Analytical indicators of dynamics of technological failures of 0.4-110 kV overhead lines

Reliable information on quantitative indicators of reliability makes it possible to identify bottlenecks in the system of operational maintenance of rural power grids and to outline measures for its improvement. One of the characteristics of reliability of electric networks is the number of technological violations (TN), which include emergency, planned, consumer, and urgent discon-nections in the line. Assessment of changes in the quantitative values of technological failures al-lows us to identify trends in the dynamics of TN and take preventive measures to reduce their number. The paper defines analytical indicators of the dynamics of technological violations of 0,4-110 kV overhead lines, such as basic absolute growth and growth rate, chain absolute growth and growth rate, growth rate and increase in the number of TN, other indicators that allow to assess the situation with the number of TN in the studied networks.
