Abstract
The goal of this paper is to present two different methods of modelling the reignitions caused by switching of small inductive currents with a vacuum circuit breaker (VCB). Both models are presented for different VCBs which are described by their measured characteristics. For a detailed modelled system, the overvoltages caused by unloaded transformer switching are calculated and the statistical overvoltage distribution is estimated
