要約(日本語): To analyze the surface and space charge propagations with a floated lossy medium, we have developed a fully coupled finite element model including a suitable boundary condition resulting from the migration-Ohmic dielectric modeling. Until now, there have been frequently reported for discharge simulation in the air without any obstacle in the discharge column. However, the real electric apparatus contains various electric structures such as floated conductive media. To verify our numerical model, first, the migration-Ohmic model has been tested with one carrier system with a charge injection mechanism. The critical angle which limits the charge amount adhering to the surface and the tendency of space charge propagation were successfully compared while adjusting the amount of injected charge
