Background

In the power system, a plurality of power grid elements are located outdoors and are greatly influenced by the external environment, so that the performance of the power grid elements is gradually deteriorated, and the use value is finally lost. The traditional aging tester mainly adopts infrared spectrum, ultraviolet spectrum, photoelectron spectrum and transmission electron microscope to test fluorescence intensity, and judges the aging degree through spectral characteristics. When the power grid element is aged and damaged, the power grid element is difficult to test quickly and accurately by using the spectrum. The rough and uneven surface of the element makes the test result difficult to avoid certain error, and the ultraviolet ray has the defect of accelerated aging.
