8、rms and definitions relating to power electronics. The terms and definitions are technically identical with the corresponding terms appearing in Chapter551, first edition, of the International Electrotechnical Vocabulary. This standard revises and supersedes BS4727-2:Group02:1971 which is now withdr

9、awn. BS4727 combines into one glossary the subjects previously covered by BS204 “Glossary of terms used in telecommunication (including radio) and electronics”, BS205 “Glossary of terms used in electrical engineering”, BS233 “Glossary of terms used in illumination and photometry” and BS1611 “Glossar

10、y of colour terms used in science and in industry”. These four glossaries have now been withdrawn. The glossary is divided into four main Parts, each of which is further subdivided into Groups. Each Group will comprise the terms and definitions used in a particular branch of electrical engineering a

11、nd will be issued individually as soon as it is completed. This arrangement makes it possible to add new Groups or revise existing Groups at any time without affecting the remainder of the glossary. The four main Parts of the glossary are as follows. Part 1: Terms common to power, telecommunications

12、 and electronics; Part 2: Terms particular to power engineering; Part 3: Terms particular to telecommunications and electronics; Part 4: Terms particular to lighting and colour. Fundamental and general terms common to power, telecommunications and electronics respectively form the first two Groups o

13、f Part1. General terms particular to Part2 and Part3 similarly form the first Groups of their respective Parts. The specialist Groups contain only the terms and definitions relating to their subject. As far as has been practicable all terms and definitions established in current usage and falling wi

14、thin the scope of this glossary have been included. Experience has shown that it is rarely possible to replace, or even to modify, a well established term no matter what the logical or aesthetic shortcomings of that term may be. Current usage has therefore been accepted as the authority for terms an

15、d their meanings except where there has been a very good reason for doing otherwise, e.g.where terms have been considered to be fundamentally wrong, ambiguous, superfluous or in need of standardization. Where two or more synonymous terms are in use, those which are deprecated are omitted from the bo

16、dy of the text but are entered in the alphabetical index with a cross-reference to the standard term. In cases where it was felt that the time was not yet right to deprecate a synonym, preferred terms are given first and other terms are printed in less prominent type to indicate the intention to dep

17、recate them in the course of time. Where synonyms are considered of equal value they are shown in the same type. Where terms are used with somewhat different meanings in different branches of electrical engineering, appropriate definitions are given in the Groups of the glossary corresponding to the

18、se branches. Such a definition, when taken out of the context of its Group, should always be quoted with a preamble indicating its proper context. It is to be noted that the given definition of a term represents the generally accepted meaning of that term. Under no circumstances should it be regarde

19、d as taking the place of a specification.BS4727-2:Group02:1983 BSI 08-1999 iii An effort has been made to arrange the terms in a logical order proceeding from the general to the specific and from the whole to the part and placing allied terms in proximity. Each term has assigned to it a Part number

20、(one digit) and a Group number of two digits followed by a space and four digits, the first digit of which represents the section, the second digit the subsection and the last two digits the place within the subsection. The International Electrotechnical Vocabulary employs a different numbering syst

21、em and for convenience the IEV number is given in parentheses after the BS number for each term. A general view of the arrangement of the Group in the glossary can be obtained from the guide to the glossary. An alphabetical index of the terms of the Group is provided at the end to facilitate referen

22、ce to particular terms. For simplicity, only the last four digits of a terms number are quoted in the index. It is recommended that the user of any Group of the glossary should consider the Group in association with the Groups covering general or fundamental terms within the Part, for Parts2 and3, a

23、nd also together with Groups01 and02 of Part1. In this glossary parentheses ( ) enclose words or phrases that are not part of the term or definition and can be omitted without affecting the meaning. A British Standard does not purport to include all the necessary provisions of a contract. Users of B

24、ritish Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
