接地故障信号继电器 earth-fault relay
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。
For backup protection against high resistive ground faults, there will be a dual polarized directional overcurrent relay, inverse time with instantaneous trip attachment.
使用者可将继电器接地故障跳闸电流设置为高于最高值几毫安，以准确测量系统充电。
User is able to set the ground fault trip current of the relay just milliamps above the highest level, to accurately measure the system charging.
后备继电系统将设置第一、第二与第三区方向距离继电器，以防相位故障与接地故障。
The backup relaying system will have first, second, and third zone directional distance relays for protection against phase and ground faults.
