Phase ID: Ensuring Sensors Are Configured to Correct Phases
How It Works
- Define reference sensors – Utility engineers pick a location with three MM3 sensors as the phase identification references for the feeder. Engineers must verify that the phase assignments are correct for these three reference sensors.
- Ample checks phase assignments – Every six hours Ample checks the phase assignment of each sensor on the feeder against the reference units using GPS timing and measured e-field data from MM3s and reports conflicts.
- Corrections made – With the data from Ample utility engineers can correct the phase configurations of MM3 sensors on the feeder that do not align with the phase ID reference units.
Correct phase assignments improve the quality of data and increase user confidence in line sensing as a trustworthy data source. Load monitoring, phase balancing, and fault analysis can be done with assurance that system data is correct. Sentient Energy’s Phase ID capabilities enable utilities to rely on sensor data and realize the full benefits of line sensing for overhead feeders.
