IEC TR 60664-2-2:2002(E) Provides an overview of the different kinds of surge overvoltages that can occur on low-voltage installations and equipment. In particular:
– the magnitude and duration of typical surges as well as their frequency of occurrence;
– information on overvoltages resulting from interaction between power and communication systems;
– guidelines when considering interface issues in relation to insulation coordination;
– guidelines concerning surge protection means on the basis of availability and risk considerations, including interaction within the system;
– highlights temporary overvoltages and other factors that have to be taken into account for insulation coordination, primarily related to protective control using surge protective devices.
