Sažetak
Switching operations in gas insulated substations are accompanied with multiple restrikes, especially during discinnector swiching. Overvoltages provoked by restrikes on a disconnector propagate inside and outside of the gas insulated substation. Simulation of overvoltages on different parts inside and outside of the substation have been conducted by using the computer program on the model of three phase enclosed 123 kV substation. Computer simulations give an insight of overvoltages amplitudes and frequencies in the substation. Beside computer simulations, external overvoltages were measured during disconnector switching.
