Abstract
An algorithm is presented for the computation of the saturation charac teristics of transformer iron cores based on supplied conventional V(r ms)-I(rms) curves and no-load losses at rated frequency. Laboratory me asurements on a steel sample were carried out. It is shown that the ir on core losses are a nonlinear function of the applied voltage. Taking these losses into account improves the nonlinear flux-current charact eristic.
