Data and Report from S&T Project 19078: Rotor Installed Corona Mapping of Stator Windings within Large Diameter Hydro Generators

This research utilized near field communication antennas to map partial discharge activity, with slot level resolution, throughout a stator winding of a service aged hydro generator with minimal disassembly of the asset and without the need to remove the rotor. Results suggest that, with further research and development, this method may be a viable replacement for conventional corona probe testing. As a replacement, this method would allow for trending of partial discharge activity in each slot of large stator windings while significantly reducing costs, hazards, and risks associated with obtaining this data, which would be a substantial leap in diagnostic capabilities within the industry.
