Analysis of Furaldehyde Content of the Oil and its Diagnostic Value for Transformer Ageing

Electrical insulation paper has been aged under controlled conditions. The degradation rates were measured for cotton and Kraft paper in oil at three temperatures, 120-160oC. The furans produced during the ageing process were measured using High Performance Liquid Chromatography. The effect of oxygen and water on the production of furans was investigated. The relationship t Between the furan concentration in tho oil and the change of Degree of Polymerisation of the paper was also examined.
