Wireless Controls Provide Affordable Building Alternatives By Dianne Pisarek, President Masco Technological Innovations
It is common knowledge that creating a “green” building isn’t the work of just one person, but rather a process that requires numerous professionals, each with their own expertise. Ensuring that a building is as energy efficient and environmentally friendly as possible remains a top priority for all involved in the development and building process - from the architect who drafts the initial plans, to the electrician who brings the building to life with power and light and, finally, the occupants settling into their new home or guests spending time in a hotel. Utilizing energy-efficient building materials and operating systems is becoming the new norm, especially as professionals and con6
sumers learn more and more about how energy-efficient buildings lower energy costs, increase efficiencies and lessen the impact on the environment.
Simply Controlling Comfort and Cost According to the U.S. Department of Energy (DOE), the residential building sector accounts for about 21 percent of the country’s total energy consumption, with lighting listed as the third highest form of energy use in U.S. households. In most homes, electrical gadgets, appliances and electronics also use a significant amount of electricity, even when they are in the “off” position. There are many ways to
Electrical Products & Solutions • November 2010
easily and affordably reduce energy use without having to sacrifice comfort and convenience, yet the DOE states that the typical U.S. family still spends almost $1,900 a year on utility bills. Facilities managers are also being challenged to find affordable alternatives to efficiently and effectively manage a wide variety of “residential” environments including university residence halls, hotels and assisted living facilities. Adding to that challenge is the need to do so without sacrificing the comfort of residents or guests.

stallations, reduced on-going maintenance costs and tremendous ROI potential for projects. The Verve 10-channel controller is easily programmed for a variety of whole or partial home lighting functions ranging from simply turning the lights on or off to dimming lights, illuminating pathways, and creating scenes for every mood or occasion. There’s no need to wire the switches to the lighting sources, making the switches totally movable throughout the home. In addition to the control of incandescent, LED and compact fluorescent lighting, the technologies have also been applied to heating and cooling controls (HVAC) for increased comfort and energy savings. Combining lighting and HVAC control with Verve’s occupancy and vacancy sensors is a great way to ensure that energy is not being unnecessarily wasted when a specific space, or even an entire home, is not occupied. They can turn off the lights
and outlet in the building. Historically, these systems have been expensive and complex – making them financially out of reach for most homeowners and resulting in less than desirable return on investment for most commercial lodging applications. In many cases, they also require extensive professional set up and programming which adds to the cost at the time of installation and, in some cases, whenever a change to the original set up is required in the future. Verve Living Systems, a new player in the control space, is bringing to market an incredibly simple, extremely affordable and highly cost effective solution for controlling energy usage in both buildings and residences. Verve’s controls can be combined to provide a variety of energy saving solutions that range from complete lighting and temperature control, to targeted control of miscellaneous electrical loads through receptacles. The products use the EnOcean protocol based on energy-harvesting (wireless) and radio frequency (battery-less) technologies and are designed to reduce the complexity of installations while ensuring a comfortable lifestyle experience for the homeowner or occupant. 8
Big Advantages for Everyone Homeowners will obviously benefit from a battery-less, wireless solution like Verve Living Systems because they not only save energy and reduce spending, but also eliminate the need for batteries, which means fewer batteries clogging our landfills. But the system also offers tremendous advantages to building operators and trade professionals including reduced complexity of in-

