Tranformer windings are insulated copper wires and are
designed to carry a particular amount of current(depending
on the size/diameter/cross-sectional area of the
wire).Beyond this current the windings will get damaged due
to overheat. The current that flows through these windings
is dependent on the load connected to the secondary of the
transformer. Both active and reactive portions of the
current contribute to the current flowing through the
transformer windings. Thus the total current is the
limiting factor. Moreover, the insulation of the
transformer windings determine the max voltage that it can
support. Thus, the voltage and the current determine the
capacity of the transformer. this product in KVA defines
the transformer capacity. KWatts is the active power and is
lower than the KVA by a factor called pf(power factor).
Where Watts = Volts X Amperes X pf.
