SimLab Tutorial Summary: ES3D Streamer in an Insulator

Description

The studied device is an insulator separating two conductors, one at high potential, and another one grounded. The device is in the air.

The aim is to study ionized canals propagation (Streamers propagation) with "Streamer Criterion" Load.



Analysis 1: Streamers propagation

The Streamer criterion tool is used for:
  • Global computation: all ionized canals which can propagate from the selected surface and for the project potentials difference, are displayed. The Streamer having the highest probability to propagate and possibly leading to a breakdown (minimal Streamer inception voltage) is displayed in red. The computation results (numerical values and curves) correspond to this Streamer.
  • Local computation: the Streamer going from the selected point is displayed. The results including the Streamer inception voltage are created


Example access

All files corresponding to this example are accessible in the following link: Tutorial package.

Remarque : The tutorial packaging may evolve with each new version, but not mandatory. The latest version of the tutorial package will automatically work with the most recent release of SimLab.

Example: After installing the SimLab 2025 release, you can find the latest Tuto_2024.zip package. This means that the tutorial has not been updated since 2024 release, that the tutorial does not need to be updated, and that the tutorial still works in 2024.1 release and 2025 release.
