Answer Posted / sagar
Q = VIsin(fi)
capacitor current = I = Q/Vsin(fi)
For , 230 v and power factor angle 90 ,then
I = 1/230*sin 90 = 4.32 amp.
If power factor angle is 36.89 (power factor 0.8)
,then
P/Q = kw/KVAR = VIcos(fi)/VIsin(fi)
P/Q = cos(fi)/sin(fi) = Tan(fi)
P = Q tan(fi)
P = 30 tan(36.89) = 30 * 0.75 = 22.5 Kw

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
