reactive power its used creative magnetic field .trmission
line reactive power less then active power(export mode).if
reactive power is higher then active power grid power taken
from generator.

What happen to the transformer if the OLTC frequently used for lower and raise occured 50times daily?
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...
