can we use ordinary transformer in place of
autotransformer?give reasons also
Answer Posted / bosky babu
An auto transformer is used where we need the voltage from 0 to the max value. In an ordinary transformer we can only tap the voltages at few points.

current transformer balance the power level on both sides. e.g in case of step up, at secondary side voltage rise but current decrease and vice versa in case of step down transformer. but how this power level remains same in case of current transformer and voltage transformer

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.
