Abstract :
This paper presents a new method to analyze the three-dimensional (3-D) nonlinear transient eddy currents and losses of an online transformer in a power system under direct current bias. In the method, power system simulation is incorporated with 3-D field computation to obtain the magnetic parameters and the equivalent exciting source of the online transformer.