FEATURE • Verve Living Systems This technology has also become extremely appealing to architects looking for new and innovative ways to develop smart, energy-efficient residences and buildings. “When it comes to the home, I actually think the most innovative approach is stepping away from the object itself and thinking about the systems,” says San Francisco-based architect Sean Culman, AIA, who often recommends Verve products in his projects. “Looking at the systems holistically makes the biggest difference in the comfort of those people living in them, and the Verve technology has the flexibility that makes it possible for me to alter light levels and create scenes as we’re designing the lighting plan already built in.” The Verve system provides residential homebuilders with an affordable way to differentiate their services by offering potential homebuyers enhanced lifestyle and meaningful energy savings benefits. Architects and designers are always looking

for new and innovative ways to help their clients save energy and money, and electricians are another group helping lead the charge. Because there’s no wiring or wall boxes for any light switch utilized in the Verve system, unlike conventional hardwired switches, the wireless system can significantly reduce materials and time. “From an electrician standpoint, the best thing about Verve Living Systems is definitely the installation,” notes New Orleans electrician Chad Fabacher, who has installed the system in a number of homes. “When I was able to show other electricians just how easy and efficiently the system is installed and how much wire was actually saved, they immediately wanted to try it for themselves.” Installation costs and complexity are also reduced, along with copper wiring, wall boxes, wire nuts and conduit associated with the switches. With no three-or fourway wiring, the number of electrical connections is reduced, lowering installation time and eliminating callbacks to add, move

or re-wire light switches. In the end, a lighting and electrical control system puts the control in the hands of the homeowner. Richard Jones and his family are proud homeowners who chose Verve products for their home because they knew during their homebuilding process that they wanted a truly “green” home as the final output. “One of the best features of the system is that you can program any switch to control any number of lights,” says Jones. “For example, we have a night time switch that we hit when we’re ready to go to bed that turns the whole house off so that we don’t waste energy, which is the point of the green home we built.” And perhaps the most intriguing advantages of a system like this are the energy cost-saving benefits that come along with the installation in a home. “Harmony in the home, to us, means that everything works in sync with everything else,” says Jones. “Being able to control our environment and, at the same time, not having to pay a fortune to do that.” ❏

FEATURE • AEMC® Instruments PART 1 OF A 2 PART ARTICLE
By John Olobri, Director of Sales and Marketing, AEMC® Instruments Figure 9
Grounding Electrodes Ground resistance testing instruments have been around since the early 1930s. In fact the first test instrument introduced consisted of a null balance galvanometer, a decade resistance box and a DC power source. Years later hand crank technology provided the test voltage. Electronic instruments began to emerge on the market in the 1950s and 1960s. Eventually digital displays, data storage and automatic result calculations having have evolved into the instruments on the market today greatly simplifying the test process. Although the instruments have significantly evolved to provide higher accuracy quicker results and are easier-to-use, there are still considerable amount of uncertainty and misapplication associated with ground resistance testing. This two part article will attempt to clarify the proper use of several common procedures used for testing grounding electrode systems; the venerable fall-ofpotential test method will be discussed as well as the stakeless clamp-on test method. Before we get into the test methods a word about grounding electrodes is worth mentioning.
Grounding Electrodes The term “ground” is defined as a conducting connection by which a circuit or equipment is connected to the earth. The connection is used to establish and maintain as closely as possible the potential of the earth on the circuit or equipment connected to it. A “ground” consists of a grounding conductor, a bonding connector, its grounding electrode(s), and the soil in contact with the electrode. “Grounds” have several protection applications. For natural phenomena such as lightning, grounds are used to discharge the system of current before personnel can be injured or system components damaged. For foreign potentials due to faults in electric power systems with ground returns, grounds help ensure rapid operation of the protection relays by providing low resistance fault current paths. This provides for the removal of the foreign potential as quickly as possible. The ground should drain the foreign potential before personnel are injured and the power or communications system is damaged. 14
Ideally, to maintain a reference potential for instrument safety, protect against static electricity, and limit the system to frame voltage for operator safety, a ground resistance should be zero ohms. In reality, as we describe further in the text, this value cannot be obtained. Last but not least, low ground resistance is essential to comply with NEC®, OSHA and other electrical safety standards. Figure 9 illustrates a grounding rod. The resistance of the electrode has the following components: (A) The resistance of the metal and that of the connection to it. (B) The contact resistance of the surrounding earth to the electrode. (C) The resistance in the surrounding earth to current flow or earth resistivity which is often the most significant factor.
More specifically (A) Grounding electrodes are usually made of a very conductive metal (copper or copper clad) with adequate cross sections so that the overall resistance is negligible. (B) The National Institute of Standards and Technology has demonstrated that the resistance between the electrode and the surrounding earth is negligible if the electrode is free of paint, grease, or other coating, and if the earth is firmly packed. (C) The only component remaining is the resistance of the surrounding earth. The electrode can be thought of as being surrounded by concentric shells of earth or soil, all of the same thickness. The closer the shell to the electrode, the smaller its surface; hence, the greater its resistance. The farther away the shells are from the electrode, the greater the surface of the shell; hence, the lower the resistance. Eventually, adding shells at a distance from the grounding electrode will no longer noticeably affect the overall earth resistance surrounding the electrode. The distance at which this effect occurs is referred to as the effective resistance area and is directly dependent on the depth of the grounding electrode.
Electrical Products & Solutions • November 2010
Effect of Grounding Electrode Size and Depth on Resistance Size: Increasing the diameter of the rod does not significantly reduce its resistance. Doubling the diameter reduces resistance by less than 10%. (Figure 10) Figure 10
Depth: As a ground rod is driven deeper into the earth, its resistance is substantially reduced. In general, doubling the rod length reduces the resistance by an additional 40% (Figure 11). The NEC (2008, 250.52 (A)(5)) requires Continued on page 16 Figure 11

