IEC 61439-5:2023 is available as IEC 61439-5:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the 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.

Sestavi nizkonapetostnih stikalnih in krmilnih naprav - 5. del: Sestavi za distribucijo električne energije v javnih omrežjih (IEC 61439-5:2023)
Ta dokument določa posebne zahteve za sestave za distribucijo električne energije v javnih omrežjih (PENDA).
Sestavi za distribucijo električne energije v javnih omrežjih vključujejo naslednja merila:
– uporabljajo se za distribucijo električne energije v trifaznih sistemih, katerih nazivna napetost ne presega 1000 V AC (za tipično distribucijsko omrežje glej sliko 101) oziroma 1500 V DC;
– so stacionarni;
– ta dokument ne zajema sestavov odprtega tipa;
– primerni so za namestitev v prostorih, do katerih ima dostop le usposobljeno osebje, vendar se lahko namestijo tudi zunanje enote, kadar so te dostopne laikom, za:
• uporabo pri distribuciji energije v javnih električnih omrežjih;
• notranjo uporabo: sestavi za vgradnjo znotraj elektroenergetskih postaj;
• zunanjo uporabo: sestavi, ki vsebujejo ohišje, primerno za namestitev na prostem.
Namen tega dokumenta je navesti definicije in določiti pogoje uporabe, konstrukcijske zahteve, tehnične značilnosti in preskuse za sestave za distribucijo električne energije v javnih omrežjih. Preskusi na višji ravni učinkovitosti delovanja so lahko uporabni z nekaterimi omrežnimi parametri.
Sestavi za distribucijo električne energije v javnih omrežjih lahko vsebujejo tudi krmilne in/ali signalne naprave, povezane z distribucijo električne energije.
OPOMBA 1: Naprave za nadzor in spremljanje se lahko uporabljajo v aplikacijah pametnega omrežja ali pri prenosu podatkov pametnega omrežja.
Ta dokument se uporablja za vse sestave ne glede na to, ali so oblikovani, proizvedeni enkratno ali v celoti standardizirani in proizvedeni v velikih količinah.
Proizvodnjo in/ali sestavljanje lahko izvaja oseba, ki ni prvotni proizvajalec (glej 3.10.1 standarda IEC 61439-1:2020).
Ta dokument se ne uporablja za posamezne naprave in samostojne dele, kot so zaganjalniki, varovalna stikala, elektronska oprema itd., ki so skladni z ustreznimi standardi za izdelek.
Če je postaja v lasti ali upravljanju operaterja javnega distribucijskega sistema (DSO), sestavi, ki se uporabljajo kot razdelilne plošče LV v transformatorskih postajah, spadajo na področje uporabe tega dokumenta.
Ta dokument se ne uporablja za posebne vrste sestavov, ki so zajeti v drugih delih skupine standardov IEC 61439.
OPOMBA 2: Če je sestav opremljen z dodatno opremo (na primer števci) na tak način, da se glavna funkcija znatno spremeni, se morda uporabljajo tudi drugi standardi, kot se dogovorita uporabnik in proizvajalec (glej 8.5 standarda IEC 61439-1:2020).
OPOMBA 3: Kjer to dovoljujejo lokalni predpisi in prakse, se lahko sestav v skladu s tem dokumentom uporablja v drugih omrežjih in ne samo javnih.
OPOMBA 4: Operaterji javnega distribucijskega sistema lahko določijo dodatne zahteve za svoje sestave.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts
