About product details

Consideration must be given to the water table at the site. Factors to consider include its location in relation to the surface and whether or not it is subject to large seasonal variations. Design the earth electrode subsystem so that it makes and maintains contact with soil that stays damp or moist year round if at all possible. Penetration of the permanent water table is highly desirable. (c) The depth of the frost line even in the coldest periods must be determined. The resistivity of soil rises greatly as the soil temperature drops below 32° F. Thus for maximum stability of electrode resistance, the subsystem should penetrate far enough into the soil so that contact is always maintained with unfrozen soil. In permafrost, fault protection must be provided through the use of metallic returns accompanying the power conductors to insure the existence of a return path to the transformer or generator.
