%0 Journal Article %T ASPECTS OF SURGE ARRESTERS¡¯ MAXIMUM OPERATING VOLTAGE CHOICE FOR ELECTRICAL EQUIPMENT INSULATION PROTECTION IN 6-35 KV MAINS %A Yu. N. Shumilov %J Electrical Engineering & Electromechanics %D 2013 %I Kharkiv Polytechnic Institute %X The paper shows that, in 6-35 kV mains, application of a non-linear surge arrester (SA) with the maximum continuous admissible operating voltage which is 10% higher than the mains¡¯ maximum operating voltage results in the SA protection from overheating and subsequent breakdown at nonnormable lifetime of single-phase arc faults. %K non-linear surge arrester %K insulation %K arc fault %U http://eie.khpi.edu.ua/article/view/16935/14608
