Answer Posted / g.l.a ites
the heat generated in a winding as well as the eddy current
losses generated in a transformer core depend on the current
only, regardless of whether it aligns with the voltage or
not. Therefore the heat is always proportional to the square
of the current amplitude, irrespective of the phase angle
(the shift between voltage and current). So a transformer
has to be rated (and selected) by apparent power
