| Abstract: | A line protection setting program for power system zero--sequence current is developed in which several problemsare solved: the calculation 'method for changing operating mode by modifying impedance matrix, the analysis of zero-sequencemutual coupling of lines, zero-sequence analysis in the course of non--three-phase operation and the calculation for protectionrange of zero-sequence current. |
