Description: Cold Regions Technical Digest
Introduction: Electrical grounding for temporary and permanent installations in cold regions is complicated by the existence of frozen soil. This is because • The electrical resistivity of frozen soil can be several orders of magnitude higher than unfrozen soil. • The contact resistance between the grounding electrodes and the soil, which is usually negligible under unfrozen conditions, can become significant if a veneer of ice forms on the electrode. • It is difficult to drive grounding rods into frozen soil. The purpose of this digest is to describe the factors to consider when planning a grounding system for permanent and temporary installations in regions of seasonal frost and permafrost.
