Dielectric surface effects on transient ARCS in lightning arrester devices

Hjalmarson, Harold P.; Pineda, A.C.; Jorgenson, Roy E.; Pasik, Michael F.

Continuum calculations are used to understand the avalanche growth of electrical current in a composite insulator consisting of an air gap and a solid dielectic. The results show that trapped charge can quench the electrical breakdown. The results are compared with phenomena found in dielectric barrier discharge (DBD) devices. © 2011 IEEE.
