Answer Posted / senthil kumar.a
transformer has two major losses one is copper loss it
depends upon the current , the current unit is Amps ans the
core loss depends upon the voltage it unit is Voltage, so
VA the k mantion for the capacity
why transformer capacity not say in KW?
becaz watts is unit of power already we know the formula of
power, it is current x voltage x cos phi. but the two
losses not depends upon the power factor, incase we r say
in KW it makes a error in calculation. because the KW
include the power factor. I hope that it is correct upto my
knowledge only
