Answer
# 3
KVAr = KW(multiplication factor )
1320(tan@1-tan@2)
cos@1-intial P.f
cos@2-final P.f
kvar=1320(0.541)
Kvar=715

Answer
# 6
Kvar=KVA(1-P.F)
KVA=KW/P.F
Kvar=Kw(1-P.F)/P.F
=1320(1-0.98)/0.98
=250

  Re: how to caluculate APFC panel rating, my running Load is 1320KW, Present P.F 0.76 to 0.8 we need 0.98 p.f
Answer
# 7
Input Initial Power Factor : .76
Input Desired Power Factor: .98
Input Load KW (KW) : 1320 KW


SO KVAR NEEDED TO ATTACHED :860 KVAR IF U WANTS .98

KVAR NEEDED TO ATTACHED :940 KVAR IF U WANTS .98
THESE 2 PANELS U NEED TO BE INSTAL ON THIS CONNECTED LOAD
AND ALSO DEMAND WILL GO DOWN
