Geo-magnetically induced currents are triggered by geomagnetic storms, the frequency of which ranges from 0.001 Hz to 0.100 Hz. GIC will cause DC bias saturation of transformers, unnecessary relay tripping and blackouts.

中文摘要：磁暴在输电线路引发的地磁感应电流频率为0.001～0.100 Hz，这种准直流的GIC将造成变压器直流偏磁饱和，引发电网保护误动作和停电事故。

Three methods of judging gap Spark-over at power frequency spark-over test on the three phase combinative surge protector of TBP type were analyzed,namely change of indication on ammeter A1,A2 or operation of current relay.

通过对TBP系列三相组合式过电压保护器的工频放电试验，分析了三种判断间隙击穿放电的方法，即电流表A1指示是否有变化；电流表A2指示是否有变化；或电流继电器是否动作及其对放电电压值的影响。

The article introduced the 64 kbit/s serial data transmission channel for relay protection signal,which can overcome the defects of tradition high frequency channel.

模拟试验的必要性传统的高频保护收发信机在电力系统继电保护信号的传输方面起到了很重要的作用。

It is used for inside communications in the power system and for transmitting information about maintenance of transmission line,and may be also used for common public service network,and as high frequency channel,movement signal and communication channel for relay protection in power system.

用于电力系统内部的通信及输电线路维护保养信息的传送，也可用于一般的公共服务网络，作为电力系统继电保护的高频通道、运动信号及通信频道等使用，同时能起到良好导体屏蔽地线的作用。
