Harmonic source :
Variable frequency power supply for the production line of plastic heating process, each phase current is around 940A.
Solution:
Installed one set of LiveSine’s Active Power Filter (Model: ACTSine-300-3-A).
Results:
Total current harmonic distortion rate decreased from 38% to below 3.8%
Harmonic inhibition rate > 95%
Power factor > 0.98 consistently
