Answer / rakesh kumar

a transformer has no moving parts , there is no rotating
magnetic field in a transformer like the induction motor ,
and hence no torque is is generated to keep one of the
windings in motion.

Answer / karthi

tranformer has no rotating part like rotor and stator..and
no torque produced in it..so transformer is static device..

Answer / chirag jain

because transformer has no moving parts in its
construction,and also in the procedure of transferring
voltage.

Answer / amrish sharma

b,coz it is not a movable device,,,nor it any parts moves
for transfer of voltage,,,

Answer / arunkumar s

Because the transformer works on the principle of mutual
induction.That has no moving parts

Answer / pankaj singh

As transformer doesn't have any moving part responsible for
its action,infact it works on the principle of mutual induction.

Answer / himmat

becozz... trasformer no have moveble paet thats why..

if there are six generators (3 gas CATT, one Jenbacher o1 MW each, and two nos Diesel 01 no 01 mw other 0.65mw EDGs ( say), 3 CAtt gas set have identical pole pitch,01mw EDG and Jenbacher gas Set have different pole pitch, how their power connection can be done to connect a common bus bar during installation. in short, how different pole pitched generators power connection can be done to connect a common busbar system through generators incomer ACBs.
