Harmonic source :
250 alternating current charging piles, rated voltage is 220V±10%, rated current is 32A for every alternating current charging pile.
Solution:
Installed two set s of LiveSine’s Active Power Filter (Model: ACTSine-200-4-F).
Results:
Total current harmonic distortion rate decreased from 40% to below 5%
Harmonic inhibition rate > 95%
