Electrical power transmission networks are protected and controlled by medium and high-voltage circuit breakers. Breakers are meant to make and break the flow of electrical currents in transmission ...

Arc Flash safety has become as important a topic in the industry as electric shock protection. Few electrical workers would consider working on a 13.8kV system without their proper voltage rated ...

In its common form, grounding is typically thought of as no more than a rod driven into the earth in order to provide a safe diversion of lightning strokes. In a ...

“Energy efficiency” is the latest buzz phrase since the Energy Policy Act of 2005 (EPACT) was signed in August. Both short- and long-term projections indicate the era of "cheap energy" is gone in ...

The impact of the Enron bankruptcy has been both predictable and at the same time somewhat surprising for the marketplace. Short-term energy and commodity prices have seemingly been unaffected by the ...

Transmission lines have become a staple of our landscapes – they traverse an incredible range of environments, climates and terrains, leaving lasting images. Their longevity is at least partially ...

Existing AC transmission systems are operated with three physically distinct systems of conductors referred to as “phases”, where sinusoidal voltages and currents in each are offset with respect to ...

The business case for AMI deployment has often been made palatable to the regulators on the basis of widespread business benefits for the utility and the ratepayer. While present deployments have ...

Batteries are among the least expensive pieces of equipment in a substation, and they are the heart that keeps the protection and control system running. Despite this, they are often not maintained ...

When the initial Urgent Action 1200 standard was issued by NERC following the 9-11 attacks, it was primarily focused on protecting Energy Control Centers (ECCs) and their associated SCADA/EMS systems.

Energy supply – or lack thereof – has been a fundamental challenge of energy providers in recent years. Compounded with the rising cost of fuel, heightened environmental concerns, and an ever ...

As electric utilities face ongoing demands for better service and fewer, shorter outages, they look to include the latest ‘smart' technology in their operation centers. We've asked three industry ...
