For correcting PF KVAr is introduced, thus formula

pf=cos A is significant

there you should have a desired PF. If for example you need
a power factor of .90 to maintain for a 30kVAR the watts
that would come will be:

A=arccos .90
A= 25.84

WATTs= KVAR/tan 25.84

= 62500 watts approx.

remember that for PF correnction it is the KVAR that is in
need of computation and not the watts so the question would
rather be, how much capacitor kVAR you need to correct the
power factor.

The question requires more details.
First the "K" represents kilo or 1000.
The real power (kW) can be thought of as the x-axis and the
reactive power (kVar) from inductance or capacitance can be
thought of as the y-axis. The hypotenuse is the
Apparent power (KVA). The relationship of Real to apparent
power gives the Power Factor, where a power factor of 1.0
simply means that you only have real power, no reactive
power. The leading and lagging VARs from capacitance and
inductance, respectively can be added numerically since
they are on the same axis.
To ask, how muck kVars are required for a given kW doesn’t
make a lot of sense because you need to include the desired
power factor.

Ic=IsinQ1-I'sinQ2
where Q1 = phi1 and Q2 = phi
I is the curent, before correction and I' is the current,
after correction.
Ic is the subject of formula.

normally Formula
Kvar= 1.732*V*I*Sin(pi)
If Pure Capacitor 90 Leads so The power factor is Unity(1)
Assume *V=415
*Sin(90)=1(But Reactive power is zero)
since I=Kvar/1.732*V*1 Eg. 1000/1.732*415*1=1.39A
other formula for Determine KW=KVAR/tan(pi)or KW=VIcos(PI)
Assume * cos(0.9)
since KW=KVAR/tan....Equ 1, take the cos invesr is equal to (0.9)=25.8419 ...Equ 2
KW=30KVAR/tan25.8419=61.94KW OR
they are more formulas
* KW=KVAR/tan(pi)
* Kw=KVA*cos(pi)
* Kw=SQroot(KVAZ^2-(KVAr)^2

I hv a question regarding power factor improvement just
after transformer. I request you to reply me plzz. thank
you sir.
My friend has a small unit of fabrication. in his factory
the main load is a welding machine, lathe machine, grinding
machine. this load is not continuous type. now our
electricity board has installed 16 KVA, 11000/433 V
transformer for our factory. In the energy meter (trivector
meter) at LV side of transformer, i hv seen power factor
value of 0.15 only when only 3 KW load was flowing. Further
electricity board has suggested to install 4 KVAR capacitor
at LV side after energy meter. Now my question is that if
we permanantly install and switch on 4 KVAR capacitor after
energy meter, during some load on transformer and also
without any load on transformer, wht will be the power
factor shown in energy meter?i dont want to get any penalty
by electricity board, so plz suggest me if i can
permanantly install and switch on the 4 kvar capacitor or
not at LV side of transformer just after energy meter?
Thank you again and awaiting for ur positive reply soon.
