Abstract
Defects of high-voltage transmission lines are often accompanied with corona discharge; and corona discharge would produce ultraviolet. Based on this principle, the UV imager can be used in detecting the defect. Electric field strength is the main factor affecting the corona discharge, which is determined by power-supply and experimental model. In this paper, UV measurement of different defects was studied, and the effect of Applied-voltage on corona discharge of defects was acquired. A quadratic relationship exists between the UV strength produced by corona discharge and applied voltage. The quadratic coefficient A is between 0.31~0.37, which is increase with the length increasing at the experimental conditions in this paper.
