Electrostatic simulation of 3 phase cable

QuickField simulation example

This example is prepared by Dariusz Czerwinski

Problem Type
Plane-parallel problem of electrostatics.

Geometry

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.

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