if our load in 3 phase circuit is 4000 amp. calculate the capacity of capacitor panel if line power factor is.80 .
Answer / aditya karkar
182.25kvar capacity of capacitor needed.
solution= IL:4000A V:440V COS@1=.8
SO FIND REAL POWER P.
THEN PUT IT IN Qnet=P(tan@1-tan@2)
we have to make pf 1.so take @2=0
