16、) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition
17、 to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
18、in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with con
19、ditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC Na
20、tional Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the
21、way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any I
22、EC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity.
23、 IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of
24、its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any o
25、ther IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be t
26、he subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a technical report when it has collected data o
27、f a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC 62711, which is a technical report, was prepared by IEC technical committee 3: Information structures, documentation and graphical symbols. The text of this technical report is
28、based on the following documents: Enquiry draft Report on voting 3/1029A/DTR 3/1041/RVC Full information on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directi
29、ves, Part 2. 4 TR 62711 IEC:2011(E) The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconf
30、irmed, withdrawn, replaced by a revised edition, or amended. A bilingual version of this standard may be issued at a later date. TR 62711 IEC:2011(E) 5 MNEMONICS AND DESIGNATIONS OF SYMBOLS FOR MEASURING RELAYS, INSTRUMENTS AND RELATED DEVICE 1 Scope This Technical Report provides recommendations fo
31、r consistent use of mnemonics and qualifying symbols to be applied to symbols representing devices used in systems for monitoring, protection, switching, and controlling of apparatus in electrical substations, generating stations, power utilization and conversion facilities, and equipment designed f
32、or automatic protection of power systems. The recommendations are intended for designers, manufacturers and engineers of such systems. For symbols of measuring relay and measuring instrument, it is intended to serve two purposes, namely: Give a review of standardized designations (as defined in this
33、 report); Limit the range of possible variants (after final standardization and introduction in IEC 60617). Symbols for measuring relays are symbols in which the functional behaviour of an element, mostly because of its complexity, is described by qualifying symbols e.g. IEC 60617-S00328 (2001-07),
34、IEC 60617-S00337 (2001-07), particularly by referring to supporting documentation; the relevant rules and explanations are to be found in IEC 60617 in the application notes associated with the symbols, e.g. IEC 60617-S00327 (2001-07) (A00091 through A00094).

The relevant rules and explanations are to be found in IEC 60617 in the
36、application notes associated with the symbols IEC 60617-S00910 (2001-07), IEC 60617-S00911 (2001-07) and IEC 60617-S00912 (A00144 through A00147).

For dated references, only the edition cited applies. For undated references, the latest edition o
38、f the referenced document (including any amendments) applies. IEC 60617, Graphical symbols for diagrams ISO/IEC 81714-1, Design of graphical symbols for use in the technical documentation of products Part 1: Basic rules 3 Terms and definitions For the purposes of this document, the following terms a
39、nd definitions apply. 3.1 protection relay measuring relay which, either solely or in combination with other relays, is a constituent of a protection equipment IEC 60050-448:1995, 448-11-02 4 Measuring relay symbols Power systems are extremely complicated electrical networks that are geographically
40、spread over very large areas. The power systems are so complex that a complete conventional diagram showing all the connections is impractical. There is some concise way of communicating the basic arrangement of power system components. This is done by using diagrams with universally accepted symbol
41、s in IEC 60617. When measuring relay symbols are required, pick the general symbol IEC 60617-S00327 (2001-07) (see Figure 1), and then combine it with one or more appropriate supplementary symbols. Some devices, especially newer devices, may not have universally accepted symbols. These devices could
42、 be represented in a number of ways, usually a matter of personal choice. In such instances, the symbol is usually accompanied by a verbal description. When an appropriate symbol does not exist, either the general symbol IEC 60617-S00327 (2001-07) should be applied, or a symbol may be constructed fo
43、llowing the rules of IEC 60617 and ISO/IEC 81714-1. 5 Measuring instruments When measuring instrument symbols are required, pick the general symbols from among IEC 60617-S00910 (2001-07), IEC 60617-S00911 (2001-07) and IEC 60617-S00912 (2001-07) according to the function, that is, indicating, record
44、ing and integrating (see Figure 1). Then the asterisk within the symbol is replaced with the letter symbol or the graphical symbol. The replacing symbol is related to the information displayed by the instrument regardless of the means used to obtain the information. TR 62711 IEC:2011(E) 7 6 Mnemonic
45、s and designations for measuring relays and instruments 6.1 Overview Where in Tables 1 to 19 below the letter “M” is shown in the second column, this means that the designation concerned may be used in measuring relay symbols. A letter “I” in the second column means that the designation concerned ma
46、y be in indicating instrument symbols. A letter “R” in the second column means that the designation concerned may be in recording instrument symbols. A letter “G” in the second column means that the designation concerned may be in integrating instrument symbols. In these tables, the English descript
47、ions appear in the fourth column, because in many cases designations are derived from terms in English. 6.2 Measuring relays Tables 1 to 18 present the mnemonics and designations for measuring relays.
