Application line regression method in calculate transformer core parameter

Abstract

This paper describes application line regression method to certain the transformer parameter. The calculation involve the internal characteristic of transformer which is approximate as Linier line. Numerical method that used to solve a linier function is the line regression method. To made the equation of transformer is derive from data have been measured. With match equation from equivalent circuit of transformer and line regression equation will obtain the transformer parameter. To plot the internal characteristic from the measurement data and line regression derivation this is help by MATLAB Software.
