Gas-insulated high-voltage conductor

QuickField simulation example

Connection of two shielded gas-insulated 100 kV lines.

Problem Type
3D-import electrostatics.

Geometry

Given
Electric permeability of SF₆ gas ε = 1;
High voltage U = 100 * √2 kV (amplitude)

Task
Determine the levels of electric field strength.

Solution
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.

Results

Electric field intensity distribution (SF₆ gas electrical strength 89 kV/cm is not exceeded):
