Grounding methods in permafrost.
It is known that at low temperatures the soil resistance increases the "standard" values many times over. In ordinary loam the resistance can reach 20,000 ohm.
What should one do in such cases? How can we arrange grounding and reach the "acceptable" level of resistance?
Apart from common solutions, such as replacement of the soil or "salting", a popular and efficient method is ZANDZ electrolytic grounding, which is a stainless steel tube filled with special mixture of mineral salts.
In contrast to the widespread self-made "salting", in the electrolytic grounding ZANDZ the filler does not cause corrosion of the electrode and is not washed away by groundwater during the warm season.
