Koordinimi i izolimit për pajisje me sistem me tension të ulët - Pjesa 2-2: Konsideratat e ndërfaqes - Udhëzues zbatimi

Insulation coordination for equipment within low-voltage systems - Part 2-2: Interface considerations - Application guide

Scope

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.
