Open-circuit fault diagnosis in three-phase induction motor using model-based technique [PDF]
Archives of Electrical Engineering, 2020 The presence of an open-circuit fault subjects a three-phase induction motor to severely unbalanced voltages that may damage the stator windings consecutively causing total shutdown of systems. Unplanned downtime is very costly.