Ground Resistance Testing Principle Fall-of-Potential – 3-Point Measurement
The potential difference between rods X and Y is measured by a voltmeter, and the current flow between rods X and Z is measured by an ammeter. (Note: X, Y and Z may be referred to as X, P and C or H, S or E in a 3-Point tester or C1, P2 and C2 in a 4-Point tester.) (Figure 13) This method requires the service neutral and any other grounding system be disconnected. It is not necessary to carry out all the measurements when using a ground tester. The ground tester will mea-
sure directly by generating its own current and displaying the resistance of the grounding electrode.
Position of the Auxiliary Electrodes on Measurements The goal in precisely measuring the resistance to ground is to place the auxiliary
Figure 12
current electrode Z far enough from the grounding electrode under test so that the auxiliary potential electrode Y will be outside of the effective resistance areas of both the grounding electrode and the auxiliary current electrode. The best way to find out if the auxiliary potential rod Y is outside the effective resistance areas is to move it between X and Z and to take a reading at each location (See Figure 15) If the auxiliary potential rod Y is in an effective resistance area (or in both if they overlap, as in Figure 14), by displacing it, the readings taken will vary noticeably in value. Under these conditions, no exact value for the resistance to ground may be determined. On the other hand, if the auxiliary potential rod Y is located outside of the effective resistance areas (Figure 15), as Y is moved back and forth the reading variation is minimal. The readings taken should be relatively close to each other, and are the best values for the resistance to ground of the ground X. The readings should be plotted to ensure that they lie in a “plateau” region as shown in Figure 15. The region is often referred to as the “62% area.” (See 62% method below for explanation) Readings every 5-10% of the distance from x to z are suggested. The average of the closest three readings (user defined) would be considered the resistance between earth and the test point.
Measuring Resistance of Grounding Electrodes 62% Method The 62% method has been adopted after graphical consideration and after actual test. It is the most accurate method but is limited by the fact that the ground tested is a single unit. This method applies only when all three electrodes are in a straight line and the Continued on page 18 16

from X to Z, and that the readings on either side of the initial Y setting are most likely to be within the established tolerance band. This tolerance band is defined by the user and expressed as a percent of the initial reading: ±2%, ±5%, ±10%, etc.
Auxiliary Electrode Spacing No definite distance between X and Z can be given, since this distance is relative to the diameter of the electrode tested, its length, the homogeneity of the soil tested, and particularly, the effective resistance areas. However, an approximate distance may be determined from the following chart which is given for a homogeneous soil and an electrode of 1” in diameter. (For a diameter of 1/2”, reduce the distance by 10%; for a diameter of 2” increase the distance by 10%; for a diameter of 3/8”, reduce the distance by 8%.) ❏ Figure 19 APPROXIMATE DISTANCE TO AUXILIARY ELECTRODES USING THE 62% METHOD

Consider Figure 17, which shows the effective resistance areas (concentric shells) of the grounding electrode X and of the auxiliary current electrode Z. The resistance areas overlap.

