EN 60027-7:2010

Letter symbols to be used in electrical technology - Part 7: Power generation, transmission and distribution

IEC 60027-7:2010 is applicable to generation, transmission, and distribution of electric energy. It gives names and letter symbols for quantities and units. In addition, rules for multiple subscripts and their succession are given. It is an addition to IEC 60027-1. Therefore letter symbols already given in IEC 60027-1 are repeated only if they have a special meaning in the field of power generation, transmission, and distribution or if they are used in this field with special subscripts.

Formelzeichen für die Elektrotechnik - Teil 7: Energieerzeugung, -übertragung und -verteilung

Symboles littéraux à utiliser en électrotechnique - Partie 7: Production, transport et distribution de l’énergie électrique

La CEI 60027-7:2010 s'applique à la production, au transport et à la distribution de l'énergie électrique. Elle donne les noms et les symboles littéraux des grandeurs et unités. Elle fixe en outre des règles concernant les indices multiples et leur succession. Elle est une extension de la CEI 60027-1. Les symboles littéraux figurant déjà dans la CEI 60027-1 ne sont donc répétés que s'ils ont une signification particulière dans le domaine de la production, du transport et de la distribution de l'énergie électrique ou s'ils sont utilisés avec des indices particuliers dans ce domaine.

Črkovne oznake za elektrotehniko - 7. del: Proizvodnja, prenos in distribucija električne energije (IEC 60027-7:2010)

Ta del IEC 60027 velja za proizvodnjo, prenos in distribucijo električne energije. Podaja imena in črkovne oznake za količine in enote. Poleg tega podaja pravila v primeru več podpisanega besedila in njihovo zaporedje. Ta del IEC 60027 je dodatek k IEC 60027-1. Zato so črkovne oznake, ki so že podane v IEC 60027-1, ponovljene samo, če imajo poseben pomen na področju proizvodnje, prenosa in distribucije električne energije ali če se na tem področju uporabljajo s posebnim podpisanim besedilom. Navodila glede uporabe velikih in malih črk so podana v IEC 60027-1, 2.1, in navodila glede predstavitve kompleksnih količin so podana v IEC 60027-1, 1.6. Zato je v številnih primerih podan samo U namesto U, U = U ali u.
