MEASURING DEVICE, AND METHOD FOR LOCATING A PARTIAL DISCHARGE

摘要

The invention relates to a device and a method for locating partial discharges in a conductor rod (3) of a dynamo-electric machine (1), said conductor rod (3) being provided with an exterior electrical insulation. According to the invention, a first (5) and a second (6) sensor are embodied so as to detect a signal which is generated by the partial discharge and spreads along the conductor rod (3). Said first (5) and second (6) sensor are disposed at a distance (l) from each other on the conductor rod (3) in order to emit a partial discharge output signal (42, 43) that represents a specific moment of detection. The partial discharge output signals (42, 43) of the first (5) and second (6) sensor are fed to an evaluation unit (44) which is embodied so as to locate the partial discharge on the conductor rod (3).
