Partial discharge (PD) measurement is expected to be an effective method for electrical insulation diagnosis and breakdown prediction of the power apparatus. In order to establish the reliable insulation diagnostic techniques, physical mechanism of PD phenomena are required to be clarified. Especially, electronegative gases and gas mixtures are of interest from the viewpoint of high insulation performance due to corona stabilization effect. Although many investigations1,2 have been so far carried out, PD phenomena have not yet been fully understood.
