Application Reactive Power Compensation
Reactive power compensation
In order to improve the utilization rate of distribution transformer capacity and reduce its apparent current, the reactive power compensator is popular used in power supply system. Applying for a tuned harmonic filter to compensate power factor of the system, the harmonic resonance risk will be avoided also.
Function
♢ Compensate power factor
♢ Avoid harmonic resonance
♢ Automatic power factor controller, segmented switching, inactive power output as per the system requirment
