Conversion of RMS to Instantaneous Saturation Curve: Inrush Current and Ferroresonance Cases

A method for determination of instantaneous magnetization saturation curve of transformer iron core is presented in this paper. Derived instantaneous saturation curve is incorporated into transformer model applicable in low frequency electromagnetic transient simulations. Developed transformer model is tested on the simple examples of transformer transients such as inrush current and ferroresonace.
