1. Operating conditions
The sensors should be mounted in dry, indoor conditions
without excess ingress of dust and corrosive gases. The sen-
sors shall be protected against unusually heavy deposits of
dust or similar pollution, as well as against direct sunshine.
The sensors are designed for standard ambient temperature
between -5°C and +40°C (storage and transportation tem-
perature between -40°C and +80°C). The altitude for mount-
ing should be lower than 1000 m above sea level. The sen-
sors may also be used at higher altitudes when agreed upon
with the manufacturer.
2. Technical details
For sensor dimensions see dimension drawings at the end
of these instructions. Interface of sensor (dimensions of
sensor cone) is done according to NKT & RAYCHEM blind
plugs. Rated values for each individual sensor are mentioned
on the rating plate glued to the sensor. Values mentioned on
the rating plate must not be exceeded.

Instructions for installation, use and
maintenance for the KEVA 36 G2x voltage
sensor
These instructions for installation, use and maintenance are valid for KEVA 36 G22
and KEVA 36 G23 type voltage electronic transformers (sensors) operating in indoor
conditions.
The voltage sensors type KEVA 36 G2x are intended to be used for voltage
measurement in gas insulated medium voltage switchgears. The voltage sensors are
designed as easy replacement of originally used insulating plugs/transformers in the
cross/end-adapters (e.g. NKT) or epoxy socket adapters. The housing of sensors is
made from aluminum which has to be grounded.

safety rules, especially when parts of the switch-
gear are in operation. Always ground the sensor
by the grounding terminal as it is shown on Fig. 4.
Installation conditions
The sensor should be installed in dry, indoor con-
ditions.
The temperature during the assembly shall be be-
tween 0 °C and +40°C. The sensor cable shall not
be moved or bent if the temperature is below 0°C.
Mechanical installation
The sensors can be mounted (screwed) into
adapters mentioned in the Tab. 1. During installa-
tion of the KEVA 36G2x sensor, the original insu-
lating plug will be removed from the busbar
adapter. Then the internal thread of the sensor
cone will be screwed to the bolt inside the
adapter (M12 or M16) and thus electrically con-
nects the sensor to the busbar.
Recommended mechanical installation:
0 step – Original installation, see picture 0.
1 step – Remove the plug cover, see picture 1.
2 step – Remove the insulating plug, see picture 2.
3 step – Clean the inside surface of the adapter
by paper towel, the inside cone must be

face (where is contact between the sen-
sor and the cable connector, see picture.

6 step – Assure that sensor cone is clean, coat
sensor cone with mounting grease NKT
MV3 (2152734 35).
Use a brush or a glove to spread the as-
sembly paste along the cone, see picture 6.
7 step – Place the sensor cone onto the adapter.
Press the sensor cone together with a
clean cable tie (to allow the air to escape)
into the adapter, see picture 7a and turn

Lightly tighten the sensor at the 30 mm
hexagonal nut, see picture 7b. Withdraw
the cable tie. Release the sensor by ap-
proximately 1 turn, see picture 7c. Screw
the sensor tight with a torque of 30 Nm,
see picture 7d.
8 step – Place the sensor base plate across the
sensor, see picture 8. Insert the four
screws M8 into the holes provided in the
sensor base plate and tighten them with
a torque of 30 Nm, assuring that one of
the screws is used to connect the sensor
grounding wire to the switchgear panel,
see picture 8.

Secondary cable, secondary connections
The secondary cable is a special shielded cable
designed to give maximum EMI shielding. The
secondary cable is inseparable part of each sen-
sor and cannot be additionally extended, short-
ened, branched, modified, withdrawn or changed
due to the guarantee of accuracy and perfor-
mance of the sensor.
The cable shall be connected directly (or via a
connector adapter if needed - for more informa-
tion about connector adapters and coupling
adapter refer to Doc. No. 1VLC000710 - Sensor Ac-
cessories) to Intelligent Electronic Device (e.g.
protection relay). The electrical shielding of cable
is connected to connector shielding and shall be
earthed on IED side.
The cable shall be fixed close to metal wall or in-
serted inside of metal cable tray far from power
cables! The minimal bending radius for the sec-
ondary cable is 35 mm. The cable cannot to be
moved if the temperature is below 0 °C. If cable,
connector or connector grommet is damaged
please contact the manufacturer for instructions.
Connection to the IED
The sensor cable is terminated by shielded RJ-45
plug connector that shall be connected to the in-
puts of the IED.
Note: It is recommended to use a cable tie to
fasten long sensor cables approximately 10 cm
from the RJ-45 socket.
The sensor plug connector pin’s assignment is
shown on Fig. 6. (Front view).

tee low resistance shielding; they are particularly
adapted to applications where electromagnetic
compatibility (EMC) is important. The connectors
are robust but it is necessary to be careful during
their assembly – do not use force!
Grounding terminal
The sensor grounding terminal is located at the
same side as the secondary cable connector. The
sensors has to be grounded during service by
grounding wire (length 0,5 m) with the cable eye
M8, as it is shown on Fig. 6. The sensor is deliv-
ered with attached grounding wire to the sensor
body.
