Survey on Power System Grounding Design Practices

This paper describes the results of a survey conducted among various Electric Utilities around the world. This survey was sponsored by IEEE working group 78.1 which is presently in charge of revising and updating IEEE guide No. 80 [1]. The intend of the survey is to get acquainted with the actual international practices and methodology followed by the utilities for the design of Power System grounding electrodes, and to determine the main disadvantages or drawbacks, if any, which are beli, eved to exist in the present edition of IEEE guide No. 80, when it is used by the electric utility.
