Answer / sanjay gonsalves

for 2.5HP 1KVAR is required

Answer / kapil

Requd. KVAR = Running KW*{tan angle (OF running Load)- tan
angle (of P.F. Requried)}

Answer / ganesh

Current x 0.43

Answer / serv omania

12% of HP

Answer / dharmvir

nearly 1/4.5 of the hp and 1/3 of kw

Answer / himanshu

Motor is an inductive load so it is consuming
active power that depends on its load and
reactive power that is consumed by motor to set up its
magnetic field it is constant so we should connect a
capacitor which consumes the negative reactive power
according to p.f. correction requirement.

Answer / santosh

Approx. one third of HP rating of 3ph motor is kvar of
capacitor required.

Answer / rajnikant

First convert HP into KW.
1HP = 746 KW

Then assuming 0.8 powerfactor of motor,calculate KVA

KVA = KW x powerfactor

now calculate kvar by using following

KVAR = square root of (square of kw - squre of kva)

Answer / pankaj malhotra

For 100 HP load kVAR required will be half i.e 50 kVAR. If
you go for proper calculation, ans would be closer.

Why does inductive loads consume KVARs?

In a d.c circuit, if current and resistance are known, power (P=I*I*R) can be determined. This relationship also applied to an a.c circuit. Comment the reason for this.
