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.

Note:
For use in alternative adapters please contact ABB.
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.
