In order to better apply time-domain dielectric response technique in non-destructive diagnosis of transformer's aging state, the influences of testing temperature on time-domain dielectric property of oil-paper insulation was investigated. Firstly, the experiments of oil-paper insulation winding model under different testing temperatures were carried out. After then, the integration of time-domain...
The oil-immersed power transformer is the core equipment for energy transmission and distribution power system. Assessing the condition of Oil-paper insulation system accurately is tremendously significant. Polarization and depolarization current measurement (PDC), which is based on the dielectric response, is currently widely used for condition assessment of transformer insulation as non-destructive...
