Pollution-free power becoming a reality

Alternative green energy resources are becoming a reality due to advances in fuel cell technology done by Cummins Power Generation. Xin Li, senior researcher in the fuel cell field who works with Cummins Power Generation, predicts that on the basis of current progress, Solid Oxide fuel-cell based mobile power products will be commercially available in as soon as 2 to 3 years and higher powered 100-kW stationary power units will become available in 7-10 years. Fuel cell technology, the pollution-free electricity generation technology, which provides a green alternative to the combustion of gasoline and other fossil fuels, is anticipated to become the main source of energy to power electrical cars, trucks, buses and even homes. Functioning similar to a battery, which uses electrochemical conversion, fuel cells produce electricity from fuel (on the anode side) and an oxidant (on the cathode side), which react in the presence of an electrolyte. Solid Oxide Fuel Cells (SOFC), which operate on a mixture of hydrogen and carbon monoxide, are more compatible with existing fuel infrastructures including natural gas and the only by-products are water vapor and a small amount of carbon dioxide.

Calculating Arc Flash Hazard Levels

IEEE Standard 1584-2002, Guide for Performing Arc Flash Hazard Calculations, is the most widely used method of calculating arc flash hazard levels, and a realistic available fault current value provides critical input for proper evaluation. The analysis method requires a second calculation at 0.85 of the originally calculated arc fault current. This calculation is designed to transform the given available fault current and other parameters to a calculated arc flash current value. Relying on the IEEE equations to compensate for an inaccurate available fault current can yield unacceptable results.

Power Industry, Feds Move to Reduce Bird Injuries From Power Lines

The electric power industry has joined with federal wildlife protection officials to announce an updated guide on how utilities can reduce bird injuries and fatalities due to interactions with power lines. The manual, “Suggested Practices for Avian Protection on Power Lines: State of the Art in 2006,” contains detailed, technical blueprints that power companies can use to devise or strengthen avian protection plans.ed injuries. “Power companies have worked diligently with federal agencies and conservation groups to devise construction designs and transmission line siting standards that protect migratory birds,” said EEI President Tom Kuhn at a ceremony in November hosted by USFWS.  “With nearly three decades of collaboration under our belts, we’ve seen tremendous advancement in utilities’ avian protection efforts.” The Suggested Practices guide was developed under the auspices of the Avian Power Line Interaction Committee (APLIC), which has served as a clearinghouse for information and communication on avian and power line issues since 1989.  With a membership base comprising EEI, roughly twenty individual utilities, and numerous research and trade associations, APLIC has worked with the electric power industry and the USFWS to curtail avian injuriesand deaths due to interactions with electric utility infrastructure. Under the 2005 avian protection initiative, utilities are encouraged, among other things, to make a corporate commitment to protect migratory birds; train staff in avian protection practices; undertake permit compliance, risk assessment, and mortality reduction measures; and provide public awareness and education programs.  In addition, the guidelines embraced under this public-private partnership allow utilities to tailor their avian protection plans to match specific industrial and wildlife needs, promoting both bird conservation and electric reliability. “Last year, power companies significantly stepped up their commitments to avian protection by agreeing to develop and implement new conservation measures,” Kuhn said.  “The 2006 Suggested Practices guide reflects the most effective engineering practices available and provides detailed technical guidance to help utilities reach their conservation and system reliability goals.” “I very much appreciate the Fish and Wildlife Service’s collaboration and leadership in this effort,” Kuhn added.  “This continues to be an exceedingly effective partnership, and I’m pleased that EEI and so many utilities are part of it.” The updated Suggested Practices manual is available online at www.aplic.org .

EPRI Successfully Tests New Device That Enhances Power Integration

In a development that can significantly enhance the reliability of transmission and distribution systems, the Electric Power Research Institute (EPRI), Palo Alto, Calif., has completed testing of a prototype design of a solid state current limiter (SSCL), a device that restricts fault current from new generation or transmission and reduces switching surges. The solid-state technology developed by EPRI, with primary support from Con Edison of New York, addresses the challenges faced by utilities as new sources of power are introduced to existing transmission and distribution systems.SSCL restricts fault occurrences when new capacity, such as the additional generation created by independent power producers, is integrated into existing power systems, creating a greater likelihood fault current. The device alleviates the short-circuit condition and gradually phases in the new current. This current-limiting capability improves fault isolation and network protection, and helps resolve critical situations that can cause voltage sags and swells and power outages. The next step in development of the new technology is to test it at a host utility to determine if it is suitable for widespread deployment. “The successful testing of SSCL is a milestone for EPRI and the industry as we work cooperatively to enhance of transmission and distribution systems,” said Arshad Mansoor, Vice President of Power Delivery & Markets at EPRI.“This technology will allow utilities to significantly increase the capability and reliability of their existing power lines.” Currently, utilities’ only option in addressing fault current issues is to replace breakers with higher-rated equipment, a solution that may not be economical or viable because of space constraints, and the difficulties associated with outages necessary for replacement may be severe. In addition, breaker replacements alone may not eliminate mechanical and magnetic bracing issues for other equipment that high fault currents pass through. “The Solid State Current Limiter demonstrates that we now have a new piece of equipment able to safely withstand the impact of and limit prospective fault currents,” said Patrick Di Lillo, technical specialist at Con Edison.“This newly developed device can be used to mitigate the effects of the increased capacity required to serve increasing loads in our urban centers.We have already begun work to migrate this technology to higher normal current and voltage ratings.".

