All detector products are based on Protrol's well proven and patented method for detection of earth faults. The sensitivity equals that of the best relay protections in the market, and the directional detection works also at the harsch conditions of arcing earth faults and single transients. 

The algorithm for earth fault detection does not require any voltage transformer which results in very cost efficient fault detectors with a high sensibility for pass-through faults, also in networks with low earth fault currents.
