Abstract

It was discovered that there was prominent interaction among transformer oil moisture content, acid value, furfural content and insulation paper polymerization degree during monitoring of transformer operation. Therefore, insulation paper aging and furfural generation under the action of thermal energy and moisture, insulation paper polymerization degree decline law, change of moisture content in oil and acid value with aging time were studied through laboratory accelerated thermal aging test in the paper. Test results were analyzed. Change and interaction laws of four test items within the thermal aging test cycle were obtained initially, thereby providing reference for detecting furfural content in transformer oil and judging aging degree of solid insulation paper.
