Abstract :
Insulation degradation of high voltage equipment has been one of the major concerns of electricity supply authorities. Amongst the many indicators that can be used to assess the insulation condition of high voltage equipment, partial discharge testing has been one of the most effective diagnostic tools for monitoring the condition of electrical insulation. A new detector has been developed for the measurement of partial discharges in high voltage equipment using radio transmission techniques. Experiments carried out in the laboratory have shown that the new detector has many advantages over the conventional PD detectors. It is believed that this is initial in the PD detection area in the world
