Claim 8:
9. A test device to localize a partial discharge in or at an electrical component, the test device comprising:
multiple antennas respectively capturing electromagnetic waves caused by the partial discharge in the electrical component, the multiple antennas positioned in a set environment around the electrical component,
a control unit configured to,
apply a plurality of voltage signals to the electrical component,
the plurality of voltage signals applied by iteratively incrementally increasing a voltage signal, from among the plurality of voltage signals, to consider a number of voltage signals, from among the plurality of voltage signals, until an intensity of an electromagnetic wave, from among the electromagnetic waves respectively captured by the multiple antennas, exceeds a first limit value, or the voltage signal reaches a maximum value, to determine the partial discharge, and

depending on the electromagnetic wave captured and the first limit value, ascertain a location of the partial discharge for localization.
