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...
