Microcosmic mechanism and correction of moisture effect on furfural diffusion and equilibrium in oil‐paper insulation

High Voltage, 2023
Furfural content in oil is considered as an effective parameter to evaluate the ageing state of oil‐immersed transformers. In previous thermal ageing experiments at 130°C, we found that moisture increment in oil‐paper system makes more furfural ...
