Abstract
Detecting partial discharge (PD) activity is crucial to establishing the quality and reliability of high voltage insulation systems. This project is concerned with bringing together two very different approaches to the measurement and analysis of PD activity. Conventional measurements to IEC60270 are concerned with quantifying the electrical charge involved. In contrast, radio frequency (RF) techniques essentially respond to the charge dynamics of PD current pulses. Both methods are affected indifferent ways by the physical properties of the PD and the test object in which it occurs.Our research will explore means of combining the two methods to produce a prototype diagnostic tool capable of providing high quality information concerning the location and severity of discharge activity. Application of such a measurement capability will allow manufacturers to increase automation of high voltage testing and users to employ new and more reliable diagnostic tests in evaluating the condition of in-service plant. In addition, fundamental studies of the relationship between the measurements will contribute to the advancement of international standards relating to the detection of PD using RF methods. The work is to be carried out as a collaborative project between the University of Strathclyde and Glasgow Caledonian University, bringing together two research groups with expertise in different but highly complementary fields
