The important feature of solid insulation aging of an oil-immersed transformer is the furfural generated due to splitting of insulation paper.By monitoring the content of furfural in oil
the aging degree of the insulation paper in transformer can be effectively estimated.Therefore
in this paper
the infrared spectral analysis of furfural in oil is described
and an on-line monitoring system for aging of transformer insulation is designed based on DSP and the infrared spectral analysis of furfural in oil.The system’s structure
