Abstract
The disclosure relates to a method for partial discharge testing of an insulation component, wherein at least one X-ray pulse is applied to the insulation component, an AC voltage is applied to the insulation component and the partial discharge induced by the at least one X-ray pulse is measured, wherein the dose rate of the at least one X-ray pulse is at least about 10Gray/s. The disclosure relates further to a system for partial discharge testing of an insulation component which includes a flash X-ray source for generating at least one X-ray pulse, an AC voltage source, a voltage sensor, a partial discharge sensor and a partial discharge detection device for evaluating the measured partial discharge.
