The BPH series of three-phase load control device developed by HCRT can suppress the unbalance of three-phase currents in electric networks. The device effectively quenches electric network resonance and realizes dynamic reactive compensation rapidly. It can finish the interconversion from rated capacitive reactive power to rated inductive reactive power, and is able to realize the compensation of impact load, no matter if the system is experiencing over-compensation or under-compensation. This is where the traditional reactive-load compensation equipment fails. This device integrates energy savings and other features, and it is suitable for all kinds of working conditions.
After installing the three-phase load control device, it will improve the unbalance of three-phase loads effectively. This is detailed below:
-The three-phase load current of transformer lead-in wire is balanced, which will decrease the loss of transformer efficiency.
-The three-phase voltage of transformer output is balanced, which improves the quality of power supply, and extend the useful life of the equipment.
-The three-phase power factor can reach higher than 0.95.
-It can decrease the current of zero lines and the loss of power supply lines.
