Electrostatic simulation of 3 phase cable

Problem Type:

Plane-parallel problem of electrostatics.

Geometry:

3-phase cable model

The diameter of the cable with insulation is 20mm (for all cables).
The insulation thickness is 2 mm.

Given:

Relative permittivity of individual insulation ε = 3.3;
Relative permittivity of common insulation ε = 3;
Voltage applied U_A = 9.8 kV, U_B = -4.9 kV, U_C = -4.9 kV.

Problem:

Determine the field strength, potential in cable and in insulation.

Results:
