Problem Type
3D-import electrostatics.
Electric permeability of SF6 gas ε = 1;
High voltage U = 100 * √2 kV (amplitude)
Determine the levels of electric field strength.
Geometric model is built in a third-party CAD and imported into QuickField.
There is no field inside the metal conductors, so only gas-insulated insulation is included in the model. On the surface of the conductor an electric potential is set.
For convenience the model is dissected along the plane of symmetry.
