I dont know in which angle you are asking this question
because transformer is not exporting & importing power but
for impoting & exporting power in a power plant we are
using same transformer.
Most of the pick load plants ( e.g. DIESEL PLANTs ) became
ideal or off in normal hours ( not in peak time )and this
time they are purchasing electricity from the electricity
board for plant's inside supply purpose. This time the
transformer in side the substation which attached to the
plant receiving power from out side feeder. The diesel
plant has to pay electricity bill for the receiving energy.
At peak hours diesel plant started to run & when the
voltage, phase, frequency etc. of alternator are
synchronized then throw the load to the out put feeders
through the transformers. Now the diesel plant is exporting
the power to the electricity board through transformer.

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...
