A study of switching surges in a 400/110 kV substation was carried out in order to detect the causes of severe damage to the power transformer, which happened after a busbar fault. The busbar protection generated tripping signals for several circuit breakers and after their sequential tripping, the surge arresters installed on the 10.5 kV stabilizing windings inside the transformer were destroyed. The computer simulations were carried out on an appropriate model, which was developed for the… Expand
