Answer Posted / saravanakumar
primary winding,secondary winding and transformer core are
all the main parts of the transformer.
the supply voltage is connected to the primary
winding, the load is connected to the secondary winding and
in the transformer core only the magnetic flux path will b
established..
in power transformers(used for transmit the heavy
voltages to the grid) on load tap changers used.. but in
distribution transformers off circuit tap changers are
used.
there is another type of transformers called auto
transformers in which part of the primary winding used as a
secondary winding.
buccholz relay s used for the transformer protection.

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.
