Research of shunt reactor switching test for 1100kV UHV circuit-breakers

High voltage circuit-breakers switching shunt reactor is ascribed to small inductive current interruption. What's more, circuit-interaction between the breaker interrupter and the surrounding circuit can result in transient voltage with high amplitude and high-frequency, which is a great threat to the power grid. Particularly, the re-ignition overvoltage of Ultra-High voltage circuit-breaker will be very high on account of the large switching inductive current, therefore, it is very important to test and verify the inductive load switching capacity of the UHV circuit-breakers in the high power test station.
