Geomagnetic Disturbances: A Danger to the Power Grid

How the power industry is responding to geomagnetic disturbances MARK LAUBY, North American Electric Reliability Corporation In 1989, the Québec grid collapsed as equipment protection relays tripped in a cascading sequence of events. Six million consumers were left without power for up to nine hours. The cause of th...Read More

Avista Utilities Tackles Smart City Initiative

Launching a smart city with “economies of scope”

BY JESSE BERST, Smart Cities Council

The race to implement “smart” systems is not just a big-city issue. Some of the most interesting examples are occurring in mid-sized cities such as Chattanooga, Austin, and San Jose. For instance, consider Spokane, a city of 210,000 in east-central Washington State near the Idaho border, where a smart cities effort is being spearheaded by Avista Utilities, a Washington-based utility that generates, transmits, and distributes electricity to customers ranging from small residential to large industrial.

Safe Grounding in Substations

How to guard utility personnel from shock hazards

BY JEFF JOWETT, Megger

In the power industry, safety is just as important a function as performance. Safety considerations, parameters, and methods of implementation are an integral part of any electrical system. A most important element is the grounding system. This system performs several functions, not the least of which is safety. Substations are active in fault clearance, and personnel working in and around them, as well as pedestrians passing in the vicinity, need to be protected. When a fault condition occurs, the grounding electrode (grid) must be sufficient to equalize potentials both in and around the substation. (more…)

Wireless Technology for Electric Utilities

Moving the intelligence around the Smart Grid

BY MARY BETH SMITH, TESSCO

The electric industry is making the transformation from a centralized, producer-controlled network to one that is less centralized and more consumer interactive. An automated, widely distributed energy delivery network, the Smart Grid, is characterized by a two-way flow of electricity and information, and potentially is capable of monitoring everything from power plants to customer behavior to individual appliance performance.

How to adopt best practices to improve reliability and reduce costs

BY PHILIP CHARLTON, Utility Arborist Association

Electric utilities have always faced the challenge of determining the optimum frequency of maintenance operations for the control of trees and brush growing near the electric system. Utilities must balance the cost of maintenance with the cost and impact of avoiding or deferring action. (more…)

Underground Smart Grid

Exploring technologies that improve system reliability and resilience

BY PHILL FELTHAM, Editor-in-Chief

In recent years, the cost to bury high-voltage power lines has decreased dramatically. The American Transmission Company reports that installation costs for underground transmission lines (over 100 kilovolts) are now only 2.5 to 10 times the cost of an equivalent overhead line. Consequently, the number of underground transmission line projects has exploded in recent years and the number of underground high-voltage power lines operating in the United States have dramatically increased.

The Truth About Cast-Resin Transformers

Debunking the myths surrounding aluminum usage

BY SCOTT MAY, VIJAI NARAYANAN, ANDREW LAWLESS, Siemens

Much has been written about the use of aluminum versus copper for transformer conductors within the electrical industry. Aluminum conductors have been used successfully in the electrical industry for more than 100 years; unfortunately, misconceptions about their applications still exist. In Europe, aluminum has been used as the standard material for cast-resin transformer windings for many decades. (more…)

How Ontario regulation can improve electrical safety

BY BILL KHASHFE, London Hydro

According to the 2012 Ontario Electrical Safety Report, 35 percent of the province’s electrical-related fatalities in the past 10 years were attributed to power-line contact. Equipment specifications and electric utility construction plans within Ontario’s power industry, only a few decades ago, lacked regulation. Each utility developed its own policies. (more…)
