Earth Grounding Beds - Design and Evaluation. Proceedings: Bureau of Mines Technology Transfer Seminars, Pittsburgh, Pennsylvania, June 25, 1985, and Reno, Nevada, June 27, 1985.
Recent Bureau of Mines research in earth grounding safety is documented in three separate papers. First, guidelines for the design of a 5-ohm borehole ground are presented. Next, an inexpensive practical means to construct a low-resistance bed in high-resistivity soil is described. Finally, a procedure that employs a commercial resistivity meter to measure shock potentials around grounded objects is explained step-by-step. These papers complement the material presented at an earlier technology transfer seminar and published as ic 8767.
