摘要：
The paper presents advanced diagnostic methods of transformer bushings. There are given results of temperature distribution modeling inside bushings' cores and the analysis of ageing influence on dielectric response of RIP type bushing model, based on the FDS and RVM characteristics. Thermal ageing of RIP bushing model causes the shift of FDS curves into higher frequencies, whereas deterioration products lead to appearance of additional relaxation in high frequency range. (Diagnostics of thermal aging of transformer bushings with solid insulation).
