摘要
In the paper the results of intermittent ground faults simulation in the labortaory model of the medium voltage distribution networks are presented. The principle of the simulator operation as well as the examples of simulated ground faults are included. Oscillograms of current and voltage waveforms at essential points of the modelled networks are shown. Further development of the simulator for modeling of more sophisticated intermittent ground faults is considered.
