The Demand Response Revolution

Progress, challenges, and the road ahead

BY OMAR SIDDIQUI, Electric Power Research Institute

For decades, utilities have been deploying demand response to achieve a variety of load shaping objectives, most notably peak reduction in response to grid conditions. Since their inception in the 1990s, independent system operators (ISOs) and regional transmission organizations (RTOs) have also been dispatching demand response along with supply-side resources to help maintain the reliability of bulk power systems.

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…)

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…)

How to prevent failure with partial discharge testing

BY HENNING OETJEN, Megger

Partial discharge (PD) measurements are increasingly used as a reliable and non-destructive diagnostic method to detect weak spots in the insulation of underground cables. Routinely, partial discharge measurements are utilized in laboratories for testing cable reels prior to commissioning and in the field to verify installation quality. (more…)

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…)
