1. General
The integrated WEGA 2.2 voltage detecting system is a three-phase indication device which is
designed to display the operating voltage of medium-voltage switchgear installations. The device
complies with the requirements of the IEC 61243-5 standard (VDE 0682 Part 415) for capacitive
voltage detecting systems.
The WEGA 2.2 is built for the installation in switchgear units. It serves to detect and indicate the
operating condition of medium-voltage installations according to VDE 0105, Part 1 and Part 100.
Additional functions:
Relay signal when at least one of all three phases indicates ‚voltage present‘ (arrow).•

Universal voltage supply (auxiliary voltage): 24 to 230V AC or DC•
2. Regulations for use
The WEGA 2.2 is exclusively to be used to detect voltage conditions and phase comparisons. It is
imperative that the safety rules of VDE 0105, Part 1 and Part 100 are always observed when using
this voltage detecting device.
Please observe especially the following:
Integrated WEGA 2.2 voltage detecting systems are to be installed and used for the•
detection of the voltage condition only by electrically skilled or electrically instructed
persons.
Integrated WEGA 2.2 voltage detecting systems must only be used for the permissible•
nominal voltage (nominal voltage of the medium-voltage network) and nominal frequency.
The intended use and operation of the equipment must be in accordance with the operating
manual (section 5).
The unambiguous indication „voltage present“ according to IEC 61243-5 is ensured•
under the condition that the WEGA 2.2 voltage detecting system is used for its permissible
nominal voltage and nominal frequency and the adaptation is realized by matching
capacitors.
This indication appears in 3-phase systems in the range of 45% to 120% of the nominal•
voltage, however not in cases of less than 10% of the nominal voltage.
Integrated WEGA 2.2 voltage detecting systems are designed for indoor use only.•
Prior to accessing the medium-voltage area, verify all-pole isolation from the supply.•
In case of adverse lighting conditions or failure of auxiliary voltage supply it may be•
necessary to darken or additionally illuminate the visual display.
Integrated WEGA 2.2 voltage detecting systems are suitable for continuous operation.•

WEGA 2.2 4025122-001
Instructions for Use
Phase comparison can be carried out using phase comparators that comply with the•
requirements of LRM systems according to IEC 61243-5 (VDE 0682 Part 415) and
connecting them to the measuring and earth socket.
3. Design
Housing:
The integrated voltage detecting system WEGA 2.2 is located in a plug-in housing for panel mount
(for dimensions see drawing) suitable for a panel cut-out size of 92 x 45 mm. The LCD display, the
display test button and the three-phase LRM interface are located on the front panel. A removable
plug serves to protect the jacks against dust and corrosion. On the rear of the housing there are the
connections for the measuring signals, relays and auxiliary voltage.
Display:
The voltage conditions are indicated on the LC display. The individual symbols (arrow, dot and wrench)
appear in red colour. Pushing the button on the front panel, a display test can be carried out activating
all symbols on the display for a short time.
The indications of the arrow and dot symbols on the display do not require any auxiliary energy
because it is fed from the measuring signal. Even if the auxiliary voltage supply fails, the indication
functions will remain active. The additional functions (relay control, illumination of symbols and active
zero indication) require auxiliary voltage supply.

5. Operating Instructions
5.1 Function test
The function test can be carried out with the device in installed and thus active condition (indication
of arrow or arrow and dot) or in dismounted condition.
Testing with the device in active condition:
The test is carried out by short-circuiting one of the three measuring sockets with the earth socket.
The respective light of the arrow and dot symbol of L1, L2 or L3 will extinguish and the respective tool
symbol appear. The dedicated relay „No Voltage Present“ is switched on.
5.2 Testing with the device in non-active condition (Self-test)
This test can be carried out with the switchgear unit in voltage-free condition. The arrow and dot
symbols are not indicated. When the auxiliary voltage is switched on, the LCD display will be
illuminatedandthethreetoolsymbolsstartashing.Bygentlypushingthe„DisplayTest“buttonall
symbols of the LCD display will be illuminated for a short time.
5.3 Active zero voltage indication
This will be activated, once the switchgear unit switches to voltage-free condition. The indication is
visualizedbythreeashingtoolsymbolsatthebottomoftheLCDdisplayframe.Thisindicationis
permanently activated with the presence of auxiliary voltage.
If any of the dened indications fails to appear during function testing, this will be a sign
that the integrated voltage detecting system is defect. In this case its indication must not be
made use of for the evaluation of voltage conditions.

5.4 Voltage testing
The integrated WEGA 2.2 voltage detecting system is designed for continuous operation. Due to this
feature the WEGA 2.2 provides continuous voltage testing in the switchgear unit into which it has
been installed displaying the „Voltage Present“ condition by illuminated arrow and dot symbols.
According to VDE 105 Part 1 and Part 100 for xed-mounted devices, the user must verify the
voltage-free condition of the disconnected switchgear components by viewing the changes in the
display while the voltage is switched off.
Description of the visual indications in case of voltage testing: Refer to item 4. Technical data
Attention! If no voltage is detected on all three phases, check the integrated WEGA 2.2 voltage
testing system for proper function. If any of the dened indications fails to appear during
function testing, this will be a sign that the integrated voltage detecting system is defect. In
this case its indication must not be made use of for the evaluation of voltage conditions.
5.5 Phase comparison
The phase comparison is performed by means of a phase comparator for LRM systems according to
IEC61481(VDE0682Part415),e.g.theOrion3.0madebyHorstmannGmbH,whichisxedonto
the LRM interface on the front plate. The sockets are accessible after the protection caps have been
removed.
The attachment of the phase comparator to the device may result in a weaker illumination of the
corresponding arrow and dot symbols of the WEGA 2.2.
Rextheprotectioncapafterthephasecomparisonhasbeennished.
5.6 Relay signals
Therelay„VoltagePresent“or„U≠0“isswitchedonwhenthevoltageofatleastone•
phase is greater than 0.45 * Un.
The relay „No Voltage Present“ or „U = 0“ is switched on when the voltage of at least one•
phase is less than 0.10 * Un.
Each of the two relays has a change-over contact with a common connection
(C - Common), a normally closed contact (NC - normally closed) and a normally open contact
(NO - normally open). The relays contacts are electrically isolated from the measuring voltage and
auxiliary voltage. Depending on the value of the measuring signal the following relay functions will
be tripped:
