Abstract :
Infrared temperature measurement technology is becoming increasingly applied in the detection of composite insulator defects. However, most evaluations of the operation condition of the insulators are based solely on the temperature rise without giving consideration to the factors of the environment, especially the temperature and humidity that the composite insulator is in. This paper focuses on the influence of temperature and humidity to temperature rise of the insulator and includes the study of a batch of overheating insulators from a transmission line. Differences are present in infrared temperature test results acquired from both the actual sites and in laboratories. Apart from this, the infrared test results change under various temperature and humidity in laboratory experiments. Therefore, taking consideration of the test environment is important in determining the degree of temperature rise. At last, suggestions on infrared detection are provided to guide testing at actual sites.
