Abstract

Based on the microwave radiometry, the brightness temperature of insulator contamination is introduced to the contamination detection with an 8 mm microwave radiometer. And the relation between the brightness temperature and equivalent salt deposit density (ESDD) together with nonsoluble salt deposit density (NSDD) was analyzed by fitting the data from artificial contamination tests under dry and wet conditions, respectively, which obeys the law of power function. The exponent characterizing the influence of ESDD on the brightness temperature is independent of NSDD. And the influence of ESDD on the brightness temperature of contamination is smaller than that of NSDD. Based on the tests and analysis, a model of monitoring system is introduced with radiometer detection.
