Overview
FrançaisABSTRACT
This article deals with selection criteria and installation rules for low voltage surge protection devices (SPDs). It should be read in conjunction with Part 1, which deals with surge protection components and power systems. Secondary functions such as failure state indicators or remote information should be considered, but the main target must not be forgotten, namely protection. In this respect, selection rules for the various SPD parameters are given as a function of their impact on the level of protection obtained. SPDs for data networks are introduced, in particular when both types of network need to be protected for a single equipment item.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.
