Hi guys,
We have a industrial connection of 225 kW.
Our industry consists mostly of Induction motors and runs in night shift mostly.
So we use capacitor banks for lower factor correction. And so far we have maintained 0.995-0.999 pf (sometimes even 1) over the years.
Previously, the power factor was calculated as
P.f. = kWh / ✓(kwh^2+kvarh_lag^2)Recently, our energy provider changed there of calculation technique and our meters to record kvarh_lead also.
And new formula is
P.f. = KWH / ✓(kwh^2+(kvarh_lag+kvarh_lead)^2)Due to this our p.f. is reduced to 0.200 to 0.225
Looking at the metering reading, I can notice that kvarh_lead is increasing very fast.
What should be done to correct p.f.
Is it the capacitor bank or something else.
