Oprema za merjenje električne energije (izmenični tok) - Posebne zahteve - 21. del: Statični števci delovne energije (razreda 1 in 2) (IEC 62053-21:2003)

Ta del standarda IEC 62053 se uporablja le za novo proizvedene statične števce delovne energije razredov natančnosti 1 in 2 za merjenje delovne električne energije pri izmeničnem toku v omrežju 50 Hz ali 60 Hz ter se uporablja le za tipsko preskušanje teh števcev.
Uporablja se le za statične števce delovne energije za notranjo in zunanjo montažo, sestavljene iz merilnega elementa in zapisovalnika, priloženega v merilnem ohišju. Uporablja se tudi kot indikator obratovanja in preskusni izhod. Če ima števec merilni element za več vrst energije (multienergijski števci) ali če so drugi funkcionalni elementi, kot so indikatorji maksimuma, elektronski tarifni registri, časovna stikala, kontrolni prejemniki nihanj, podatkovni komunikacijski vmesniki itd., priloženi v merilno ohišje, se uporabljajo tudi ustrezni standardi za te elemente.
Ne uporablja se za:
– števce delovne energije, pri katerih napetost v povezovalnih priključkih presega 600 V (medlinijska napetost za števce večfaznih sistemov);
– prenosne števce;
– podatkovne vmesnike, povezane v register števca;
– referenčne števce.
Osnovna smernica glede preskusov sprejemljivosti je podana v standardu IEC 61358.
Vidik zanesljivosti je zajet v standardih iz skupine IEC 62059.

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
