Answer Posted / naresh
we know that in case of a transformer ,the emf induced in
the secondary is proportional to the alternating flux
flowing in the primary of the transformer.
so alternating flux is produced by supplying alternating
voltage to the primary of the transformer.
if in case a dc voltage is applied ,the flux flowing
through the primary of the transformer remains constant.
therefore emf induced in the secondary is zero.
therefore no emf is induced in the coil.

generally in LT and MV motors we are using 3.5Coresx16,25,35,50 etc cable for supply.although motors is earthed at two point and having all protection.then why we are using that 1/2 core for earthing the motors.while in HT cable we are using only 3core cable for motor supply.generally lt and mv motors are delta connected and ht motors having star connection.whethere it is having any relation with winding connection( star or delta).all motors i am talking about are dol only.can anybody solve my confusion.thanks...
