The SE earth fault sensor is used for reliable detection of earth fault currents in medium-voltage networks. It is connected to the display device via a copper cable, with the response value being set directly on the respective display device. The sensor is mounted on shielded conductors and detects the total current via a multi-layer steel band that is placed around all three phases. The separable design allows for easy retrofitting in existing systems. The fully encapsulated design ensures robust operation.
