Электрические перенапряжения в сети электроснабжения при отключении короткого замыкания

An electrical network after the short circuit disconnection has been investigated. There are two electrical circuits allowing to explore the basic frequency response of network overvoltages at short circuits. Calculation results and computer simulation of transients have been compared to experimental research. For repeatable, trouble-free conduction of the experiments with short circuit disconnection the simulation switchboard was used. In the experiments, the real network parameters were kept. The procedures for reducing overvoltages, are presented.
