[Definition 2.5.1 of IEC 60743 and IEV 651-02-01]
NOTE For voltage detection, an insulating stick is intended to be attached to a voltage detector as a separate
device in order to provide the length to reach the installation to be tested and adequate safety distance and
insulation to the user.

4.2 Functional requirements
4.2.1 Clear indication
Replace the existing text by the following:
The voltage detector shall give an unambiguous indication of the presence and/or the
absence of the system operating voltage as a function of the nominal voltage or nominal
voltage range of the voltage detector, and its nominal frequency or nominal frequencies.
Indication may not be reliable in the vicinity of large conductive parts that create equipotential
zones.
When the voltage detector is used in accordance with instructions for use, the presence of an
adjacent live or earthed part shall not affect its indication.
When used in accordance with instructions for use, the voltage detector shall not indicate
"voltage present" for usual values of interference voltages.

– 4 – 61243-1 Amend.1 © IEC:2009
4.2.1.1 Continuous indication
The voltage detector shall give continuous indication when in direct contact with a live part.
4.2.1.2 Threshold voltage
4.2.1.2.1 General
The user shall not have access to the threshold voltage setting.
The indication “voltage present” shall appear if the voltage to earth on the part to be tested is
greater than 45 % of the nominal voltage.
NOTE 1 45 % of the nominal voltage corresponds to 0,78U 3 .
n
The indication "voltage present" shall not appear if the voltage to earth on the part to be
tested is equal to or less than 10 % of the nominal voltage.
NOTE 2 10 % of the nominal voltage corresponds to 0,17U 3 and is the maximum phase to earth induced
n
voltage normally encountered in the field.
To fulfil the above requirements, the threshold voltage U shall satisfy the following
t
relationship:
0,10 U max< U ≤ 0,45 U min
n t n
For voltage detectors with only one nominal voltage, U max. equals U min.

n n
NOTE 3 There is a theoretical limit of 4,5 to the ratio between U max. and U min. to achieve clear indication of

n n
the voltage detector. This value corresponds to the division of 0,45 by 0,1.
NOTE 4 It may happen that the induced voltage level on a specific network is higher than 10 % of the nominal
voltage or of the maximum nominal voltage of the range.
It may also happen that the variations of the nominal voltage network are such that the 0,45 U or 0,45 U max. is
n n
not the lowest possible value.
Moreover, when is it expected that the voltage detector will be used in the vicinity of large conductive parts that
create equipotential zones (see 4.2.1), the customer may specify a low value of the threshold voltage.
In all these cases, manufacturer and customer should reach an agreement to set the appropriate value for the
threshold voltage, while keeping it within the range specified above. The setting of the threshold voltage is further
limited by the requirements for clear indication which shorten the range of possible values, and the relevant tests
(clear indication) have to be passed.
4.2.1.2.2 Particular case of voltage detectors to be used on networks with low values
of interference voltage
In some cases, the customer may wish to take advantage of a network with low values of
interference voltage by reducing the lower limit of the threshold voltage below 0,10 U max.
n
NOTE 1 This particular case could help to deal with the use of the voltage detector in the vicinity of large
conductive parts. In spite of this change of the threshold voltage for a lower value, the theoretical limit of 4,5 for
the ratio between U max. and U min. still remains valid, and the relevant tests (clear indication) have to be

n n
passed.
In such case, the voltage detector shall have a special marking and a warning shall be
included in the instructions for use to inform the users of the modification brought to the
threshold voltage.
NOTE 2 The special marking should be the result of an agreement between the manufacturer and the client.

4.2.3 Temperature and humidity dependence of the indication
Replace the existing fourth paragraph by the following:
In these cases, the threshold voltage shall satisfy 4.2.1.2.

insulation performance of the voltage detector is concerned.
NOTE 2 The L values of Table 2 correspond to the minimum distance in air (obtained from Tables 1 and 2 of
i
IEC 61936-1) plus an additional safety distance.
NOTE 3 The L values of Table 2 can be used as a guidance to determine the length of the insulating stick used

with a voltage detector as a separate device. However, the length of the insulating stick for live working can be
shortened for voltage detectors as a separate device taking into account the minimum approach distances or in
accordance with national or regional regulations.

