Can reliably determine, within the community and bounds detection ma level and zero-sequence current phase short circuit faultcurrent, automatic removal of single-phase groundfault and phase fault.
User is able to set the groundfault trip current of the relay just milliamps above the highest level, to accurately measure the system charging.
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。

On account of the weak faultcurrent and unstable fault arc, the problems of the single phase to ground fault line selection in the non-solid earthed network have never been thoroughly resolved.
