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.

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

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.

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

Averaged over the microphone positions, the level of the background noise shall be at least
6 dB(A) but preferably more than 15 dB(A) below the sound pressure level to be measured. If
the difference between the sound pressure levels of the background noise and the source
noise is between 6 dB(A) and 15 dB(A), a correction shall be applied as described in 8.3 of
ISO 3744:1994.
The instrumentation system, including the microphone and cable, shall meet the requirements
for a class 1 instrument specified in IEC 61672-1. The filters used shall meet the requirements
for a class 1 instrument specified in IEC 61260.
During each series of measurements, a sound calibrator with an accuracy of class 1 specified
in IEC 60942 shall be applied to the microphone to verify the calibration of the entire
instrument system.
The audible perceptibility test shall be performed by energizing the voltage detector by any
relevant means corresponding to the application of the threshold voltage plus 10 %.
The voltage detector shall be arranged as shown in Figure 6a, in such a manner that the
sound axis of the voltage detector is parallel to the ground and at least 1,5 m away from any
sound-reflecting surfaces.
A measuring plane shall be established, perpendicular to the sound axis according to
Figure 6a. The distance of 400 mm can be increased by 200 mm if this will enable higher
sound intensities to be measured.
The measurements shall be carried out for the indications "voltage present" and "voltage not
present", at each of the twelve microphone positions of Figure 6b. The sound pressure level
shall be measured in each octave band of the frequency range 1 000 Hz to 4 000 Hz, with the
A-weighting network.

The period of observation shall be at least 10 s for a continuous signal. For an intermittent
signal, the integration time for the measurement shall be shorter than the signal duration.
The test shall be considered as passed, if for each microphone position, the sound pressure
level, within at least one octave band of the frequency range of interest, is greater than
– 80 dB(A), (ref.: 20 μPa) for a voltage detector with continuous sound signal;
– 77 dB(A), (ref.: 20 μPa) for a voltage detector with intermittent sound signal.
When there is an additional visual indication these values may be reduced by 10 dB(A).
NOTE 2 Other higher values may be agreed between manufacturer and customer for specific usage in very noisy
areas.
6.2.3.2 Alternative test for voltage detectors having completed the production phase
The alternative test consists in comparing the perceptibility of the audible indication of a
manufactured voltage detector to the one of a voltage detector which has passed successfully
the type test according to 6.2.3.1 (reference voltage detector). The test shall be considered as
passed if both perceptibilities are almost identical.

increased 2 °K/min until it reaches the high value according to the climatic category of the
voltage detector (see Table 1). The relative humidity shall be maintained at 50 %.
The chamber shall be kept at the high temperature for 3 h. During the first hour and half, the
relative humidity shall be increased from 50 % to 96 %.
The test piece shall then be removed from the climatic chamber and within 5 min to 10 min
following the withdrawal, the measurement of the threshold voltage shall be carried out
according to 6.2.1.2.1 at ambient temperature. Wiping of external parts is allowed.
The test shall be considered as passed if the two measured threshold voltages satisfy the
limits specified in 4.2.1.2.
NOTE This test procedure combines conditions of steady extreme temperatures and sudden change of
temperature, since it is not practical to perform high voltage tests in a climatic chamber.
6.4.6.2 Alternative means for voltage detectors having completed the production
phase
It is not practical to perform the test under climatic conditions after completing the production
phase for checking the conformity to the associated requirements. Nevertheless the
manufacturer shall prove that he has followed the same documented assembly procedure as
per the type tested device. The manufacturer shall document components that affect the
climatic performance.

G.2 Testing
Replace the existing text of the subclause by the following:
Table G.1 lists the tests that verify the physical integrity, the functioning of the voltage
detector and its insulation performance. It also recommends a chronological order for
performing the tests. The insulating stick to be used with voltage detectors as a separate
device should be covered by an IEC, regional, national or local/company standard.

For practical purposes, this test may be combined with the test for protection against bridging (number 4 of
the chronological list). The test duration for spark resistance is at least 5 s.
e
A comparison may be made with a reference voltage detector of the same design and using an alternative
high voltage test set-up.
Since the parameters of the test set-up and the test room arrangement can influence significantly the
measured value of the threshold voltage, it is recommended to measure and record the initial value of the
threshold voltage as obtained with this test set-up and this testing room, and to use the same configuration at
periodic intervals.
f
A comparison may be made with a reference voltage detector of the same design. Tests for clear
perceptibility may also be combined with other previous tests of the list.
NOTE According to the design of the voltage detector and its fabrication process, the manufacturer may specify
additional tests related to particular components or characteristics. These specific tests should be noted in the
instructions for use.
