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.

Special national conditions
Special national condition: National characteristic or practice that cannot be changed even over a long
period, e.g. climatic conditions, electrical earthing conditions.
NOTE If it affects harmonization, it forms part of the European Standard.
For the countries in which the relevant special national conditions apply these provisions are normative,
for other countries they are informative.
Clause Special national condition
7.4.4 United Kingdom
Replace the entire subclause by:
7.4.4 Short-circuit performance
7.4.4.1 Requirements
Short-time overcurrents shall not damage the output element. The output element shall still
operate under specified conditions, the surroundings of the tariff and load control equipment
shall not be endangered and protection against indirect contact shall be assured in all cases.
The test circuit shall be practically non-inductive.
7.4.4.2 Test of s.hort-circuit performance of the output element
The output element shall be able to carry a short-time overcurrent of 3 000 A rms with a
relative tolerance of + 0% to - 10 % for one half-cycle. The test circuit shall be practically non-
inductive. The open-circuit source voltage of the generator used for this test shall be Un
+ 5 % to - 5 %. This test shall be carried out with the switch closed and the contacts shall
remain closed after the test overcurrent has been applied. The test is passed if the protection
against indirect contact remains assured and if the output element can still be operated
correctly after the test overcurrent has been applied.
Where the output element is incorporated into an integrated meter the meter shall still meet
the requirements for influence of short-time overcurrents in the relevant standard for the
meter, including where the switch contact is in the current circuit. For polyphase meters and
switches the test shall be perfomed phase-by-phase.
NOTE The short-circuit test is not applicable to the low rating d.c. switch (30 V, 30 mA) and to load switches up to a
rated breaking current of 2 A.
