Arcing horns bushing insulator

QuickField simulation example

Arcing horns protect bushings in case of the overvoltage.

Problem Type electrostatics.

Geometry 3D import

Given
Relative permittivity of air ε₀ = 1,
Relative permittivity of insulator ε_r = 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.
