Partial Discharge (PD) measurement and characterization provide vital information on insulation condition, different aspects of insulation ageing useful for equipment integrity verification and diagnosis. The work demonstrates standard test methods which employs capture of PD parameters with the aid of discharge detector. This paper investigates on the voltage amplitude at which PD of a specifi...

The breakdown of the dry-type reactor induced by being exposed to moisture needs be further explored. For this purpose, as common insulating films in reactor, PET and PI were targeted investigate effects atmospheric hydrothermal aging on microstructure, thermal stability, mechanical properties films. As result aging, moisture-based degradation obviously occurred surface both films, even at a lo...

Methanol is regarded as an available indicator to analyze the aging condition of cellulose insulation. However, diffusion mechanism methanol molecules in paper-oil insulation system still unclear, since it cannot be explored by using only experiments. Given this issue, molecular dynamics simulations were performed investigate molecules. In current work, mean square displacement during process w...
