how can alculate the apfc panel rating?..

Answer / karanth.sp

The PF of the connected load to a particular transformer is
to be asssuemed or known exactly.If the transformer is
already loaded you can kow the running PF by PF meter
connected.IF the PF is say 0.7 & you want to improve to
unity.You must add a capacitor of Total load in KW multiply
by a factor of 1.02.That is the value of Capacitor in KVAR.
Formula is PF (cos0)=0.7 Tan01=0.963
improve PF(Cos0)=1 Tan02=0
KVAR Required= P(Tan01-Tan02)=P(0.963).
This shall be devided in to number of stages as required.

Answer / bala.a

simple method
the apfcr panel reating willbe 1/ 3 of transformer rating
Ex ample
1600 kVA -T/F
1600/3 = 533= 500 OR 550 KVAr you may be recommended
