Electric stress in the bushing insulator, arcing horns insulation, electric field in the insulation
Arcing horns protect bushings in case of the overvoltage.
Problem Type electrostatics.
Geometry 3D import
Relative permittivity of air ε0 = 1,
Relative permittivity of insulator εr = 6,
HV = 6 kV (RMS).
Calculate electric field stress distribution along the bushing insulator surface and in the spark gap.
