Minimum ratio of short circuit currents from solidly earthed network aspect

Single-phase and phase-to-earth short circuit are often faults on power networks. Determination of single-phase to three phase short circuit current minimum ratio that satisfies solidly neutral earthing criteria is important into power system analyses. Calculation method for the maximum earth fault factor and the minimum ratio of short circuit currents, when the network is considered solidly earthed are presented in this paper. The proposed method is simple and applicable into power system analyses.
