Equipement de comptage de l'électricité - Prescriptions générales, essais et conditions d'essai - Partie 21: Equipement de tarification et contrôle de charge

L'IEC 62052-21:2004 spécifie les prescriptions générales pour les essais de type d'équipements neufs de tarification et contrôle de charge, de type intérieur, tels que des récepteurs de télécommande centralisée ou des horloges de tarification qui sont utilisés pour le contrôle de charges électriques, de registres multi-tarifs ou des dispositifs indicateurs de maximum. La présente version bilingue (2016-07) correspond à la version monolingue publiée en 2004-05.

Oprema za merjenje električne energije (a.c./izmenični tok) - Splošne zahteve, preskusi in pogoji preskušanja – 21. del: Oprema za krmiljenje tarif in bremen (IEC 62052- 21:2004)

Ta del standarda IEC 62052 določa splošne zahteve za tipsko preskušanje novo proizvedene notranje opreme za krmiljenje tarif in bremen, kot so elektronski zvočno frekvenčni omrežni sprejemniki in časovna stikala, ki se uporabljajo za krmiljenje električnih obremenitev, večtarifnih registrov ter indikatorjev maksimuma.
V tem standardu niso podane zahteve za konstrukcijske podrobnosti opreme za krmiljenje tarif in bremen.
Kadar je funkcija krmiljenja tarif in bremen vgrajena v večfunkcijsko opremo za merjenje električne energije, veljajo ustrezni deli tega standarda.
Ta standard ne obravnava preskusov sprejemljivosti in skladnosti. Kljub temu je primer preskusa sprejemljivosti podan v dodatku F.
Vidik zanesljivosti je zajet v dokumentih iz skupine standardov IEC 62059.
