    Abstract: PROBLEM TO BE SOLVED: To provide a method and system capable of holding down the starting voltage of partial discharge in partial discharge test of an insulation component. SOLUTION: At least one X-ray pulse 7 is applied to an insulation component 2 by a flash X-ray source 6, and an AC voltage applied to the insulation component 2 by an AC voltage source 5 is measured by a voltage sensor 9. Further, partial discharge induced by the at least one X-ray pulse 7 is measured by a partial discharge sensor 8 and evaluated by a partial discharge detection device 10. A control unit 11 is provided so that the AC voltage source 5, the flash X-ray source 6, and/or the partial discharge detection device 10 are/is controlled or, in particular, controlled in dependence upon the applied AC voltage. It is assumed here that the dose rate of the at least one X-ray pulse 7 is at least 10 -2 Gray/s. COPYRIGHT: (C)2010,JPO&INPIT
