HVDC Ground Electrode Design. Final Report

摘要

HVDC Ground Electrode State of the Art Study, EPRI Project RP 1467-1, brings together into one work a compilation of the pertinent information on all types of ground electrodes for service in HVDC transmission systems. The text discusses in brief the background of ground electrode theory and the properties of the earth and water in which electrodes are located. Detailed information on the siting of ground electrodes is presented, with illustrations of typical methods of investigation and mapping. A section describes the procedures of designing all types of ground electrodes, including formulas and sample designs of representative electrodes, with illustrations of each type. Techniques of mitigating the effects of ground current are presented, as well as testing procedures to determine the operating conditions of electrodes in service. An appendix gives the pertinent data on all ground electrodes built up to mid-1981, resulting from a world-wide survey. Also included is a glossary of geotechnical vocabulary. (ERA citation 07:014224)
