my company total load is 1000kw, 415volt, all load are
inductive load. incoming powerfactor is .8. we want to
have0.95 pf connecting capacitors. so now how much rating of
capacitors we have to connect? show how?

Answer Posted / rman
currently, the load is 0.75MVAR operating at 0.8pf. to enhance it to 0.95pf, the MVAR must be decreased to 0.329MVAR.
Q=0.75-0.329=0.36MVAR
0.36MVAR must be your operating reactive power. therefore your capacitance must be {0.36M/[0.36M/(415*0.95*sqrt(3))]^2*sqrt(3)} which will be your reactance at 0.0969 per phase. also to find the capacitor to be inserted per phase,assuming your frequency is 60Hz, C=(2*pi*60*0.0969)^(-1)
therefore the C=27.37mF

how pt is using
Sir,In our company there are 3 caterpillar make(capacity:(1) 3.3KV,2.5MW(2)3.3KV,2.5MW & (3)3.3KV,1.9MW) & 1 deutz make (capacity:11KV,3.8MW)gas engines utilised,all are running in paralell. There are three transformer utilised,(1) 6.25MVA,3.3KV/22KV,Impedence voltage:6.7% used for two generator,both are 2.5MW(2)5.5MVA,3.3KV/22KV,Impedence voltage:7.2% used for one generator of 2.5MW & (3) 5.5MVA,11KV/22KV,Impedence voltage:7.8% used for one generator of 2.5MW.all generator breakers capacity of 1250Amps. Sir,I want the details of fault level calculation of generator,transformer individually & for whole system. If you require any information from me.feel free for contact me sir.pl.send the answer of my question as the earliest as possible.
