The The Electric Discharge Interface can be used to model electrical discharges in gases (for example, air, SF6, and CO2), liquids (for example, transformer oil, and water), and solids (for example, polyethylene, and rubber), as well as the charge accumulation and relaxation effects at their interfaces. Typical modeling examples are streamer discharges, corona discharges, DBD, and partial discharges. This interface contains predefined discharge models that are ready to use.
