    Abstract

    A novel technique for short circuit fault location in distribution networks is presented. The technique computes the fault distance as reactance, based on the measurement of busbar voltages and feeding primary substation currents. The key factor is the compensation of the load currents superposed on the fault current. This leads to the accuracy, which is even better than with the previous methods, with the other difference being, that only one or two measuring device is needed, depending on the number of primary transformers at the substation.
