Electricity metering equipment (a.c.) - Particular requirements - Part 24: Static meters for reactive energy at fundamental frequency (classes 0,5 S, 1 S and 1)
IEC 62053-24:2014 applies only to newly manufactured transformer operated static var-hour meters of accuracy classes 0,5 S, and 1 S as well as direct connected static var-hour meters of accuracy class 1, for the measurement of alternating current electrical reactive energy in 50 Hz or 60 Hz networks and it applies to their type tests only. It uses a conventional definition of reactive energy where the reactive power and energy is calculated from the fundamental frequency components of the currents and voltages only.

Équipement de comptage de l’électricité (c.a.) - Exigences particulières - Partie 24: Compteurs statiques d’énergie réactive à la fréquence fondamentale (classes 0,5 S, 1 S et 1)
L'IEC 62053-24:2014 est applicable uniquement aux compteurs d'énergie réactive statiques neufs des classes de précision 0,5 S et 1 S alimentés par transformateurs ainsi qu'aux compteurs d'énergie réactive statiques neufs à branchement direct de classe de précision 1, destinés à la mesure de l'énergie électrique réactive en courant alternatif sur les réseaux électriques en 50 Hz et 60 Hz, et à leurs essais de type. Elle est fondée sur une définition conventionnelle de l'énergie réactive pour laquelle la puissance et l'énergie réactives ne sont calculées qu'à partir des composantes de fréquence fondamentale des courants et des tensions.
Oprema za merjenje električne energije (izmenični tok) - Posebne zahteve - 24. del: Statični števci osnovne komponente jalove energije (razredi 0,5 S, 1 S in 1) (IEC 62053-24:2014)
Ta del standarda IEC 62053 se uporablja le za novo proizvedene transformatorske statične števce jalove energije razredov natančnosti 0,5 S in 1 S ter neposredno povezane statične števce jalove energije razreda natančnosti 1 za merjenje jalove električne energije pri izmeničnem toku v omrežju 50 Hz ali 60 Hz ter se uporablja le za tipsko preskušanje teh števcev. V tem standardu se uporablja konvencionalna opredelitev jalove energije, kadar se jalova moč in energija izračunata le na podlagi komponent osnovnih frekvenc tokov in napetosti. Glej 3. točko.
OPOMBA 1: Ta pristop se razlikuje od pristopa iz standarda IEC 62053-23, kjer sta jalova moč in energija določeni le za sinusne signale. V tem standardu sta jalova moč in energija določeni za vse periodične signale. Jalova moč in energija sta določeni tako, da se doseže ustrezna ponovljivost meritev z različno zasnovanimi števci. Pri tej opredelitvi jalova moč in energija ne odražata skupnega nepotrebnega toka, ampak splošno nepotreben tok, ki ga je mogoče nadomestiti s kondenzatorji.
Uporablja se le za statične števce jalove 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 (multi energijski 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.
OPOMBA 2: V standardu IEC 61869-2:2012 so opisani transformatorji z merilnim obsegom 0,05 In do Imaks. za razrede natančnosti 0,2, 0,5, 1 in 2 ter transformatorji z merilnim obsegom 0,01 In do Imaks. za razreda natančnosti 0,2 S in 0,5 S. Ker se morata merilni obseg števca in z njim povezanih transformatorjev ujemati in ker imajo le transformatorji razreda 0,2 S/0,5 S značilnosti tokovnega pogreška in faznega pogreška, primerne za delovanje števca razreda 0,5 S/1 S, kot je opredeljeno v tem standardu, bo merilni obseg transformatorskih števcev 0,01 In do Imaks. Števci jalove energije, ki naj bi se uporabljali s transformatorji, ki niso razreda S, zato niso zajeti v tem standardu.
