Porcelain corrugated insulator

QuickField simulation example

Porcelain solid type bushing insulator of sinusoidal shape under nominal conditions.

Problem Type 3D problem of electrostatics.

Geometry

Given
Insulator permittivity 2.2;
High voltage potential HV = 1000 V;
Ground electric potential V0 = 0 V.

Task
Calculate the electric field stress distribution on insulator surface.

Solution
This problem could be simulated as 2D (axisymmetric) or 3D (import). The sinusoidal profile shape is generated in Excel file, that produces the table of coordinates (x,y,z). This table is imported in SOLIDWORKS to create either 3D body or 2D sketch.

Results
