Any one Give me formula for to increse the power factor,
0.8 to 0.95, How much the KVAr Required
Answers were Sorted based on User's Feedback
Answer / thowsif_emerson_csm team
Calculation of Required Kvar:-
Initial P.f-PFi , Desired P.f-PFd and Real Power of Load in
KW...
KVAR=KW(tanAi-tanAd)
where,
Ai=Cosinverse(PFi) = Initial Power Factor Angle.
Ad=Cosinverse(PFd) = Final Power Factor Angle.
For Example:-
PFi=.85 & PFd=0.9 & Real Load=50 KW
For this required KVAR is 6.7 KVAR....

Answer / sonam sherpa
P.F = M.D*(Tan(cos-1 x)-Tan(cos-1 y))
M.D - max. demand.
x- Actual power factor
y- Required power factor
