The proposed PhD project will study the suitability of the RFI monitoring platform developed by GCU for detecting and monitoring the levels of pollution and contaminants on HV insulators.
RFI monitoring has two significant advantages over existing methodologies for pollution monitoring on HV insulators; 1) it is possible to determine the nature and severity of the PD activity based on the radiated frequency spectrum and the pulse repetition rates at a defined frequency, and 2) it does not require physical connection to the HV insulator or earth lead.
The specific objectives of the project are:
a) Develop a theoretical understanding of the change in electric field distribution across the HV insulator as a function of the contamination type and level.
b) Identify the radiated frequency spectrum and pulse sequence patterns for various levels of surface PD activity on the HV insulator.
c) Obtain an in depth understanding of the relationship between the PD frequency spectrum, the leakage current and the level of contamination.
d) Develop and implement software algorithms that will enable the severity of the PD to be identified and trended based on the frequency spectrum and pulse repetition rates.
