Aging Evaluation and Online Monitoring of Composite Insulators

Abstract:

To evaluate the aging characteristics and study online monitoring method of composite insulators, four 220kV composite insulators of the same type were tested by visual examination, hydrophobicity tests, infrared thermal imaging tests and scanning electron microscope (SEM) tests. The results show that the infrared thermal imaging tests can effectively detect the broken insulators on-line and the SEM test is feasible to evaluate the aging degree of composite insulators.
