To ensure the  preservation of  maximum energy and power we designed and manufacture  the automatic power factor correction panel which can improve the system power factor from poor to the target value  in AC power distribution system by reducing the circuit loss while increase  and improving the power output of the transformer.

Capacitor bank range :

i.    100 KVAR
ii.    150 KVAR
iii.    200 KVAR
iv.    250 KVAR
v.    300 KVAR
vi.    350 KVAR
vii.    400 KVAR
viii.    450 KVAR
ix.    500 KVAR
x.    550 KVAR
xi.    600 KVAR

To determine the required capacitor bank ratings here is one sample
of our calculation  using simple  equations.
a.    Determining the required  capacitor bank rating to improve  PF
From cosØ  to cosØ̍  (from cosØ = 0.85 to cosØ1 = 0.95)

Qc = Q – Q1 = P tanØ – P tanØ1 = P (0.62 – 0.33) = 0.29 P

Where:
Q : reactive power before compensation
Q1: reactive power after compensation
Qc: reactive power produced by the capacitor bank
cosØ: power factor before compensation
cosØ1: power factor after compensation

Considering of  1600 KVA load as sample  the capacitor bank should be   able to  produce a

reactive power of:

 Qc = 1600 x 0.85 x 0.29 = 394.4 kVAr

The rating of the capacitor bank should be 400 kVAr in 8 steps of 50kVAr.
