Power Quality Cabinet – HYSPC three-phase load imbalance automatic adjustment device – LASTONE Detail:
Overview
Three-phase imbalances are common in low voltage distribution networks. Due to the existence of a large number of singlephase loads in urban and rural networks, the current imbalance between the three phases is particularly serious.
The current imbalance in the power grid will increase the loss of the line and transformer, reduce the output of the transformer, affect the operation safety of the transformer, and cause zero drift, resulting in three-phase voltage imbalance, and reduce the quality of power supply. In view of the above situation, our company have developed three-phase unbalanced automatic regulation device for the purpose of optimizing power quality and realizing energy conservation and emission reduction.
The device filters over 90% of the zero sequence current and controls the three-phase imbalance within 10% of the rated capacity.
