dc.descriptionThe thesis also investigated the use of the FBGST multi-physical sensing feature for extracting simultaneous thermal and mechanical information of rotary components for condition monitoring purposes. It is shown that a single FBG embedded in a bearing or rotor structure can enable simultaneous understanding of component’s thermal and mechanical operating conditions, and thus improved understanding of their health status.
dc.description.abstractABSTRACT This thesis reports an investigation of the design, development, implementation and use of in-situ thermal sensing systems utilising Fibre Bragg Grating Sensing Technology (FBGST) for low voltage electric machine (LVEM) thermal condition monitoring applications. The thesis first investigated the key design and operational features of the in situ FBG temperature sensor for thermal hot spot monitoring in stand-alone prototype random wound components. Vital sensing aspects such as the sensor characterisation, packaging material choice, in-situ calibration requirements, use of multiplexing for distributed sensing, the installation procedure and the thermal measurement sensitivity to machine vibration were investigated. The reported findings enable a much improved understanding of the performance implications of embedded FBG sensor design features and the attainable in-situ hot spot thermal monitoring performance in random wound coils. It is shown that reliable, improved fidelity information on the coil’s thermal status can be obtained from application of wound coil embedded FBG thermal sensing systems.