Solar Energy Is Growing Up By Ken Whiteside
Among the daily reports of economic stagnation and a jobless recovery, there is one very bright spot – yes, that would be the sun. According to a Solar Energy Industries Association report, the domestic solar energy market has grown on average 69% per year during the past decade. Even during
the worst of the recession in 2009, it grew by 39%. The solar market is projected to close 2010 showing a 55% increase over last year, while the overall economy will grow only 2%. This phenomenal growth is being stimulated from two directions at once. From the top, there are the changes in government policy (and a torrent of financial incentives in the form of tax credits, rebates and grants). And there are shifts among corporations and investors. As those policies, attitudes and dollars spread through the economy and make their way to
small businesses, they support the grass roots market demand which is stronger than ever. While the funds available through various Federal, State and utility company programs make their way onto Main Street, another top-down force is becoming more evident. Corporate leaders are calling for more support for renewable energy and investment dollars are flowing. This shift in attitude among CEOs was most recently demonstrated by Stephanie Burns, chairman, president and CEO of Dow Corning Corp., when she called on the Federal government to, “establish legislative and regulatory policies to encourage rapid growth of a viable renewable energy industry and encourage consumer adoption, increase investments in research and development to support innovation in solar energy technologies, invest in renewable energy-related education, training and job creation; and lead by example in the implementation of clean technologies.” To achieve sustainability and viability as a mainstream industry and a vital part of the energy mix in the U.S., the solar energy industry needs and applauds this call to action. Elsewhere in the economy, business and property owners are ready and willing to help change the way we produce and use electricity – the interest and desire for renewable energy is in full force. The actions of one business serve as a good example of what it looks like when good policy meets demand. It also says a lot about how economic development at the grass roots works these days. There are no VC angels in this story. Dog Boys Dog Ranch is a very popular boarding kennel and spa (chiropractic and massage services are available) outside Austin, Texas where dogs go for play dates and weekend retreats in a bucolic setting of gently rolling hills studded with trees. Dog Boys is a perfect candidate for a solar electric system; plenty of space, both rooftop and Continued on page 22

on the ground, and rising utility expenses. Their investigation of funding options led them to a U.S. Treasury Dept. program called the 1603 Program – Payments for Specified Energy Property in Lieu of Tax Credits. The title pretty much says it all; the dog-folks gave up the 30% Federal income tax credit available to anyone buying a solar energy system in favor of a
grant. Between this grant and a rebate from Austin Energy, the local electric utility, Dog Boys was out of pocket about $10,000 for an $82,000 PV system. That system is offsetting 35-60% of their electricity expense, depending on the seasonal use of air-conditioning (did I mention that this is an up-scale kennel?). These savings are in turn enabling Dog Boys to grow – the money they aren’t spending on electricity is being used for expansion and improvements. Expansion in the form of more kennels means that Do Boys’ business grows – they can house more pups. And improvements to existing facilities mean they are able to offer more services. More dogs mean more dog handlers and poodle groomers, a greater variety of services means new customers and more employees. And on it goes. Projects like this one also help grow local solar businesses prompting them to hire installers, system designers, sales staff and electricians. This isn’t rocket science or a new business model. It is simply sound business development and economic stimulus being well used in a way which is, by the way, totally consistent with the concept of distributed generation. Dog Boys, however, will most likely not make the evening news. When an industry grows in this way, it doesn’t attract much attention in the mainstream press because it doesn’t provide ribbon cutting photo opportunities for politicians and economic development leaders. The emerging solar energy industry doesn’t typically include large plants and huge construction projects that make good headlines. An announcement recently that one of largest solar power plants in the country is to be built in Ohio and that two manufacturers are going to build facilities nearby included the news that 300 permanent jobs will be created. While this is clearly not the automobile industry of the 90’s when states and cities fell all over themselves to attract large BMW, Hyundai and Honda plants with their thousands of assembly jobs, solar is definitely bucking the trend of lackluster performance found in most economic segments. The solar energy industry is growing all around us, faster than we often realize and in many cases as quietly Continued on page 24 as solar energy

