Low-voltage switchgear and controlgear assemblies - Part 5: Assemblies for power distribution in public networks (IEC 61439-5:2023)

This document 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.
The object of this document is to state the definitions and to specify the service conditions,
construction requirements, technical characteristics and tests for PENDAs. Tests at higher
performance level can be applicable with some network parameters.
PENDAs can also include control and or signalling devices associated with the distribution of
electrical energy.
NOTE 1 Control and monitoring devices can be used in smart grid applications or the transmission of smart grid
data.
This document applies to all PENDAs whether they are designed, manufactured on a one-off
basis or fully standardised and manufactured in quantity.
The manufacture and/or assembly can be carried out other than by the original manufacturer
(see 3.10.1 of IEC 61439-1:2020).
This document does not apply to individual devices and self-contained components, such as
motor starters, fuse switches, electronic equipment, etc. which comply with the relevant product
standards.
If the substation is owned or operated by a public distribution system operator (DSO), PENDA’s
which are used as LV distribution panels in transformer substations are within the scope of this
document,
This document does not apply to specific types of assemblies covered by other parts of
IEC 61439 series.
NOTE 2 If a PENDA is equipped with additional equipment (for example meters), in such a way that the main
function is changed considerably, then other standards can also apply as agreed between user and manufacturer
(see 8.5 of IEC 61439-1:2020).
NOTE 3 Where local regulations and practices permit, a PENDA according to this document can be used in other
than public networks.
NOTE 4 DSO’s can define additional requirements for their PENDA’s.

Ensembles d'appareillage à basse tension - Partie 5: Ensembles pour réseaux de distribution publique (IEC 61439-5:2023)

IEC 61439-5:2023 est disponible sous forme de IEC 61439-5:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.

L'IEC 61439-5:2023 définit les exigences spécifiques aux ensembles pour réseaux de distribution publique d'électricité (ERD). Les ERD remplissent les critères suivants:
- ils sont utilisés pour la distribution de l'énergie électrique dans des systèmes triphasés pour lesquels la tension assignée ne dépasse pas 1 000 V en courant alternatif (se reporter à la Figure 101 qui représente un réseau de distribution classique) et des systèmes à courant continu qui ne dépassent pas 1 500 V en courant continu;
- ils sont fixes;
- les ensembles ouverts ne sont pas couverts par le présent document;
- ils sont adaptés à une installation dans des emplacements où seules des personnes qualifiées ont accès pour leur utilisation; cependant, les types pour l'extérieur peuvent être installés dans des endroits accessibles à des personnes ordinaires;
- ils sont destinés à être utilisés dans les réseaux de distribution publique;
- à l'intérieur: ensembles installés à l'intérieur de postes d'alimentation électrique;
- à l'extérieur: ensembles avec une enveloppe adaptée à une installation en plein air.
Cette troisième édition annule et remplace la deuxième édition parue en 2014. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) omission de l'exigence de réalisation d'essais mécaniques à -25 °C lorsque les enveloppes sont en matériau métallique;
b) ajout d'application de charge de véhicules électriques et de production d'énergie avec des facteurs de charge présumés;
c) ajout d'essais diélectriques lorsqu'un ERD est utilisé dans un poste avec terres HT et BT séparées;
d) description plus détaillée des échantillons représentatifs pour la vérification de la conception.

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.
