CT Saturation Plots

(OP)
Does anyone have an excel spreadsheet for plotting saturation curves for ct's?

RE: CT Saturation Plots

I don't have anything special - I just enter the measured currents and voltages as pairs of points and do an X-Y plot.  If you want to convert to B-H curve from V-I, you would have to know something about the design flux density core size, shape, number of turns etc, and use the standard transformer equations (V=4.44NABetc stuff).
