Classification: CPC G | IPC G

Claim 13:
14. A method of localizing a partial discharge in or at an electrical component by a test device, the method by the test device comprising:
applying a plurality of voltage signals to the electrical component,
capturing, by at least one antenna, respective electromagnetic waves caused by the partial discharge in the electrical component,
the plurality of voltage signals are applied by iteratively incrementally increasing a voltage signal of the plurality of voltage signals to consider a number of voltage signals among the plurality of voltage signals until an intensity of an electromagnetic wave, from among the respective electromagnetic waves captured by at least one antenna, from among multiple antennas, exceeds a first limit value or the voltage signal reaches a maximum value, to determine the partial discharge,
ascertaining a location of the partial discharge based on the electromagnetic wave captured and on the first limit value, to localize the partial discharge.
