A change-detection algorithm for short-circuit fault detection in closed-loop AC drives [PDF]
This paper deals with an on-line method for turn-to-turn short-circuit fault detection in low-voltage permanent-magnet synchronous machine drives. Due to the closed-loop control, the fault effects are reflected in the voltage.
