MOTOR:
When a current carrying conductor is placed inside a
magnetic field then it experiences a torque.This torque
causes rotor of motor to rotate.In case of motor,rotor
conductor carries a current which is in the vicinity of
magnetic field created by current flowing through stator
winding.hence rotor rotates.
TRANSFORMER:
In this case whole magnetic field is confined inside the
transformer core (Except leakage field).But current carrying
conductors (i.e. windings)are wrapped around the core.Thus
conductor is not in the vicinity of magnetic field and hence
no torque is developed.So due to absence of torque (Which is
compulsory for rotation),transformer does not rotate.

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.
