A Study on the Estimations of the Tension of the Overhead Wires Using Data from Acceleration Sensors

One of the important tasks of the distribution system is to operate the distribution system in consideration of the safety. It is also important to minimize and prevent possible failures in the distribution system. In terms of overhead wires, it is necessary to measure the tension of it for the purpose of ensuring safety. However, it is difficult to install sensors for measuring the tension of the overhead wires in the field as there would be huge difficulties to re-install facilities such as existing wires after dismantling them. Thus, it is difficult to manage the risk of overhead wires through tension measurement. To solve and alleviate this problem, this paper proposed and verified a method of attaching an acceleration sensor that does not require dismantling or re-installation of existing facilities to the overhead wires and estimating the tension using the data measured from the sensors. As a result of the verification, it was confirmed that the estimated tension showed a significant level of accuracy with an average of 90.39%, and on the basis of this result, it is expected to contribute to safety management of overhead wires in the future.
