Our short-circuit and earth fault indicators as an essential building-block

in substations & secondary substations

Our short-circuit and earth fault indicators make it possible to combine the advantages of different location methods. This makes it possible for the first time to prioritise and weight the methods in order to perfectly match them to the respective application.

This combination makes our devices particularly suitable for use in secondary substations. Of course, these advantages also come into play directly in the substation.
