The power consumed depends upon p.f. or say power
consumed is Energy Input/ P.F.
The electrical energy reqd by system is thus sum of
product of Total power reqd & power factor of each load.
Basiclly Transformers & Generators are energy devices.
They supply electrical energy to various loads which
consume power. The unit of electrical energy is VA or KVA
or MVA

What are the relays in ACB and VCB
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...
