Detecting Ground Faults
Sentient Energy Line Sensors
How It Works
- Accurate fault magnitude measurements – Sentient Energy MM3 line sensors accurately capture peak fault current magnitude up to 10kA within 2% accuracy.
- Identification of ground faults – MM3 sensors and Ample® can distinguish between line-to-line and line-to-line-to-ground faults. Depending on the feeder, this distinction can significantly improve fault location.
- Support for dual DNP1 Masters – Sentient Energy sensors can report DNP data directly to an ADMS in addition to the Ample Analytics Platform. Ample provides sensor management capabilities plus waveform visualization.
Sentient Energy intelligent line sensors have been proven in the field to improve the effectiveness of
ADMS distance to fault calculations used to help crews locate faults quickly and for automated ADMS fault
isolation and restoration schemes.
