Abstract.A location estimation system for online Partial Discharge (PD) detection is proposed as a low-cost approach to real-time condition monitoring, asset management and operation optimization in future smart grid. Some early progress in the development of subsystems (specifically the antenna, radiometer device, PD emulator and PD generator) for a proof-of-principle prototype system is described. The proposed PD Wireless Sensor Network (WSN) uses a novel approach to PD location which obviates the need for synchronization between sensors thereby improving scalability.

Abstract-The work reported here is part of a PhD research relates to the development of a new type of radiometric system applied to detection of partial discharges signals. A simulation model for the radiometric transmission of a partial discharge pulse is presented. The model is based on a replay model, which acts as a source, which is based on real data to simulate the pulses. The structure considers losses due to the free space transmission path and interferences caused by carriers from broadcast transmissions. A receiver, focus of this research, is based on a radiometer structure, which includes an amplifier, a filter and an envelope detector to minimize the necessity of a high sample rate ADC.
