A new approach to monitor copper sulphide migration in paper oil insulation of transformers
Progressive formation and migration of copper sulphide in paper oil insulation has been studied using Frequency domain spectroscopy and real/imaginary part of complex permittivity. Two specimen configurations namely pigtail sample and laboratory model transformer have been used for understanding the performance of paper oil insulation under conditions of copper corrosion. It is observed that both FDS and permittivity variations with frequency can be used for understanding the progressive migration of copper sulphide.
