Hi
If we have dc hysteresis loop from the manufacturer , how to plot the
exciation current in time domain for 50 Hz supply voltage for a
transformer
please consider this

A specific DC hysteresis loop is not sufficient as it is really only of
interest when you have a loop for a given maximum flux density.
At higher or lower flux densities the hysteresis loop changes. However, you
can get an approximation to the AC magnetization curve for a given material
by taking the midline of the hysteresis loop. and scaling to Bmax as a
function of Hrms for a sine wave (Vrms =4.44fNABmax for a sinusoid and the
corresponding current. It is easier to simply get this information directly
from the manufacturer.
The area of the loop at a given Bmax (not given by a specific B-H curve as
there will be an infinite nest of curves depending on the Bmax will give the
hysteresis loss per cycle but as there are associated eddy current losses,
again it is easier (and necessary) to go back to the manufacturer to get
this data.
