A-deviations
A-deviation: National deviation due to regulations, the alteration of which is for the time being outside
the competence of the CEN/CENELEC member.
This European Standard does not fall under any Directive of the EC.
In the relevant CENELEC countries these A-deviations are valid instead of the provisions of the
European Standard until they have been removed.
Clause Deviation
5.5 Austria (Elektroschutzverordnung 1995 BGBl. 706/1995)
Work on active parts may only be started if the voltage has been disconnected according
to the five safety rules laid down in ÖVE E 5 Part 1:1989 and ÖVE EN 50110, Part
1:1997-06. Therefore, voltage indicating elements shall bear the information:
"Nicht zum Feststellen der Spannungsfreiheit zulässig"
(English translation: "Not allowed for detection of absence of voltage".
Germany (Accident Prevention Regulation BGV A2 "Elektrische Anlagen und
Betriebsmittel" based on the German Labour Protection law (7. August 1996, BGBl.
IS.1246))
According to paragraph 2 of § 6 of the BGV A2, work on active parts may only be started
if the voltage has been disconnected according to the five safety rules. At medium
voltage switchgear and controlgear the detection of the voltage disconnection (the 3rd
safety rule) may be carried out with voltage detectors or voltage detecting systems only.
To prevent accidents the user/operator shall be in a position to differentiate
unambiguously between the voltage detecting systems and the voltage indicating
systems. Voltage indicating systems shall therefore bear the following additional marking:
"Nicht zum Feststellen der Spannungsfreiheit zulässig!"
(English translation: "Not allowed for detection!")

HIGH-VOLTAGE PREFABRICATED SWITCHGEAR

VOLTAGE PRESENCE INDICATING SYSTEMS
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, the IEC publishes International Standards. Their preparation is
entrusted to technical committees; any IEC National Committee interested 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. The IEC collaborates closely with the International Organization
for Standardization (ISO) in accordance with conditions determined by agreement between the two
organizations.
2) The formal decisions or agreements of the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61958 has been prepared by subcommittee 17C: High-voltage enclosed
switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear.
The text of this standard is based on the following documents:
FDIS Report on voting
17C/253/FDIS 17C/258/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
The committee has decided that the contents of this publication will remain unchanged
until 2003. At this date, the publication will be
reconfirmed;
withdrawn;
replaced by a revised edition, or
amended.

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 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 detectors 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 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 indicated 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.

2 Service conditions
VPIS are designed to be used under the 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 voltage
NOTE 1 VPIS may also be used in conjunction with phase comparators.
NOTE 2 VPIS 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 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 gives 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 VPIS
3.6
nominal voltage (U )
n
suitable approximate value of voltage used to identify a system or device
[IEV 601-01-21, modified]
NOTE 1 The nominal voltage of the VPIS is the parameter associated with its clear indication. VPIS may have
one nominal voltage U , or a nominal voltage range. Limit values of the nominal voltage range are named U and
n nmin
U .
nmax
NOTE 2 In 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 the voltage at the output terminal of the coupling element in the
case of insulation failure

protection defined for the switchgear.
If the VPIS includes hazardous parts when in service, it shall provide at least an IPXXB degree
of protection according to IEC 60529, even when replaceable parts are removed.
