Bibliography

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.
