Answer / chennurupavanireddy

we can improve power factor by connecting capacitors in
parallel with the circuits so that they compensate lagging
components and improves the power factor there by the
efficiency of the circuit increases.

Answer / vijay patel

We Can improve power factor (1)by using shunt capacitors (2)
By using phase advancer (3)by using synchronous condenser

Answer / chetan

KVAR Required is

KVAR = P [tan (phi 1) - tan (phi 2) ]

where P = total KW
phi 1 = angle corresponds to power factor to be improved . ie cos ph 1 = 0.9

phi 2 = angle corresponds to power factor given . ie cos ph 2 = 0.7

Answer / k.prakashchandra

KVA^2 =KW^2 + KVAr^2. Reduce KVAr to improve pf

Answer / khalid mohammed yousf

S=V.I (AV)
S = (P^2 + Q^2)^(1/2)
cos ϕ =S/P
Q=(S^2-P^2)^(1/2)
Q=(E^2)/X
C=(1/2*PI*F*Xc)
C IS shunt capacitor using to improved power factor

Can i use the B-curve MCB instead of C-curve MCB
