6.2.3 Inspection of the moisture absorbing
agent
Check the operation of the moisture absorbing agent in the
unit with a colour indicator. This is located behind the
centre viewing window of the right-hand panel
(see Figure 6-1).
The indicator should be pale blue in colour.
Under normal operating conditions the moisture level inside
the Xiria unit is <15% due to the Silica Gel bag placed
inside before the enclosure is sealed.
When the moisture indicator turns to pink instead of blue
the moisture level inside the switchgear unit is more than
40%.
The type testing of the Xiria unit has been carried out with
the enclosure flaps open under normal atmospheric
humidity conditions of > 50-60%.
When a too high level of humidity is detected by a pink
coloured indicator (e.g. at annual inspection), then the unit
can still be safely switched but arrangements should be
made for the unit to be taken out of service.
A first visual inspection can be made to check for damages
to the outside of the enclosure, but where there is no
visible damage detected, Eaton can assist in a further
investigation into the loss of integrety of the enclosure and
possible rectification.
6.2.4 Testing voltage detection
Refer to Appendix 2 of this manual for inspection and
maintenance of the voltage detection system.
6.2.5 Inspecting the protection relay
Refer to the manual provided by the relay manufacturer for
inspection and maintenance of the protection relay.
6.2.6 Inspecting the overcurrent indicator
Refer to Appendix 4 of this manual for inspection and
maintenance of the overcurrent indicator system.
6.3 Decommissioning the unit
6.3.1 Material processing after dismantling
Eaton pays a great deal of attention to the environmentally-
friendly design aspects of its units and installations. Eaton
designs and manufactures in accordance with the ISO
14001 environmental standard. As far as we are currently
aware, Xiria designs do not include any raw materials or
other materials that pose a threat to the environment. It is
reasonable, therefore, not to expect any problems when
Xiria products are processed as waste products at the end
of their service life. The materials used in Xiria units are
suitable for re-use. At the end of the service life of a unit,
specialised companies will be able to dismantle a unit
which has been disposed of. All materials used are suitable
for recycling.
An 'Environmental declaration', stating which materials and
material quantities are used in Xiria installations, is
available upon request.
Check out local regulations prior to dismantling your old
installation.
