Transformer losses, are copper, iron losses but some times
comes in leakeges. Which some times are negligable.
And mostly, copper losses take alarge portion due to
transformer windings.
kW is for loads, whose losses are normally known to be
caused by heat or I2R, so due to location and the task to be
serviced by atransformer, the power is whole, Apparent
power. As it should meet both inductive, capacitive, and
even resistive equipments in the system.

i have total 8 dg sets for synchronizing and 2 buscoupler,1 sectoin dg no 1,2,3,and 2 sectoin dg no 4,5,6,and last section dg no 7,8 ....if buscupler no 1 and 2 is off mode ..than dg no 1,2,3,will synchroniz of another dg sets?
