Abstract :
Summary form only given. A technique to compute the magnetic nonlinear transients of a transformer is suggested. The technique is firstly composed of measuring the multiple L(i) characteristics represented by the relations of coil current and differential inductance corresponding to each part of the B-H curves of the transformer. Secondly, it is composed of subjecting each L(i) characteristic separately by current slope and current history to the differential equations which describe the circuit operation. This technique proved to be effective.
