“…The growing needs for the reliability of electricity supply to the population increase the requirements for thermal imaging technology. At the present detection of faults largely depends on the experience of the personnel and has insufficient efficiency [1][2][3][4][5][6][7][8][9][10][11][12].…”

This paper describes a software algorithm for detecting defective insulating structures using infrared images. The defect detection criteria are based on a joint analysis of the mean and standard value of the brightness distribution of a set of insulators. The effectiveness of the developed criteria is substantiated by the results of laboratory tests of a significant number of insulators removed from high-voltage lines according to the results of thermal imaging diagnostics. Simultaneous analysis of thermograms of the same type of insulating structures according to the proposed algorithm is more effective in comparison with the subjective assessment of each of them separately, which was used earlier. In addition, this approach allows to reduce the time of analysis and decision-making based on the results of diagnostics.

“…Along with a large number of advantages, the weighing method has a number of disadvantages, namely: the need to make changes to the linear reinforcement and high cost [12]. In turn, the inclinometric method is reliable, simple and does not require changes to the design of the overhead line, but has errors in measuring the angle of inclination of the sensor (accelerometer) and errors associated with recalculating the angle of inclination due to the force of the conductor tension [7,13].…”

The article substantiates the relevance of the inspection of overhead power lines by determining the mechanical loads of the conductors. The conductor sways under the action of external loads and variable internal mechanical loads. The conductor behaves in span like a pendulum. A model of the harmonic oscillations of the conductor in flight is derived to assess the mechanical loads of the conductor overhead power lines. This mathematical model is based on mathematical models of a flexible thread and a model of a physical pendulum. A conductor is a physical pendulum, where the conductor acts as the body, and in the role of the fixed axis of rotation, a straight line passing through the suspension points of the conductor. The article briefly describes an algorithm for calculating the conductor sag for the case when the conductor suspension points are at the same height. The results obtained using the developed model for calculating the sag of the conductor by its period are compared with the available experimental data. Experimental equipment is described. The error of the method is estimated.
