there are a transformer and a motor. both are connected to
3phase, 415 Volt, 50Hz power supply. Both are working with
induction principles. Then, why, motor is rotating and
transformer is not rotating.

Answer Posted / krishna

Transformer works on the principle magnetic induction.

but transformer having primary and secondary
windings ...which are static ..then how rotation is
possible in transformer????/

coming to induction motor it having primary and secondary
windings ....one of which is a static winding and other is
rotatory winding.
hence rotation is possible due to magnetic action produced
by the mutual induction principle as in tranformer...

In Dyn11 power transformer if any one of the 3 phases connected to earth in star connected side then please explain effect of the current flow in delta connected side of transformer.(In this case if one phase is shorted to ground in star connected side then we observe the current flow in two phases only not three phases in delta connected primary side. Please explain why it is so?)
