摘要: Performance and life of any transformer depend entirely on the dielectric property insulation used. In recent times, ester oil is replacing mineral oil. this paper, effects electrical aging in presence pressboard as a barrier between high voltage ground electrode studied. Corona inception has been used to understand variation characteristics with time. induces degradation resulting formation carbonaceous particles. This leads an increase concentration occurring due particles suspension different size. To analyze variation, dynamic light scattering analysis carried out samples. It was observed that fluorescent nature change its fluorescence characteristics. monitor characterize degradation, fluorescence-based obtain data 3D excitation emission matrix.
