Electricity metering equipment (a.c.) - Part 2: Particular requirements - Electromechanical meters for active energy (class indexes A and B)

This European Standard applies to newly manufactured electromechanical watt-hour meters intended for residential, commercial and light industrial use, of class indexes A and B, for the measurement of alternating current electrical active energy in 50 Hz networks. It specifies particular requirements and type test methods. It applies to electromechanical watt-hour meters for indoor and outdoor application, consisting of a measuring element and register(s) enclosed together in a meter case. It also applies to operation indicator(s) and test output(s). If the meter has (a) measuring element(s) for more than one type of energy (multi-energy meters), or when other functional elements, like maximum demand indicators, electronic tariff registers, time switches, ripple control receivers, data communication interfaces etc. are enclosed in the meter case (multi-function meters) then this standard applies only for the active energy metering part. This standard distinguishes between: – meters of class indexes A and B; – direct connected and transformer operated meters; – meters for use in networks equipped with or without earth fault neutralizers. It does not apply to: – watt-hour meters where the voltage across the connection terminals exceeds 600 V (line-to-line voltage for meters for polyphase systems); – portable meters. Methods for acceptance testing are covered by the IEC 62058 series of standards 1). The dependability aspect is covered by the documents of the IEC 62059 series.

Equipement de comptage d'électricité (c.a.) - Partie 2: Prescriptions particulières - Compteurs électromécaniques d'énergie active (classes de précision A et B)

La présente Norme Européenne s'applique aux compteurs électromécaniques d'énergie active neufs, destinés à l'usage des habitations, des commerces et des petites industries, d'indices de classe A et B, et utilisés pour le mesurage de l'énergie électrique active en courant alternatif sur des réseaux à 50 Hz. Elle spécifie les exigences particulières et les méthodes d'essais de type. Elle n'est applicable qu'aux compteurs d'énergie active électromécaniques de types intérieur et extérieur, constitués d'un élément de mesure et d'un (des) élément(s) indicateur(s) rassemblés dans un même boîtier. Elle s'applique également à (aux) l'indicateur(s) de fonctionnement et au(x) dispositif(s) de sortie d'essai. Si le compteur a un (des) élément(s) de mesure pour plusieurs types d’énergie (compteurs d'énergies multiples), ou si d’autres éléments fonctionnels comme indicateurs de maximum, éléments indicateurs tarifaires électroniques, horloges de commutation, récepteurs de télécommande centralisée, interfaces de communication de données, etc. sont incorporés dans le boîtier du compteur (compteurs à fonctions multiples), la présente norme ne s'applique alors qu'à la partie de comptage de l'énergie active. La présente norme distingue entre : – les compteurs d'indices de classe A et B ; – les compteurs à branchement direct et ceux alimentés par transformateur ; – les compteurs utilisés dans des réseaux équipés ou non de neutraliseurs de défaut de terre. Elle n'est pas applicable aux : – compteurs d'énergie active dont la tension entre les bornes de raccordement excède 600 V (tension entre phases pour les compteurs des systèmes polyphasés) ; – compteurs portatifs. Les méthodes d'essais d'acceptation sont traitées par la série des normes CEI 620581). Les aspects de sûreté de fonctionnement sont traités par les documents de la série CEI 62059.

Oprema za merjenje električne energije (a.c.) - 2. del: Posebne zahteve - Elektromehanski števci za delovno energijo (razredna indeksa A in B)

Ta evropski standard se nanaša na novo proizvedene elektro mehanične merilnike Wh, namenjene za domačo, komercialno in industrijsko uporabo, razrednih indeksov A in B, za merjenje izmeničnega toka delovne energije v 50 Hz omrežju. Poudarja posebne zahteve in preskusne postopke. Nanaša se na elektro-mehanične merilnike Wh, za notranjo in zunanjo montažo, sestavljeno iz merilnega elementa in zapisovalnika priloženega v merilnem ohišju. Uporablja se tudi kot indikator obratovanja in preskusni izhod. Če ima merilnik več merilnih elementov za več vrst energije (multi energijski merilnik) ali ko so ostali funkcionalni elementi, kot indikatorji maksimuma, elektronski tarifni registri, časovna stikala, kontrolni prejemniki nihanj, podatkovni komunikacijsk interface, priloženi v merilno ohišje (multi funkcionalni merilniki) potem se ta standard nanaša samo na aktivni energijski merilni del. Ta standard razlikuje med: - merilniki z razrednimi indeksi A in B; - direktno povezanimi in prenosno delujočimi merilniki; merilniki za uporabo v omrežju opremljenemu z ali brez zemeljsko-stičnimi kompenzatorji.  Ne nanaša se na: -Wh merilnike, kjer napetost na priključnih sponkah presega 600 V (medlinijska napetost za merilnike za večfazne sisteme); - prenosne  merilnike. Postopki za prevzemne preskuse so zajeti v  IEC 62058 vrsti standardov. Zanesljivost pa je zajeta v dokumentih IEC 62059 vrste.
