This paper describes the mechanism that multiple reignition of breaker can restrain or increase progressively the switching-overvoltage during switching off inductive or capacitive load.

论述了开关在开断感性或性负载时多重燃对过压抑制或递升机理。

Switch that fellow off!

别让那个家伙再讲下去!

In a10kV distribution system,when shunt ca-pacitors are switched off by vacuum circuit breakers,restrike overvoltage often occurs.
