EM field effects on the surface of polluted HV insulators
… is essential to design insulation levels. Discharges on the surface of polymeric insulators are one of the ageing mechanisms responsible for eventual failure. In this thesis, we examine water droplets on insulator surfaces. Chapter 1 discusses pollution on the surface of high voltage …

Signal processing techniques for on-line partial discharge monitoring of high voltage electrical machines.
… and can be characterised by an increase in partial discharge activity over time. This activity can be measured using a well-documented, non-invasive technique. However, current analyses rely on experts visually interpreting results, and making judgements based upon their knowledge and …

Electrical breakdown and structural characterization in synthetic resins using optical techniques
… charge recombination model. Type B; with microdischarges as a prelude to tree propagation and Type C; associated with the conventional partial discharge activity in growing tree channels. Electrical tree initiation follows slow material degradation and debonding of the metal/polymer interface …
