IEC 60099-6: 2019 applies to non-linear metal-oxide resistor type surge arresters with spark gaps designed to limit voltage surges on AC power circuits with system voltages Us above 1 kV up to and including 52 kV. This document basically applies to all metal-oxide distribution class surge arresters with internal series and\/or parallel gaps and housed in either porcelain or polymeric housings. This second edition cancels and replaces the first edition published in 2002. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:a) A new concept of arrester classification and energy withstand testing was introduced: the line discharge classification was replaced by a classification based on repetitive charge transfer rating (Qrs) and thermal charge transfer rating (Qth). The new concept clearly differentiates between impulse and thermal energy handling capability, which is reflected in the requirements as well as in the related test procedures. b) Power-frequency voltage versus time tests \u2013 with and without prior duty \u2013 were introduced as type tests. c) Requirements and tests on disconnectors were added. d) Definitions for new terms have been added. e) Clause 10 contains particular requirements for polymer-housed surge arresters. These are indicated in the form of replacements, additions or amendments to the original clauses or subclauses concerned. Keywords: testing of metal-oxide surge arresters<\/p>\n
