A new method to identify fault current and inrush current on transformer byJiles-Atherton model

This paper proposes a new method to detect transformer inside incipientfault current using transformer internal parameters to determine the insidestructure of transformer at good condition or bad. A transformer model wasestablished by Jiles-Atherton theory using measured voltage and current and theinitial parameters which were found using Genetic Algorithm (GA). Then,transformer internal parameters k and c can be estimated using Simplex method toeasily differentiate inrush currents and incipient fault currents. ICIC International
