Comparison of two vacuum circuit breaker arc models for small inductive current switching

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.
