Partial discharge generator
WebAbstract - Partial discharge monitoring is an effective on-line predictive maintenance test for motors and generators at 4160 volt and above, as well as other electrical distribution equipment. The benefits of on- line testing allow for equipment analysis and diagnostics during normal production. WebJul 7, 2024 · In order to monitor the output of the signal generator, it was measured through a VT (with k = 290) and sent to the Picoscope. The transformer, cable and monitoring system were placed in a Faraday cage in order to limit the noise level. ... Fu, M.; Xu, Y.

PD usually begins within voids, cracks, or inclusions within a solid dielectric, at conductor-dielectric interfaces within solid or liquid dielectrics, or in bubbles within liquid dielectrics. Since PDs are limited to only a portion of the insulation, the discharges only partially bridge the distance between electrodes. PD can also occur along the boundary between different insulating materials.

Proper correction for known ... WebPartial discharge can be described as small electrical sparks that occur in stator windings whenever there are small air gaps or voids in or around the insulation. Once sparking occurs, the stator windings start to deteriorate. The larger the void in insulation, the larger the possible discharge resulting in possible machine failure.
