Abstract
An experiment was carried out to diagnose the deterioration of PMMA insulation with a needle void by analyzing partial discharge and the discharge luminescence. It was shown that, by using image analysis of the discharge luminescence, the state of the discharge could be minutely observed. At the early and the intermediate stages of the deterioration, a swarming pulsed microdischarge occurred. After the occurrence of the tree, the discharge magnitude and the number of pulses are rapidly increased, and the correlation of the discharge luminescence and the maximum discharge magnitude is marked.<>
