Measurement technology/ Earth fault indicator

ground fault indicator

Reliable detection of earth faults in medium-voltage networks

Earth fault indicator for industrial applications

Our earth fault indicators enable the reliable detection and localization of earth faults in medium-voltage networks. The product group includes proven designs such as the EASi and EASi-L types, the EFL earth fault indicator, and the TERRA-C type. Key features include reliable earth fault current detection, clear visual indicators directly on the network section, and different designs for cable and overhead line networks. Earth fault indicators help industrial engineers to quickly isolate earth faults and sustainably increase the operational safety of electrical systems.
