instantaneous overcurrent relay

基本解釋

For backup protection against high resistive ground faults, there will be a dual polarized directional overcurrent relay, inverse time with instantaneous trip attachment.
對于后備保護裝置防止高阻抗接地故障，將配置一只雙極方向過電流繼電器，同瞬時跳閘附件的時間成反比。

The relay is made up of integrated circuits. The line instantaneous overcurrent protection and overcurrent protection are combined with the once 3-phase reclosure application to form a whole body.
該繼電器采用集成電路構(gòu)成，集線路的速斷保護、過電流保護及三相一次重合閘于一體。
