Abstract
In this study, it turned out that the magnitude of Partial Discharges(PD) and the emission of Ozone(O3) were in a strong positive relation by performing insulation diagnostic tests on artificially defect high voltage motor stator
windings. In this sense, the O3 measurements can be a powerful index of the insulation deterioration during normal operation especially in case of surface PD activity.
