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.

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...

Which operates faster? whicg one is popular in Indian Market and why? 2)Define SCPD. What is type2 coodination? 3)Why the contactor rating is higher for the fuseless selection than for fuse selection? whether the ratinf of SFU or MCCB remains the same in both the cases? 4)If the HP rating is known then can you calculate the ratings of L.V Switchgear(SFU/MCCB, contactor, OLR) without using the selection chart?
