Popis: 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.
