Surge overvoltages and surge protection in low-voltage a.c. power systems. General basic information Ingestion-build-141043 publicly available statement is still1 Scope IEC 62066 is a technical report that presents a general overview on the different kinds of surge overvoltages that can occur on low voltage installations. Typical surge magnitude and duration as well as frequency of occurrence are described. Information on overvoltages resulting from interactions between power system and communications system is also provided. Additionally, general guidelines are given concerning surge protection means and
