故障信号

If the high frequency signal of line protection could not pass through the channel or be normally transmitted, the protection might create failure to operate or maloperation, and it influences the safe and steady operation of the system.

当系统出现故障时，如果线路保护的高频信号不能通过通道正常传送，则有可能出现保护拒动和误动的现象，影响系统安全、稳定的运行。
