Answer / lakshmi shankar pathak
iron losses r basicaly due to hystresis and eddy currents.
these r constant losses for electrical machne.
these losses r frequency dependent.

Answer / rawat
Iron losses (No load Losses) are depended on your flux density, and frequency/voltage. Simply apply the voltage at LV side which gives rated secondary voltage at HV side (at open circuit). Measure the voltage current and power factor at input side (or simply the input power). Wo=VISin(phi)shall be your no load losses.
