The persistence and usage of electricity – since its discovery – is dynamically increasing. The importance of its' usage is a determining element of the evolution of the society and the economy.

In the view of the importance of this challenge I considered to pay my attention to the terms of the uninterrupted supply of electricity. Such as the prevention of the emerging malfunctions and the possibilities to increase the reliability of the distribution process.

At the beginning of my thesis I describe the tasks and construction of the main parts of the transmission line, such as the pylons, the conductors and the ground wires. After that I summarize the most common damages and their root causes.

In the diagnostic section I describe the detection methods of the defective components, namely detection from the ground and from the air. I also write about the possibilities and solutions which are targeted for improvement of the fault detection in order to minimize the losses provoked by the break of the electricity supply continuity.

After introducing the different diagnostic methods, I explain one of them briefly, which has – in my opinion – the most potential, namely the robot applied diagnostics. I describe the worldwide reached achievements in this field. In order to point out the successes and potentiality of the robots, I write about the ones which are already in use.

In the last chapter I introduce the robot that I built in the semester. The robot is able to diagnose the power lines. The purpose of the construction was to experience the difficulty and challenge of the development. I received a lot of experience, and the experiments made me certain about the utility of the robotics applications for power line inspection. Hopefully I can improve my knowledge on this field in the future.
