Three-phase power imbalance refers to the power system in the three-phase current (or voltage) amplitude is inconsistent, and the amplitude difference exceeds the specified range. Hazard: Distribution transformer power loss increased output to reduce and produce zero-sequence current, the line power loss increases, the safe operation of electrical equipment is affected, reducing the efficiency of the motor.
