Answer / pradyumna171

It is the value of cosine angle between voltage and current due to inductive load (legging power factor) i.e the the value of cos 36 degree is 0.8 ( 0.8 cos fi ),cos 26 degree is 0.9 approx.(0.9 cos fi) and so on. It is also calculate by
True power/Apparent power,Resistance/Impedance or conductance/Admittance.here current leg behind voltage And in capacitive load that angle is minimized i.e improving the power factor.

Answer / rishikesh borse

the ratio of the actual electrical power dissipated by an AC circuit to the product of the r.m.s. values of current and voltage. The difference between the two is caused by reactance in the circuit and represents power that does no useful work.

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.
