instantaneous overcurrent relay

基本解释

For backup protection against high resistive ground faults, there will be a dual polarized directional overcurrent relay, inverse time with instantaneous trip attachment.
对于后备保护装置防止高阻抗接地故障，将配置一只双极方向过电流继电器，同瞬时跳闸附件的时间成反比。

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.
该继电器采用集成电路构成，集线路的速断保护、过电流保护及三相一次重合闸于一体。
