WebEarth fault detection. The earth fault detection unit is designed for the potentially-free detection of earth fault currents. It is suitable for insertion in the ground conductor cable of a power transformer or high power rectifier and the ground terminal. The system will give a warning if the AC or DC ground current value exceeds defined levels.
