摘要：
The purpose of this study is the fault discrimination of the transformer that supplies power in demand. In this study, the correlation between the light transmittance of the insulating oil and dielectric breakdown was used to the fault discrimination of the transformer. In this study, the light sources of various wavelengths were compared, and it was shown in the paper that the selected 520 nm light sources can clearly diagnose the deterioration state. In addition, in order to evaluate the total dielectric breakdown of the insulating oil, research was conducted through various samples through the collection of insulating oil samples and acceleration deterioration tests of the used transformer. It is believed that the diagnostic method for the state of the transformer using the light transmittance of the insulating oil proposed through this study can help secure the reliability and economy of the power facility.
