This paper discusses the reverse action that the secondary voltage of a transformer is pulled down when the tap position of on-load tap changer is raised to increase the secondary voltage. A dynamic model of an induction motor is adopted as a load model simulating this king of reverse action during voltage collapse. The transient mechanisms of the reverse action are analyzed by using P-V curves.
