Nov 05, 2019 11:22

29 ноября 2019 г. завершается обсуждение документа 1/2407/CDV (CDV - проект комитета с голосованием), который представляет собой проект нового стандарта МЭК 60050-195 «Международный электротехнический словарь. Часть 195. Заземление и защита от поражения электрическим током». Его подготовили на основе результатов обсуждения документа 1/2358/CD (см. https://y-kharechko.livejournal.com/69152.html , https://y-kharechko.livejournal.com/69591.html ). При этом были учтены некоторые наши замечания и предложения по уточнению и дополнению терминологии стандарта МЭК 60050-195. В документе 1/2407/CDV приведены следующие термины и их определения, которые соответствуют нашим предложениям:
195-01-08
earth, verb
ground, verb US

Note 1 to entry: The connection to local earth can be
- intentional, or
- unintentional or accidental
and can be permanent or temporary.
195-02-01
earth electrode
ground electrode, US
conductive part that is in electric contact with local earth, directly or through an intermediate conductive medium
195-02-15

resonant grounded system, US
system in which at least one live part is earthed through a device having an inductance designed to compensate approximately for the line-to-earth capacitances in the case of a single line-to-earth fault
EXAMPLE The following are examples of a "resonant earthed system": arc-suppression-coil earthed system, peterson coil earthed system and earth fault compensation system
195-04-12
line-to-earth short-circuit
short-circuit between a line conductor (IEV 195-02-08) and the Earth, in a solidly earthed system (IEV 195-04-06) or in an impedance earthed system (IEV 195-04-08)
195-06-01
basic protection
protection against electric shock under normal conditions

Однако большая часть предложений по уточнению и дополнению терминологии стандарта МЭК 60050-195 не была учтена при подготовке документа 1/2407/CDV. Таким образом, на обсуждение была представлена устаревшая терминология, которая не соответствует современной национальной терминологии, подготовленной нами для ГОСТ 30331.1 (см. http:// y-kharechko.livejournal.com/4077.html , http:// y-kharechko.livejournal.com/7044.html ), ГОСТ IEC 61140 (см. http://y-kharechko.livejournal.com/1016.html ), ГОСТ 29322 (см. http:// y-kharechko.livejournal.com/5633.html ), ГОСТ 32966 (см. http:// y-kharechko.livejournal.com/3041.html ), ГОСТ 33542 (см. http:// y-kharechko.livejournal.com/18503.html ).
Поэтому необходимо уточнить терминологию стандарта МЭК 60050-195 следующим образом (обоснования см. https://y-kharechko.livejournal.com/58345.html , https://y-kharechko.livejournal.com/58471.html , https://y-kharechko.livejournal.com/59066.html , New - новый пункт, который следует включить в стандарт).
