There is provided a method for measuring a parameter of a power frequency current being carried by a power line.
本发明提供一种测量由电力线承载的工频电流的参数的方法。
The test results in this paper show that ZnO arrestor unit with a series gap for transmission lines is able to cut off power frequency current quickly before the circuit breaker operate.
试验研究证实：氧化锌限流元件串联放电间隙能够在断路器动作之前，快速截断工频续流。
