Abstract

After years of grid use, composite insulators in electric power systems are subject to varying degrees of aging, including pulverization, elasticity, and hydrophobic degradation. The current nuclear magnetic resonance relaxation spectroscopy detection methods struggle to accurately reflect the specificity among insulators with various service lives. In this study, the aging state of several composite insulators was determined using an NMR relaxation spectrum analyzer with the same sequence control key parameters. The distinctive quantities of the aging degree detection were found, and the appropriate magnet temperature for measurement was investigated. The results demonstrate that the height and area of the wave spectrum can effectively reflect the aging degree of insulators, and the sensitivity and variability of detection results among different insulators can be best reflected at a magnetic temperature of 32 ℃.
