Arcing horns bushing insulator

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
Bushing insulator arcing horns Arcing horns protect bushings in case of the overvoltage Arcing horns HV Plate Insulator GND

Given:
Relative permittivity of air ε0 = 1,
Relative permittivity of insulator εr = 6,
HV = 6 kV (RMS).

Task:
Calculate electric field stress distribution along the bushing insulator surface and in the spark gap.

Results:
Electric field distribution in the spark gap.
Electric field distribution in the spark gap of arcing horns
