any machine basic working priciple is FARADAYS LAWS of
electro magnetic induction:
1st law:when ever a conductor cuts a magnetic flux an EMF is
induced dyanamically in the conductor.
2nd law:induced emf proportional to flux linkages(N,rate of
change of flux).
based on 1stlaw emf induced in transformer.
stepdown:as secondary turns are low flux linkages is less
hence induced emf is low in secondary camored to primery.
stepup:as secondry turns are high flux linkages is large
hence induced emf is high in secondary camored to primery.

step down:as secondary turns are low flux linkages is less
hence induced emf is low in secondary compere to primery.

step up:as secondary turns are high flux linkages is large
hence induced emf is high in secondary compere to primery.

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.
