POLOPT/ Optim: Module for Free-Form Optimization

Direct Optimization

Case study 1 : Optimization of the shielding electrodes in GCB

• Automatic creation of the shielding electrodes is achieved
• The distance between the contacts being on opposite voltage is reduced for 72%
• On-line control of dielectric criteria guaranties that the breakdown can’t appear for the optimal forms
• The final optimal shape is transferred back to CAD to enable easy manufacturing.
• The experimental validation of the new optimal configuration is done in HV lab.
• The experimental validation has entirely confirmed the simulation / optimization output.

Free-form optimization of the shielding electrodes.Dielectric criteria are on-line checked during the optimization process through the post-processing evaluation of the field lines in order to fulfil the required BIL standard.
