Hello Everyone,

I have to simulate some our Current transformer for a reactive power compensation plant. The problem is I only get the Excitation curves (VxI) from the manufacturer and MATLAB asks for the saturation points (I and phi).

Does anyone know how I can convert the values from the curve I have to the one I need?

Thank you in advance, Bruno

From my experience using Simulink model Nonlinear Transformer, Matlab has no procedure for conversion of nonlinear RMS voltage-current curve to peak flux-current curve.
