Answer Posted / swpan kumar bhowmik
As seen, Cu loss of a transformer depends on current and
iron loss on voltage. Hence, total transformer loss depends
on volt-ampere (VA) and not on phase angle between voltage
and current i.e. it is independent of load power factor.
That is why rating of transformer is in kVA and not in kW.

how does the terminal voltage of transmission lines increase when a capacitor is connected???? This happens not only in transmission lines but also in all circuits. How??? When a capacitor is connected in a transmission line, capacitor also takes energy from the same supply. But how is it able to increase the terminal voltage??? Practically What sequence of events happen during increase in voltage???
