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...

What Is Step and Touch Potential and Reducing Resistance To Ground?

Step Potential Step potential is the step voltage between the feet of a person standing near an energized grounded object. It is equal to the difference in voltage, given by the voltage distribution curve, between two points at different distances from the electrode. A person could be at risk of...

Infrared safety: using thermal technologies to protect workers

BY DOUG BARRY, FLIR Systems

Disconnect switches, elbow connectors, cutouts, lightning arrestors, oil-filled circuit breakers, and other electrical components tend to heat up before they fail. The ability to detect overheating on such equipment long before it becomes critical is essential for preventing costly unplanned outages and for protecting workers from exposure to potential arc flashes and faults. The experienced and well-trained know it’s crucial to heed...
