This alert calculates the effect of a measured phase imbalance.
The Phase Imbalance Alert will monitor power quality. The Alert will inform the user of energy quality, efficiency, and potential asset performance degradation due to unequal line (phase) voltage.
Phase Imbalance is attributable to 3 primary causes:
-
Poor wiring connections or contactor contacts
-
Internal motor winding problems on motor driven equipment (e.g. HVAC air handlers)
-
Utility provider or facility electrical problems.
Phase Imbalance exceeding 2% adversely impacts asset performance (capacity, availability, and efficiency) due to exponentially increasing heat within the asset.
