Development of an Inspection Robot for EHV Power Transmission Line Using Embedded Technology

Abstract

The study is based on monitoring the parameters of High-Voltage transmission lines through various
sensors. 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, sanitation, transportation, and safety. 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 repairs or improvements. However, inspection of high voltage transmission lines is a
very risk operation, as workers must move on the lines several tens of meters above the ground, in very demanding and
stressful conditions. To make this work safer, sometimes the transmission of electricity is interrupted for the inspection
operation. However, this may not be possible always, since it would overcharge other parallel lines. In times of high
demand, such as in summer and winter, the utilities may have to pay hefty fines for the reduction in capability to provide
electricity.Preventive maintenance is the best way to avoid problems with transmission line, by robot detecting them in
an early stage and responding accordingly with action plans for repairs or improvements.
