Partial Discharge Inside Solid Dielectrics
Application ID: 143901
The electrical insulation strength of gases is generally much lower than that of solids. Under normal operating conditions, electrical discharges—known as partial discharges—can occur in voids or cracks within a solid dielectric.
This model simulates partial discharges in a spherical air void embedded in a solid insulator under a 50 Hz power frequency. It incorporates detailed charge transport processes coupled with electrostatics, while automatically accounting for surface charge accumulation at the interface. The simulation produces the Phase-Resolved Partial Discharge (PRPD) pattern.
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Tabella delle Funzionalità and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