Product FOCUS Electri-Flex Announces SHIELD-FLEX™ EMI/RFI Shielding Conduits Electri-Flex Company announces changes to their line of shielded flexible conduits. SHIELD-FLEX™ represents a line of three shielded conduits, SLA™, EMS™ and EMCS™, that were formally known as LAS, EMS and EMSP respectively. SHIELD-FLEX™ is designed to protect sensitive electronic circuits from electromagnetic and radio frequency interference (EMI/RFI) in applications such as communications, radar and data transmission. These products accept industry standard liquidtight connectors and address the problems of assembly and grounding. All versions can be manufactured with halogen-free jacketing material, using a HF prefix. • Good Shielding: Type SLA™, UL Listed, is a flexible steel conduit with a galvanized steel core, over which a tinned copper shielding braid is applied. The outer jacket is flexible PVC with a temperature rating of -20° to 60° C while the braid offers a minimum of 90% shielding coverage. • Better Shielding: Type EMS™ offers a better shielding effectiveness than Type SLA with a temperature rating of -55° C to 105° C. EMS features a flexible core constructed of a helically wound, fully interlocked strip of bronze. An all-temperature PVC jacket is extruded over the core, resulting in a sealed, waterproof raceway when assembled with liquidtight fittings. • BEST Shielding: Type EMCS™ is a hybrid of SLA and EMS because it utilizes the same bronze core and PVC jacket as EMS but gets further screening protection from a tinned copper braid as found in the SLA product. Type EMCS offers the same working temperatures as EMS. For more information, visit www.electriflex.com

Product FOCUS Thomas & Betts’ Backup CurrentLimiting Fuse Reduces Risk of Transformer Failure Hi-Tech® 38kV Trans-Guard® OS Shorty Backup Current-Limiting Fuse Designed for Distribution and Wind Farm Applications The new Thomas & Betts (T&B) Hi-Tech® 38kV TransGuard® OS Shorty Backup Current-Limiting Fuse provides the greatest risk reduction of disruptive transformer failure of any protective device currently available. Designed for use in 26.4 to 34.5kV distribution and wind farm transformers that have a primary or secondary delta connection or that feed more than 50 percent delta-connected loads, it significantly reduces fault energy and offers a high interrupting capability for protection against ever-increasing available fault currents. This reduction in fault energy results in a reduction in arc-flash potential. As a backup current-limiting fuse, the 38kV Trans-Guard OS Shorty fuse must always be applied in series with a properly sized, low-current protective device such as an expulsion fuse or the Elastimold® Molded Vacuum Interrupter (MVI). Both devices provide fault protection over a given range of currents. The expulsion fuse or MVI clears low-magnitude currents, such as those caused by faults external to the transformer and high-impedance faults inside the transformer, which are generally below the minimum interrupting current rating of the current-limiting fuse. Backup current-limiting fuses, such as the 38kV Trans-Guard OS Shorty fuse, clear all other currents, such as those resulting from low-impedance faults within the transformer and, most importantly, limit the amount of energy from the fault source to a value below what the transformer tank is capable of withstanding. The 38kV Trans-Guard OS Shorty fuse is capable of interrupting fault currents as high as 50,000 amperes symmetrical. For more information, visit utility.tnb.com
