Abstract :
Continuum calculations are used to understand the avalanche growth of electrical current in a composite insulator consisting of an air gap and a solid dielectric. The results show that trapped charge can quench the electrical breakdown. The results are compared with phenomena found in dielectric barrier discharge (DBD) devices.
