Abstract: The proper maintenance of High-voltage transmission lines is of vital importance, since any problem may result in the interruption of electricity, with many negative impacts to health, transportation and safety and causes a huge loss of capital. Preventive maintenance is the best way to avoid problems with infrastructure, by detecting them in an early stage and responding accordingly with action plans for improvements or repairs. So idea about the Line Inspection bot meets this requirement. It will consist of camera modules; Image Processing techniques are used for detection of faults and cut in conductor, corrosion over conductor or guard ring.
