Answer Posted / guest
transformer losses can be found by doing open circuit test
and short circuit test
open circuit test gives the core losses
short circuit test gives the copper losses
note in open circuit test the lv side is given supply and
in short circuit test the hv side is given supply
the iron losses can be reduced by providing laminations of
thinner dimension and using c.r.g.o sheet for laminations
the copper losses depend on the winding resistance which
increases due to heat can be reduced by providing
sufficient cooling to the winding.
