The paper presents an analytical procedure suitable for the determination of the part of the ground fault current emanating from the substation grounding grid in the conditions when a particular measure has been taken to reduce it. The practical realization of this measure can be simply described as burying one bare copper wire of a certain length in the same trench as the cable feeding line. In the case of an overhead feeding line, the similar measure is denoted in the expert literature as the “counterpoise”. The presented method enables a quick and, for practical purposes, sufficiently accurate evaluation of the copper wire length providing the maximum possible reduction of the substation grid current. The conveniences of the method result from the simplicity of the formulae for the determination of the realized grid current reduction at the effective copper wire length
