Anotácia textu normy IEC 61439-5-ed.3.0-RLV :
IEC 61439-5:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61439-5:2023 defines the specific requirements for public electricity network distribution assemblies (PENDAs). PENDAs have the following criteria: - used for the distribution of electrical energy in three phase systems for which the rated voltage does not exceed 1 000 V AC (see Figure 101 for a typical distribution network) and DC systems not exceeding 1 500 V DC; - stationary; - open type assemblies are not covered by this document; - suitable for installation in places where only skilled persons have access for their use, however, outdoor types can be installed in situations that are accessible to ordinary persons - intended for use in energy distribution in public power grids; - indoor use: assemblies for installation inside of electric power substations; - outdoor use: assemblies containing an enclosure suitable for open air installation. This third edition cancels and replaces the second edition published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) omission of the requirement to conduct mechanical tests at -25 °C when enclosures are made of a metallic material; b) addition of assumed loading factors generation supplies and electric vehicle charging applications; c) additional dielectric tests when a PENDA is used in a distribution substation with separate HV and LV earths; d) further clarification of representative samples for design verification. The content of the corrigendum 1 (2025-02) has been included in this copy.