For L equal to or greater than 520 mm, conductive parts not exceeding 200 mm (in total),
i
measured from the limit mark towards the handle, are allowed within the minimum length of
the insulating element if they are completely externally insulated.

examination, tests, etc.) are specified within the test subclauses for the purpose of voltage
detectors having completed the production phase.
6.1.2 Type test
Replace the first item of the existing list by the following:
– The type tests shall be performed at the lowest and at the highest nominal voltages
delimiting the family of voltage detectors. Within the limits of the family, bridging tests
(6.3.1 and 6.3.2) shall be performed for each distance d of Table 8 under the highest
voltage of each voltage range. Mechanical tests shall be done only once covering the
worst conditions.
6.1.3 Routine test
Delete the subclause.
6.1.4 Sampling test
Delete the subclause.
6.1.5 Test methods
Renumber this subclause as 6.1.3.
6.2.1.2 Measurement of threshold voltage
Replace the existing text of the subclause by the following:
6.2.1.2.1 Type test
The test set-up used for the measurement of the threshold voltage is of the ball and ring type,
as shown in Figure 2.
The electrode arrangement is selected according to the category of the voltage detectors.
Figure 2a gives the arrangement for voltage detectors of category S and Figure 2b for voltage
detectors of category L.
For voltage detectors with a nominal voltage range, the test set-up shall be selected
according to the highest nominal voltage.

61243-1 Amend.1 © IEC:2009 – 7 –
The ball and ring electrodes shall be connected as shown in Figure 4a.
The voltage detector shall be installed in such a manner that its contact electrode touches the
ball electrode and the indicator is approximately concentrically located in relation to the ring
electrode (in the horizontal axis).
The threshold voltage shall be measured by increasing the test voltage until the status of the
signal changes according to its type of indication.
The test shall be considered as passed if the measured threshold voltage is within the limits
specified in 4.2.1.2.
6.2.1.2.2 Alternative test for voltage detectors having completed the production phase
The alternative test consists of checking that the threshold voltage of a manufactured voltage
detector is within ± 5 % of the threshold voltage of a voltage detector that has successfully
passed the type tests according to 6.2.1.2.1. This test can be performed by means of an
alternative high voltage test set up.
6.2.1.3 Influence of in-phase interference field
Replace the second sentence of the penultimate paragraph by the following:
For voltage detectors with a nominal voltage range, the tests shall be performed for the lower
nominal voltage.
6.2.1.5 Influence of interference voltage
Add the following new sentence at the end of the penultimate existing paragraph:
For low interference voltage detectors the test voltage shall be 95 % of the threshold voltage
specified in the agreement between the manufacturer and the customer.
6.2.2 Clear perceptibility of visual indication
Replace the existing text of the subclause by the following:
6.2.2.1 Type test
The test set-up is given in Figure 5.
The intensity of the light striking an unpolished grey screen with a reflectivity index of 18 %
and the signal source of the indicator shall be:
– 50 000 lux ± 10 % for outdoor type voltage detector with standard light D according to
CIE 15.2 corresponding to colour temperature of 5 500°K ± 10 %;
– 1 000 lux ± 10 % for indoor type voltage detector with standard light A according to
CIE 15.2 corresponding to colour temperature of 3 200°K ± 10 %.
The voltage detector is positioned in the direction of axis A – B, and its signal source part is
centered on the axis A – B in normal use, according to Figure 5a.
The visual perceptibility test shall be performed by energizing the voltage detector by any
relevant means corresponding to the application of the threshold voltage plus 10 %.

– 8 – 61243-1 Amend.1 © IEC:2009
By switching the voltage "on" and "off", the voltage detector is set to respond in such a
manner that the indications "voltage present" and "voltage not present" alternate several
times in conditions unknown to the observer.
Three observers with average sight look towards the voltage detector, through the 5 mm holes
in the front plate (see Figure 5b).
The test shall be considered as passed if the indication is seen by the three observers
through each hole.
6.2.2.2 Alternative test for voltage detectors having completed the production phase
The alternative test consists in comparing the perceptibility of the visual indication of a
manufactured voltage detector to the one of a voltage detector which has passed successfully
