Abstract
The operation of energy transmission lines with high efficiency without failure has great importance in today's electricity-dependent world. Problems that may occur in electricity transmission lines are failure cause of many operations not only industrial but also daily life. One of the most important causes of the problems encountered in power lines is the change in the amount of sagging. The change of sagging amount causes line breaks and losing energy efficiency. This problem, which is frequently encountered due to seasonal and climatic changes, is one of the major problems of continuity in the power line. The calculation of sag contains uncertain and variable parameters that can change seasonally, climatically and/or structurally such as weight per unit length of the conductor, the horizontal component of tension, total tension, etc. In this case, it is difficult to calculate a precise and reliable sag amount. The sagging of power lines is generally calculated theoretically or measured on-site by the personnel in charge. In this study, a new approach is presented to measure the sag amount by using sensor data of a power line inspection robot, precisely and reliably. The inspection robot moving on the power line can be remotely controlled and send sensor data. The sagging is measured with an error of less than 2 percent in the laboratory test field by using this technique.
Highlights
Overhead lines are the backbones of every electrical power transmission and distribution system [1]
The lines carried by the poles in the energy transmission lines play the most significant role in the transportation of energy from the power generation facilities to the end-users [2]–[4]
DATA RETRIEVAL AND PROCESSING While driving on the line, wireless data was continuously received from the robot
Summary
Overhead lines are the backbones of every electrical power transmission and distribution system [1]. There are various technical procedures in transporting energy from power stations to end-users These procedures are studied both electrically and mechanically. The energy produced in power plants should be delivered to users and cities with the shortest distance Procedures such as renting or purchasing the land on which electricity poles will be located are made at the planning stage. Along with all these general rules, the length, diameter, and mechanical and electrical properties of the electricity transmission line should be determined separately [20] All these parameters are determined by international standards, each country differs according to its climate conditions, electricity network structure, and the experience of expert personnel.
