Answer Posted / rajib
KVAR=KW(tan@1-tan@2)
Where, @1= system power factor, @2= desire power factor
For example. 500KW motor has system power factor 0.8 and we want to improve it 0.95
tan@1=tan cos-1(.8)=0.75
tan@2=tan cos-1(.95)=0.3287
KVAR=500(0.75-0.3287)=210.65=210KVAR
and so on

what is zinc diffusion?
I have an existing old MCCB. ABB Model SACE, the rating are: Ue = 660 volts, Iu =1250 Amps, 3 poles, Ith (max) =800 amps at 45 deg C. I need a circuit breaker for my 3 phase motors, 380 volts 60 hz. the supplier required the minimum ampacity of the breaker to be 911 amps. can i use this breaker with rating of Iu =1250 amps but Ith = 800amps maximum?
