Regulatory documents on the selection of surge arresters in different countries and the methods recommended by leading manufacturers of surge arresters are considered. The main parameters for the selection of surge arresters are considered. The main parameter of the surge arrester is considered in detail - the maximum long-term permissible operating voltage. Special attention is paid to the selection of surge arresters for switching and lightning overvoltage. The choice of an overvoltage arrester based on the explosion hazard condition and mechanical characteristics is also considered.ensurge arresterelectrical networksovervoltageswitching overvoltagelightning overvoltageArticle
