the only answer to this question is that the power factor
of load is not known while designing (it is leading or
lagging) so transformers are rated in kVA. The required
size of X-mer depends on the power factor of load connected
to it.

In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
