Abstract
A system and method for a branch current monitoring system employing a 2-Phase Wye, a Single-Phase 3-Wire or a Single-Phase 2-Wire wiring configuration that is configured to identify a phase association and a polarity for a branch circuit current sensor using the phase angle between voltage and current. Also, a system and method for verifying phase association and polarity determinations for branch circuit current sensors that utilizes real and reactive power measurements.