This installment of our ongoing series introduces short-circuit calculations, starting with the fundamentals and proceeding on through available computer programs. In previous articles, we discussed the importance of overcurrent protection, presented fundamental theorems used in short-circuit calculations and examined component short-circuit ratings. This article begins the study of calculation methods. The fundamental electrical quantities used in short-circuit calculations are voltage, current and impedance, i.e., Current = K1 x K2 where K1 is a constant, depending on whether the circuit is single-phase or three-phase, and K2 is a constant by which the various levels of voltage and kVA in a distribution system system are related to each other. Typical short-circuit calculations are carried out using line-to-neutral values of impedance, with K1 = 1. Tabulated values of impedance for conductors and other circuit components are always given in line-to-neutral ohms.

New Approach Could Bring Superconductors to More Applications

Researchers using nanotechnology have demonstrated a way to maintain high-temperature superconducting capabilities even in the presence of applied magnetic fields, such as those present in motors, generators and other equipment. Scientists say this discovery could lead to next-generation superconductors with broader applicability in the electric power sector of the economy. Magnetic fields in the past have disrupted superconductor operation by disrupting naturally occurring vortices present in superconducting materials, resulting in electrical resistance and power dissipation. Investigators at Oak Ridge National Laboratory in Oak Ridge, Tenn., addressed this problem by adding non-superconductive "nanodots" throughout the thickness of the superconducting material.

Solving An Old Grounding Problem

There's an age-old problem in electrical grounding. During the more than 15 years that I have been actively involved in equipment protection, over and over again, I have heard clients air their many concerns, frustrations and problems regarding electrical grounds, lightning and power quality issues resulting in malfunctioning or damaged equipment. In many of these cases, the root cause of erratic or improper equipment operation, as well as the inability of some equipment protection devices to properly function, turned out to be the electrical ground that the equipment is connected to. Widely used surge suppressors, lightning rods and air terminals (for facility, satellite dish sites, broadcast and communications tower protection and the like) are typically completely ground-dependent to perform their protective functions. In other words, a low-resistance electrical ground connection should always be available and working at the time of a surge or lightning strike. In addition, a reliable and consistent low-resistance ground connection is also important to reduce electrical noise in the protected equipment, and is especially desirable to enable radio-frequency transmitting and receiving equipment to operate efficiently. A great deal of time and effort is usually spent ensuring that the electrical ground at a facility is properly installed and that the resistance reading is within acceptable limits for the area.

Arc-Flash Compliance for Industrial Facilities and Beyond

At the National Manufacturing Week show in suburban Chicago last month, worker safety, not surprisingly, was the subject of a great amount of discussion, not only in various sessions but also on the exhibit floor. Arc flash, and adherence to NFPA 70E, part of the National Electric Code, was, of course, a subset of this discussion, but in a disturbing sort of way. "A big question we keep getting is 'Do we have to do this?'" said Doug Mleczko with Des Plaines, Ill.-based fuse manufacturer Littelfuse. Despite adoption by OSHA, and a definitive warning by the agency that it will come down on plant and building operators in violation of NFPA 70E's requirements, the reality, according to Mleczko, is that many still view this as an optional guideline. The other key issue, he said, is that many plant operators, frankly, don't know how to go about complying with the standard. At the show, Littelfuse was giving away arc-flash incidence calculators and promoting its educational offerings in this area.

Federal Budget Increase for Solid State Lighting Program

The National Electrical Manufacturers Assn., among others, is lending strong support to a provision in the Bush administration’s proposed FY 2007 budget that would spur the development of state-of-the-art lighting technology. The budget includes an $8 million increase for solid state lighting research and development. “The fact that the administration would provide an increase in funding for this program, while recommending cuts in others,” said NEMA President Evan Gaddis, “speaks volumes about the importance of high-quality, high-efficiency lighting to our nation. Improved lighting systems in our nation’s buildings and homes represent one of the greatest opportunities we have to save energy and ultimately reduce our dependence on foreign oil supplies.” The solid state research and development program, operated in partnership between the Dept.

Heat-Recovery Chillers: Worth the Cost?

