Contents
This unique reference presents new data on the flow of ground currents and stray voltage which will be of tremendous value to electrical utility engineers involved with system coordination of relays and selection of breakers and fuses. Drawing on his nearly forty years of experience as a utility engineer, the author presents detailed electrical analysis as well as information drawn from actual court cases involving stray voltage and ground currents. The book is written with a problem-solving focus, with example calculations provided.
First-time released results of empirical tests to determine the paths ground currents take, what voltages develop, what impedances they pass through, and how dangerous they really are
Impact of ground currents and impedances on operation of fuses, reclosers and relays during ground fault conditions
How understanding stray voltage can help you avoid costly lawsuits
