Abstract :
The reduction of switching overvoltages by means of synchronized circuit-breakers with pre-insertion resistors is studied. The influence of system and breaker parameters is ascertained. The study shows that the reduction obtainable in a shunt-compensated system is sufficient for future UHV applications. A method for the rapid reinsertion of disconnected shunt reactors is also investigated.
