    Abstract

    On-line monitoring of high-voltage electrical equipment (HV-EE) aiming to detect faults effectively has become crucial to avoid serious accidents. Moreover, highly reliable power supplies are the key component for the wireless sensors equipped in such on-line monitoring systems. Therefore, in this paper, the wireless power supply via coupled magnetic resonance (MR-WPS) is proposed for powering the wireless sensor and the associated wireless sensor solution is also proposed. The key specifications of the MR-WPS working in switchgear cabinet with a harsh operation environment are analyzed and determined. Design of these key parameters of the coupled magnetic resonant unit (CMRU) in MR-WPS is provided as well as the method of optimizing the resonant windings is given. Finally, a prototype is built and tested. The experimental results are presented in order to show that sufficient and reliable power is able to be delivered to the wireless sensor through the designed MR-WPS, and therefore the theoretical analysis and design is verified.
