RGDAT-A 70/C
Indoor directional Fault Passage Indicator
Low cost, easy to use device, suitable for the monitoring and protection of MV lines with different earthing arrangement (isolated, compensated, etc.) RGDAT A-70/C is easy to install and intended for indoor mounting in secondary substations of distribution network and complies with Enel Global Standard RGDAT-A70 GSTP001.
Benefits
Easy and quick installation thanks to its split core sensors.
Fault location for fast network reconfiguration.
Features
