A break anywhere in the circuit may cause the lights in the neighbourhood to go out.

路上任一处断路,都会使这一带的灯熄灭。

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

力系统中使用真空断路器切除无功补偿用并联容器时,容易产生燃,并联容的安全运行。

This paper introduces the working principle and blockdiagram of impulse magnet controlled discharge method that is used in the vacuity tester.
