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.
Our most actual version is industry 4.0 ready by suppling actual measured currents by Modbus TCP for an integration to ABB Ability condition monitoring system.
