High-Resistance Grounding in the Cement Industry-A User's Experience

The use of properly applied high-resistance grounding, with a method of tracing and locating the first fault, offers many advantages to the electrical power system including suppression of transient overvoltages, continued operation on the first ground fault, fast tracing of the first ground fault, and minimizing flash hazard. These benefits along with first-hand experience with a 480-V distribution system are discussed.
