In substation electromagnetic compatibility studies or insulation coordination studies it is desirable to get as accurate a representation as possible of the transients generated by faults and switching events. A method of simulating the voltage and current transients generated by a gas blast circuit breaker operation using a composite Cassie-modified Mayr model of the circuit breaker arc is described. It is demonstrated that this gives good agreement with published laboratory measurements of the circuit breaker voltage and current. The transmission line modeling method is used int the construction of the simulation algorithm of the circuit breaker circuit. A method, based on describing the circuit breaker by a transmission-line model (TLM), is used to decouple the non-linear characteristics from the rest of the network.
