Partial discharge (PD) activity develops in high voltage transformers due to ageing processes in the insulation system which are totally unavoidable. Moreover, operational overstressing and defects introduced during manufacture can also cause the existence of PD activity. The presence of this activity needs to be identified and treated, otherwise it will lead to further ageing and degradation processes...
Ageing processes typically associated with the dielectric and insulation system occur inside high voltage plant. These unwanted processes may lead to generation of partial discharge (PD) activity and ultimately limit the operational life of the plant. The operational over stressing and defects introduced during manufacture also lead to the existence of PD activity and the source of this activity needs...
In high voltage (H.V.) plant, ageing processes can occur in the insulation system which are totally unavoidable and ultimately limit the operational life of the plant. Ultimately, partial discharge (PD) activity can start to occur at particular points within the insulation system. Operational over stressing and defects introduced during manufacture may also cause PD activity and the presence of this...
Partial discharge (PD) analysis, based on measurement data, assumes that PD signals propagate inside a transformer winding from the PD source to the measurement points. In this paper, signals are injected via an external connection into specific points along the winding of a transformer experimental model. The measurement data obtained using radio frequency current transducers (RFCT) connected to...
