The International Electrotechnical Commission (IEC) is the world's leading organization for the preparation and publication of international standards for electrical, electronic, and related technologies. Founded in 1906, the IEC provides a global platform for companies, industries, and governments to meet, discuss, and develop the international standards they require.
A Technical Committee (TC) in IEC is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
IEC 61439-5:2010 gives specific requirements for public electricity network distribution assemblies (PENDAs), which are stationary assemblies verified by verification tests, as defined in this standard. These ASSEMBLIES are used for the distribution of electrical energy in three-phase systems (see Figure 101 for a typical distribution network). Open type ASSEMBLIES are not covered by this standard. This first edition of IEC 61439-5 cancels and replaces the second edition of IEC 60439-5 (2006), and constitutes a technical revision. This edition of IEC 61439-5 includes the following significant technical changes with respect to the latest edition of IEC 60439-5:
- alignment on IEC 61439-1 regarding the structure and technical content, as applicable;
- introduction of new verifications, accordingly;
- harmonisation of the requirements of substation cable distribution boards and cable distribution cabinets, thereby eliminating the need to identify and define two catagories of assembly;
- simpler standard as a result of a reduction in the number of assembly types defined and the acronyms used to identify the different assemblies.
This publication is to be read in conjunction with IEC 61439-1:2009.
