The power factor of the fixed load is 0.8, now the p.f is varying from 0.8 to 0.5.
Could the power factor on electrical system can affect the registration of the kwhr meter or the CT/PT?

In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.
