Very practical article. I have personally used Method No. 2 Clamp Meter method in dairy plant.
In most plants PF penalty starts because of only 1 weak capacitor. We check current of each step once in 3 months. If 25 kVAR capacitor shows less than 22A we replace it immediately. This small practice has saved huge PF penalty.
One more tip - Always check capacitor contactor also. Many times capacitor is healthy but contactor point is burnt, so current does not flow.
Thanks for sharing this detailed chart. Very useful for maintenance engineers.
