32、ATED SWITCHGEAR AND CONTROLGEAR ASSEMBLIES VOLTAGE PRESENCE INDICATING SYSTEMS 1 General 1.1 Scope This International Standard is applicable to voltage presence indicating systems (VPIS) incor- porated in a.c. switchgear and controlgear covered by IEC 60298 or IEC 60466. Voltage presence indicating
33、systems are devices used to provide information to operators about the voltage condition of the main circuit of the switchgear in which they are installed. The indication of VPIS alone is not sufficient to prove that the system is dead: if operating procedures make it mandatory, relevant voltage det
34、ectors according to IEC 61243 shall be used. This standard is also applicable to phase comparators specifically designed for use with VPIS. 1.2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International
35、 Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indica
36、ted below. For undated references, the latest edition of the normative document referred to applies. Members of IEC and ISO maintain registers of currently valid International Standards.

41、e same service conditions as the switchgear in which they are installed, as defined in clause 2 of IEC 60694. 3 Definitions For the purpose of this International Standard the following definitions apply. 3.1 voltage presence indicating system (VPIS) device used to indicate the presence of operating
42、voltage NOTE 1VPIS may also be used in conjunction with phase comparators. NOTE 2VPIS are not designed to detect reliably the absence of voltage: for this purpose, only voltage detectors or voltage detecting systems (VDS according to IEC 61243-5) should be used. 3.2 coupling element part of the VPIS
43、 connected to the main circuit which transmits to the indicating element a signal related to the voltage condition of this circuit. Different physical principles can be used for the coupling element, for example, capacitive, resistive, optical, etc. 3.3 indicating element part of the VPIS which give
44、s a visual indication depending on the input signal received from the coupling element 3.4 connecting point point of the indicating element where a suitable phase comparator may be connected 3.5 phase comparator apparatus which indicates the phase relationship between the connecting points of two VP
45、IS 3.6 nominal voltage (Un) suitable approximate value of voltage used to identify a system or device IEV 601-01-21, modified NOTE 1The nominal voltage of the VPIS is the parameter associated with its clear indication. VPIS may have one nominal voltage Un, or a nominal voltage range. Limit values of
46、 the nominal voltage range are named Unmin and Unmax. NOTE 2In this standard, the nominal voltage of a three-phase system is the normal phase-to-phase voltage. The nominal voltage of a single-phase system is the normal voltage between lines. 3.7 voltage limiting device protective device that limits
47、the voltage at the output terminal of the coupling element in the case of insulation failure Page 7 EN 61958:2001 BSI 8 April 2002 Licensed Copy: sheffieldun sheffieldun, na, Fri Nov 10 09:13:23 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 0002:CEI 85916 8 4 Ratings The following ratings of the switch
48、gear shall also be applicable to the VPIS incorporated in it: rated voltage; rated insulation level; rated frequency(ies). In addition, the nominal voltage, or nominal voltage range, of the systems on which the VPIS can be used, shall be defined. 4.1 Rated voltage Refer to 4.1 of IEC 60694. 4.2 Rate
49、d insulation level Refer to 4.2 of IEC 60694. 4.3 Rated frequency Refer to 4.3 of IEC 60694. 5 Design and construction 5.1 General 5.1.1 Parts of VPIS A VPIS includes a coupling element; an indicating element; a connecting point (optional). Both the coupling and indicating elements are fixed and incorporated in switchgear (see figure 1). 5.1.2 Phase comparison VPIS should allow checking of phase relationship by means of a suitable phase comparator.
