Modelling the influence of atmospheric conditions represented by wind, precipitation and air temperature on the intensity of failure and restoration time of medium-voltage power lines

Abstract

The article presents the impact of atmospheric conditions represented by wind, precipitation, and air temperature on the intensity of damage to medium-voltage power lines and their restoration time. It discusses the mechanism of damaging these devices due to the influence of wind, atmospheric precipitation, and high and low temperatures. The method of modelling the relationship between the intensity of failures of power objects and the values of various environmental factors is discussed. The results obtained during many years of research for medium-voltage power lines operated in Polish electric power distribution networks are presented. These studies were conducted independently for lines with uninsulated conductors, semi-insulated conductors, and cable lines.
