Arcing horns bushing insulator
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.
Electric field distribution in the spark gap:
