Original Abstract

This contribution is focused on evaluation of touch voltage quantity during a permanent ground fault in compensated distribution network with wide size of capacitive current 812 A. The touch voltage was evaluated near distribution transformer station 22/0.4 kV with the earthing system interconnected with the earthing of the neutral conductor of the LV network (0.4 kV). The data were recorded during real experiment, where low-impedance and arcing ground faults occurred. The fault was performed by conductive connection between faulty phase and iron part of the station which is connected to its earthing system. In this case, the fault current could achieve maximum quantity. (Influence of compensated distribution network operation with wide range on a touch voltage)
