Abstract
In the high voltage domain, the Corona discharge represents one of the most disturbing problems for the companies that transport electricity. Corona discharge is an electrical discharge brought on by the ionization of a fluid surrounding a conductor that is electrically energized. To combat this phenomenon it is necessary to keep high voltage power lines under surveillance and try to maintain losses at a reasonable value. The best manner to do this thing is by using a fixed-wing unmanned aircraft vehicle having on board the necessary sensors for detecting Corona discharge. In this paper we will focus on extracting and detecting high voltage lines from the images received from an UAV which will be analyzed using a number ofMATLAB functions. To detect lines into an image the Radon transformwill be used which is an integral transform that maps a function to its integrals over lines.
