Due to the specialty, REF relay is a current relay with very high sensitivity or a voltage relay with very low acting power.
由于零差保护的特殊性,零差继电器本身就是一只灵敏电流继电器或动作功率很小的电压继电器。

With the advantages of small size, light weight, lowpower dissipation and fast action, polarized magnetic system has been widely applied to military and civil electromagnetic relay.
A kind of intelligent compound switch using for reactive power compensation of low voltage, using a parallel structure of bidirectional silicon-controlled and magnetic latching relay was introduced.
