Standardization of pollution testing of metal oxide surge arresters (MOA) is being attempted by diflerent research groups throughout the world through field tests and laboratory investigations. The non-uniform wet contamination method of ANSI standard C 62.11, 1987, which is reported to have good re
## Abstract Electrical devices are protected against overvoltages by the usage of metal oxide surge arresters. The issue of the paper is an analysis of overvoltage risks of internal insulation systems of transformers protected by such arresters. The analysis is based on the results of computer simu
