4. Instructions for use
08 Example of KEVA
36 G22 sensor in appli-
cation
The voltage sensors are used:
• To convert large voltages in the primary circuit
of the network to the appropriate signal for the
secondary equipment (e.g. IEDs).
The use of a sensor for other purposes than those
described above is forbidden.
Routine test report
The routine test report includes following tests:
a) Verification of terminal marking.
b) Power-frequency withstand test on primary
voltage terminal.
c) Partial discharge measurement.
d) Test for accuracy.
Note:
secondary terminals (connector) of the voltage
sensor is allowed.
Correction factors are measured separately for
each sensor during routine testing and are
marked on the rating plate.
The use of correction factors is required condi-
tion in order to achieve the declared accuracy
class.

5. Instructions for maintenance
Excessive dust or other kinds of pollution shall be
brushed off the sensor. Polluted sensors can be
cleaned with spirit, petrol or toluene. Otherwise,
during normal use the sensors do not need any
additional maintenance.
6. Transport and storage
The permissible transport and storage tempera-
ture for sensors is -40...+80 °C. During transport
and storage the sensors shall be protected
against direct sunshine. The sensors are delivered
packed into wooden boxes or transport pallets.
The conical surface must be protected against
damage.
7. Recommended procedure for
disposal of the sensor
The sensor does not contain environmentally haz-
ardous materials. For disposal of the product af-
ter it has been taken out of use, local regulations,
if there are any, should be followed.
