Abstract

Photomultiplier tubes (PMT) in combination with flexible liquid light guides and lenses have been tested for partial discharge (PD) detection. The coincidence technique was used to eliminate the random noise of PMTs. Results of PD measurements in two different insulation systems, namely a needle-plane arrangement in air and a ceramic substrate in silicone liquid, are presented and discussed.
