AVTech conducted service project performing partial discharge (PD) measurements in Germany at one of the larger power plants. The reason for AVTEch’s project was the earlier results of transformer diagnostic that needed a follow-up. AVTech’s aim was to verify the earlier findings and, if possible, locate the source of the PD.
WHAT WE DID
The measurements were performed by the AVTech team. The transformer had a rated power of 600 MVA. 45 sets of measurements were recorded covering the high and low voltage sides of the transformer.
