Abstract
A new method is presented for the detection and location of high resistive, permanent single-phase earth faults in medium-voltage (MV) distribution networks (20 kV). The systems considered are with unearthed or a compensated neutral and the fault resistances covered are in the range of 5 k Omega ... 160 k Omega. The algorithms of the new method are based on the change of the neutral voltage and zero-sequence currents, measured at the MV substation and also at the distribution line locations
