4.in conclusion
According to the above test results, it can be seen that:
ATR3110-785-35: It can measure the Raman characteristic peak of insulating oil, and the peak is obvious. And the insulating oil strength B>C>A can be obtained through the graph. However, large fluorescent packets appeared when testing the insulating paper, and there were no obvious characteristic peaks, so ATR8300-1064 was used to test the insulating paper.
ATR8300-1064: It can measure the Raman characteristic peaks of insulating paper, and the peaks are obvious. And through the spectrum, it can be concluded that the strength of the insulating paper is D>B>C>A. But the Raman characteristic peak of the insulating oil cannot be measured, and the ATR6600-1064 is used to test the insulating oil
ATR6600-1064: It can measure the Raman characteristic peaks of insulating oil, and the peaks are obvious. And the insulating oil strength B>C>A can be obtained through the graph.
