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...

Hand Safety - Protective Gloves

Rubber insulating gloves are among the most important articles of personal protection for electrical workers. To be effective, the gloves must incorporate high dielectric and physical strength, along with flexibility and durability. For superior performance they should meet and/or exceed the requirements of current American Society for Testing and Materials (ASTM) D120 specifications. Gloves should also be electrically tested following ASTM D120/IEC903 specifications.

A glove system usually consists of:
Rubber Insulating Gloves: Classified by the level of voltage and protection they provide.

Liner Gloves: Are used to reduce the discomfort of wearing rubber insulating gloves in...
