Two intersecting conducting planes electric field

electric field between planes, electric field FEA analysis

Two conducting planes intersect at an angle β = 270°. The planes are assumed to be held at potential V. Find the electric field distribution near the corner.

Problem Type:
Plane-parallel problem of electrostatics.

RG 220 coaxial cable insulation Determine the electric field stress distribution in the cable insulation β=270° Air Conductor, V+

Relative permittivity of air ε = 1;
Voltage V = 100 V.

Open space problem is converted to the closed region problem using the "zero potential" boundary far away from the studying object.
