Abstract :
The transient voltages generated by a SF6 circuit breaker during switching off the shunt reactor may cause power quality problems in the transmission system. This paper proposes a practical SF 6 arc model for studying the shunt reactor switching transient phenomena. The proposed model includes a time-controlled switch, Mayr´s arc model with parameters estimate, and TAGS for CB energy conservation and dynamic conductance control. Three cases are performed to test the usefulness of the proposed model. Results obtained are compared with the calculated data. It shows that the proposed CB model is relatively accurate to characterize the shunt reactor switching transients
