Abstract :
Vacuum Interrupters could be connected in series to increase the voltage withstand capacity. This series connected vacuum interrupters would especially be useful for application of vacuum circuit breakers at transmission voltages (145 kV, 245 kV). An important aspect of series connected vacuum interrupters is sharing of voltage across the two gaps. This paper presents results of power frequency and impulse experiments on series connected vacuum interrupters.
