Original Abstract
The main aim of the contribution is verification of designed principle for earth fault location in real distribution network which is based on evaluation of voltage sags recorded on secondary side of distribution transformers MV/LV. For this purpose, series of experimental measurement in real compensated MV distribution network were carried out. During the experiments, different types of earth fault (solid, arcing and impedance earth fault) were artificially ignited and all important waveforms (secondary voltages of distribution transformer, fault currents, voltages and currents at supply substation) were recorded for further analyses. These fault records were used for verification of described method. The result of the analyses is answer to question, if it is possible to use the idea of earth fault localization method in real conditions of compensated distribution network operation.
