摘要：
An algorithm of fault location's detection and resistance's value assessment is described for overhead lines with distributed load in case of isolated neutral. The method is based on the results of measurement of line's mode parameters. A mathematical model is proposed considering the influence of the voltage of the line two wires - rail mode operation-line power automation. Capacitances are placed between each phase line and the ground to increase the accuracy of the method. Accuracy of determining the values of resistance in fault location is analyzed.
