What is the formula to find out the kvar required to
improve the powerfactor from .85 to .99 at 1500kw, 415v.
Answer Posted / habeebm
The KVAR required is:
KVAR=KW(tan@1-tan@2) (where @1=cos-1(p.f1)& @2=cos-1(p.f2)
Therefore,
KVAR=KW {tan[cos-1(p.f1)]-tan[cos-1(p.f2)]}
=KW {tan[cos-1(0.85)]-tan[cos-1(0.99)]}
=KW {tan[31.79]-tan[8.11]}
=KW {0.48}
=1500 {0.48}
=720
Therefore 720 KVAR is required to improve powerfactor from
0.85 to 0.99 for 1500KW load.
