Measurement technology/ sensors for earth faults

Sensors for earth faults

Precise measurement of earth fault currents in medium-voltage networks

Ground fault sensors for reliable fault detection

Our earth fault sensors reliably detect earth fault currents and provide the necessary measurement basis for reliable fault detection in medium-voltage networks. The product group includes the LE earth fault sensor and the SE earth fault sensor, which are designed for different installation situations and network requirements. Key features include precise detection of even small earth fault currents, robust design for use in switchgear, and easy integration into earth fault indicators and protection systems. Earth fault sensors support targeted fault localization and increase the operational reliability of electrical networks.
