corporation continues to expand their Hand Tool offering with Inkzall™ Jobsite Markers, a new line of writing tools designed and optimized for jobsite use. Featuring clog resistant tips and aptly named Inkzall™ for their ability to write through dusty, wet or oily surfaces, the new line will include fine and medium point permanent markers, as well as a stylus/marker combination tool that was designed for use with gloves on touch devices such as iPads and iPhones.

“Most professionals have a permanent marker with them at all times, but the options available today were simply not designed for the materials and rough conditions on a jobsite,” says Bobby Shaw, Group Product Manager for Milwaukee Tool Corporation. “The number one complaint is that competitive marker tips do not keep their shape and easily “mushroom”. The new Milwaukee Inkzall™ markers were specifically designed to alleviate this problem with durable tips that hold up to use on rough surfaces such as OSB, cinderblock and concrete.”

For added user convenience, the markers were optimized with a proprietary ink for faster drying times to reduce smearing markings, without drying out quickly when the cap is left off. Complete with a built-in hard hat clip for easy storage and access, all Milwaukee Inkzall™ solutions were designed from the ground up with the professional tradesman in mind.

Confirming Milwaukee’s commitment to best-in-class durability and their relentless mission to provide innovative solutions to the end user that will increase productivity, the new Inkzall™ products will launch in February 2014.
