I have a 1000 kVA Transformer(11kV/0.415kV) and a APFC panel
of 400 kVAR(LT).Now if i want to remove the LT APFC panel
and install a HT(11kV) APFC panel on the HT side is the HT
APFC panel will work same as the LT APFC panel(improve the
power factor),if yes what will be rating of the HT APFC
panel?what is the formula to calculate HT APFC panel rating???

Answer / k.prakashchandra

The power on HT side is equal to power on LT side +
3%(1.6%). The power rating of APFC remains the same.

Answer / kathiravan

Since the PF is corrected "before" the bank is connected
(EX:A--------B---------------C----------------D-----------E.
Suppose If the bank is connected the location @"C",the PF will be corrected from location A to C only,where as location C to E will not be effected by the installation of location C)there wont be much effected weather to locate capacitor either primary or secondary of the transformer.Rating of the capacitor must be the respect of HV/LV supply voltage.
