what is the difference between power and distribution
transformer?
Answer Posted / harsha
power means
voltage*current
power t/f(1-phase,3-phase)is designed to change amplitude
of high frequency pulses by the turns ratio and provide
isolation b/wcircuits
distribution transformer is used to change the voltage
levels ex:high to low&low to high
(step up t/f&step down t?f)

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...
