WHY DG are rated in KVA or MVA ???., but ALL power plants
are rated in KW or MW.,,?

Answer Posted / vithal k.

Power plant capacity is in MW means ultimately its in terms
of Amps, current and in PF.

Whereas DG is there in KVA means in terms of voltage and
current.

PP is directly connected to Grid and hence directly come in
to the picture with System inductance.. where as DG will
have bounded load and no more Inductive load is there
compared to Grid and hence negligibly considered as 1 (PF=1)

Ultimately in KW terms PF came out of picture and hence DG
rating ar3e normally in KVA.

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...
