Grounding of a Modular Camp in Permafrost Area

Grounding of a Modular Camp in Permafrost Area

Electrolytic grounding is most often used in permafrost soils to ground the modular camp. To obtain the grounding resistance at least 10 Ohm using traditional methods, you need vast fields of horizontal grounding devices. Moreover, the ejecting effect due to constant freezing and thawing of the upper soil layer is manifested. As a result, horizontal grounding devices become located above the ground level, therefore, you need to bury them again all the time.
