【Abstract】 Currently, some methods have been applied, which mainly include visual method, ultraviolet image method, infrared image method, ultrasonic pulse-echo method, electric field method, hydrophobicity measurement, leakage current measurement, and so on. In this paper, the detecting principles, applicability, advantages and shortcomings of these methods are analyzed. Then, an on-line hydrophobicity detection method based on portable device is brought forward. The device includes hard and software. The on-site tests conducted on some 110 kV and 220 kV transmission lines in central China show that the method is suitable for on-line hydrophobicity detection.更多还原
