【Abstract】 The correction method for grounding resistance of grounding mesh is complemented and improved. Here the grounding mesh is buried in two-layer soil and the grounding resistances are measured by compensating method under different distances between the main grounding mesh and the backflow pole of current. Several groups of correction curves of grounding resistance errors and those of the position of voltage poles are obtained. These correction curves can be available for reference in engineering measurements.更多还原
