What the capacitor Current formula?, For 1 KVAr how amps
its required? for using the KVAr for boosting the PF Design
Calculation.( Eg: for 30 KVAr required how many KW?)

Answer Posted / mehmud ahmed

Hi every one how are you
if u need to know three phase capacitor rating than

I= kvar x 1000 / V x 1.73

Example:

i have 25 Kvar capacitor and line to line voltage is 440. i want to know current rating of capacitor

I = KVAR x 1000 / V x 1.73
I = 25 x 1000 / 440 x 1.73
I = 25000 / 762.08
I = 32.80 Amp

So my Ans is (32.80 Amp)

Is This Answer Correct ?    70 Yes 3 No
