Paper Abstract
Presently electricity utilities make use of a number of inspection tools to survey their transmission lines and electrical
distribution equipment. Mobile robot capable of crossing obstacles is developed on overhead ground wires. A
teleoperated robot with cameras realizes inspection and maintenance tasks on power transmission line. This paper
examines the possibility of remote detection of defective devices on power transmission lines. Infrared, visible and
ultraviolet cameras are the latest visual diagnostic tools available to utilities to identify potential failures on electrical
equipment. Infrared cameras are used to collect images related to temperature differences that arise on components such
as compression splices and insulators. The clever analysis of thermograms will then reveal possible defects. Corona
effects and arcing are symptomatic of certain types of defects on insulators, line spacers, and conductors, etc. These
possible defects can be detected by the ultraviolet. As new imaging technologies were developed, line inspectors began
employing infrared and ultraviolet imaging to locate hot spots and electrical discharges. This paper highlights the design
and development a inspection robot with cameras which combine ultraviolet, infrared and visual imaging techniques for
advanced diagnostic inspections. A novel inspection robot was designed to inspect the 500KV power transmission lines.
Results of experiments demonstrate that the robot can be applied to execute the navigation and inspection tasks.
