how to calculate the kw, Amps consumed by a capacitor, give me the formula for KVAr into capacitanc..

Answer / pugalenthi.s

Amps can be calculated by = KVAr / (V line to line * 1.732
for three phase.
KW can be calculated by = V * I * 1.732

how to calculate the kw, Amps consumed by a capacitor, give me the formula for KVAr into capacitanc..

Answer / michael

Amp consume by the capacitor simply Q = VIrf
where rf = sin theta, since it is
capacitor so theta = 90 deg
sin 90 = 1
so simple I = Q/V
Q = reactive power
V = voltage
I = current

(KVA)^2 = KW^2 + KVAR^2
since purely capacitiy KW = 0
therefore KVA = KVAR..

NOTE : in a purely capacitive or inductive
real power always Zero
