摘要：
The invention relates to a method for partial discharge testing of an insulation component (2), wherein at least one X-ray pulse (7; 13; 14) is applied to the insulation component (2), an AC voltage (12) is applied to the insulation component (2) and the partial discharge induced by the at least one X-ray pulse (7; 13; 14) is measured, wherein the dose rate of the at at least one X-ray pulse (7; 13; 14) is at least 10 -2 Gray/s. The invention relates further to a system (1; 15) for partial discharge testing of an insulation component (2) with a method according to the invention, that comprises a flash X-ray source (6) for generating at least one X-ray pulse, an AC voltage source (5), a voltage sensor (9), a partial discharge sensor (8) and a partial discharge detection apparatus (10) for evaluating the measured partial discharge.
