Abstract	This article presents results of research on the strength distribution of electric and magnetic fields created by a bus-bar arrangement of a linear disconnector on 110-kV outdoor switchgear (OSG). The research was carried out directly under phase line wires with a small radius and long length going out from the disconnector. The research was carried out for two linear disconnectors of OSG placed far apart from each other. The height above the ground of the bus-bar arrangement of the linear disconnector amounted to 0.5–2 m. For the bus-bar arrangement of linear disconnector placed at a height above the ground of 5 m, experimental studies of magnetic field strength under the middle and outermost phase line wires were carried out. The studies were performed at a distance of 1 m from the linear disconnector for heights above the ground within the range of 0.5–2 m. The parameters of the strength indicators of electric and magnetic fields were determined. Recommendations for location of the strength indicators of electric and magnetic fields are given. The behavior of the strengths of electric and magnetic fields under the bus-bar arrangement of the linear disconnector is determined, and the principle of indication of electric and magnetic fields under the OSG elements is specified.
