Application of infrared spectroscopy in monitoring the aging process of transformer oil

Infrared spectral technology can detect the trace information in the insulating oil through the infrared spectral information of the oil, so it can be widely used to monitor the quality of oil in recent years. It is found that infrared spectrum has great advantages in monitoring the influence of insulating paper, thermal aging, trace water, insulation paint, high pressure pulse, additives and other factors on transformer oil aging. This paper provides a systematic summary of the application of infrared spectroscopy in the methods of monitoring the aging process of transformer oil.
