Comments on metal oxide surge arresters surges energy absorption capacity
Conference Record of the 1996 IEEE International Symposium on Electrical Insulation, 2002This paper presents an approach to determine the energy absorption capacity of metal oxide surge arrester resistors. The proposed approach deals with the discharge current peak versus discharge current time relation. A testing method and a statistical evaluation are proposed.

Applying metal-oxide surge arresters on distribution systems
IEEE Transactions on Power Delivery, 1989The primary advantages of a metal-oxide surge arrester over a silicon-carbide surge arrester are identified as the extreme nonlinearity (flatness) of the metal-oxide voltage versus current characteristic and the elimination of the requirement for a series gap and its associated gap sparkover voltage.

Electrothermal model for complete metal-oxide surge arresters
IEE Proceedings - Generation, Transmission and Distribution, 2001A computational, electrothermal model for a complete metal-oxide surge arrester based on the implicit form of the finite-differences method is presented. The model is used to calculate the cooling curve after the application of overvoltages and the temperature variations during standard test.
