Abstract- An investigation of ferroresonance in a 230-kV transformer is undertaken. Correct modelling of the iron-core losses and the direct magnetic coupling between phases are shown to be important in duplicating field observations. A brute-force time-domain method and an analytical method for displaying margins to ferroresonance on a parameter plane are compared. Following proposed bus modifications, it is shown that loading resistors may now be made switchable.
