Localizing Turn to Turn Short Circuit in HEV’s Machine Using Thermal Finite Element Model

Hybrid electric vehicles (HEVs) are becoming widely spread due to their advantages when talking about power consumption and pollution free environment. The main concern of HEVs is their reliability and availability; hence, the ability to detect malfunction at early stage or before it occurs is a must. To assure their proper operation, most researches in the field of fault detection, head toward prognosis being the best alternative among the available maintenance strategies and actions. In this paper, the thermal finite element model will be used to detect and localize the presence of turn to turn short circuit at its early stage. A suggestion for localizing temperature sensors, in the electrical machine, will be presented.
