Overhead Lines Online Monitoring Using in the Condition Power Grids

The article analyzes various systems for monitoring the condition of high-voltage overhead power transmission lines. The problem of using online monitoring systems for the state of electrical networks is currently relevant. It is known that electric networks with a voltage of 10–500 kV are significantly worn out and it is necessary to improve monitoring systems to prevent the development of possible accidents. Possible causes of failures of overhead power transmission lines are considered. The conducted analysis of accidents in electric networks with a voltage of 10, 110, 500 kV shows that there is a large number of failures of power transmission lines, which could be avoided by implementing systems for monitoring the condition of electric networks. Currently, there is an urgent issue of digitalization of production, a system of integrated digital control over objects distributed over a large area, such as overhead power lines. The introduction of a device for operational monitoring of the technical condition of high-voltage power transmission lines “SMART wire” is considered, the advantages of this device are indicated.
