Abstract
This paper introduces the principle of power transformer insulation aging and the current commonly used detection methods and their limitations of transformer insulation condition, subsequently introduces an on-site non-destructive detection method(polarization spectrum analysis method), which has the advantages of strong anti-interference and large amount of state. Based on the test of the polarization spectrum residual voltage peak value, the center time constant and the initial slope of the curve to analyze the insulation condition of the transformer. Study the relationship between the characteristic parameter value of the polarization spectrum and the moisture content, the temperature value, the service life of the transformer. And verify the validity of the polarization spectrum analysis technology through absorption ratio test. The results of the test are consistent with the results of polarization spectrum analysis technique.关键词