Today's thermal energy facilities are striving to provide heating services in a more cost-effective manner, and one option being considered more and more frequently is heat-recovery chillers. But before implementing this technology, the designer should begin a detailed cost analysis to determine whether the cumulative savings in operational costs will justify the capital investment and the increased maintenance costs associated with the heat-recovery chillers and their auxiliary equipment. The first thing to do is identify all cash flows that will result from a heat-recovery project. It's a good idea to list all costs associated with the heat recovery chillers, as well as those associated with not pursuing the heat recovery project.

WESTPHAL: The ability to monitor and control a building from anywhere, anytime with an Internet connection and off-the-shelf browser software is the main advantage. Secondly, the cost of the browser software to display the web pages is free in Microsoft's Windows operating systems. LUNDSTROM: Web-based systems also can provide easier remote access to building controls for site managers and operators for troubleshooting during off-duty hours, assuming the IT department allows access via firewall ports. And the amount of time required for training building controls operators is significantly decreased, because most people are already knowledgeable about using web-browser software.

Managing Moisture and Mold

Important new recommendations have been set forth in the latest incarnation of ASHRAE's 33-year-old Standard 62.1, Ventilation for Acceptable Indoor Air Quality. The stated purpose for 62.1 is "to specify minimum ventilation rates and indoor air quality that will be acceptable to human occupants and are intended to minimize the potential for adverse health effects." The standard applies to all indoor or enclosed spaces that people may occupy and it considers chemical, physical and biological contaminants that can affect air quality. Several sections relevant to the HVAC industry establish new criteria, or fortify existing ones. Chief among them are those aimed at minimizing liquid water and the potential conditions for microbial growth in air systems. New attention has been given to the design, construction, operation and maintenance of air distribution systems—all equally critical factors necessary for providing a properly functioning system for the life of the building. Significant new recommendations are given for controlling and managing the presence of water.

The “Power Quality Study” also shows that 93% of contractors who worked on PQ projects within the 12 months surveyed performed installation rather than maintenance. “Our reader survey not only measures the power quality spike; it defines the electrical contractor’s changing role and impact in the entire sector,” explains John Maisel, publisher of Electrical Contractor . The 40% of 434 qualified respondents who expect PQ work to increase over the next few years, gave as their main reason that computers and other types of electronic equipment will require clean power. They also cite concerns about poor or degraded power quality or concerns about the integrity of the infrastructure. Additionally, 30% of those who are not currently working on PQ projects but did so in the past say they expect to be doing PQ work again in the next few years for similar reasons. They also cite problems with power availability and/or alternative energy/cogeneration. Survey respondents were also asked how they expect their volume of work to change over the next few years on each of 11 types of equipment included in the study.

Company Ownership: ESOPs on the Rise in A/E Design Firms

Employee stock ownership plans, or ESOPs, are becoming increasingly popular among firms in the architecture, engineering, planning and environmental consulting industry, according to researchers at Natick-Mass.-based ZweigWhite. ZweigWhite’s annual Valuation Survey of A/E/P and Environmental Consulting Firms finds that the percentage of firms with ESOPs has increased from 17% in 2002, to 22% in 2003, and finally, to 26% in 2004. “ESOPs have been around for more than 30 years, but seem to be gaining in popularity in the [A/E] industry in recent years. One reason may be the legislative changes effective in 1998, which made S-corporations eligible to sponsor ESOPs,” said Ian Rusk, ASA, a ZweigWhite principal who specializes in financial advisory consulting. Another reason may be simple demographic forces. The A/E/P industry is a highly fragmented one, with tens of thousands of companies, many of them relatively small (under 100 employees) and still owned and operated by their founders. “With many of these first generation owners being of the baby-boom generation and nearing retirement, and given the tax efficiencies of ESOPs, it's not surprising to see more firms employing them as a tool to manage major stock redemptions,” said Rusk. He further explained that the tax advantages of the ESOP include the ability of the company to deduct the principal portion of ESOP debt and redemption of shares through contributions to the ESOP plan.

The Benefits of a Structured Cabling Master Plan

More often than not, data center managers resort to a dynamic approach in populating a data center with IT equipment. This approach accommodates the ever-changing requirements of business operations, which in turn drives the need for new and often the latest IT equipment available. Any void felt in IT capacity/capability requires an almost instantaneous solution due to our heavy reliance on IT equipment and infrastructure that has come to be the life line of any business. Equipment availability today has become less of a speed bump due to the quick response time by vendors/manufacturers in supplying product.

Letters to the editor

It is quite unsettling to read the theme implicit in "Where There's Fire, There's Smoke," (January, 2001). That "Health-care facilities aren't typically evacuated in the event of a fire ..." might be true (evidence would be welcomed), [but] mechanical smoke control is not the prime means of reducing the level of risk of death or injury as low as reasonably practicable (ALARP).

Turf Wars Between Design Professionals

As if architects and engineers did not have enough of their own problems in the form of liability suits, competition from contractors and the growth of design/build, the design professionals are now "at war" with other sectors of their own community.A few years ago the battleground involved architects and engineers, and focused on which profession had the legal right to design buildings.
