This research intends to prove by experimental work how ferroresonance can occur between generating systems based on a self-excited induction generator and power transformers. Up to four different paths have been tested under different commutation maneuvers. Ferroresonance appearance can unfold into a dangerous state for machinery and personnel. Several over-voltages can be present in the system by a simple delay in one of the poles responsible for grid connection/disconnection.
