No discharge should occur on the surfaces of equipment at
the operating voltage. This can, for example, be detected by
characteristic noises, a clearly perceptible smell of ozone, or
visible glowing in the dark.
NOTE
Should partial discharges occur as a result of
condensation, application of a thin silicone film
over the surface concerned is often effective as a
temporary remedy. It is advisable to ask the ABB
after-sales service department for advice regarding
permanent solutions to this uncommon type of
problem.
REPAIR MEASURES
If any irregular conditions are detected, appropriate servicing
or repair measures must be taken.
20.4 SERVICING
INSTRUCTIONS
If the need for servicing measures is established during the
course of an inspection, proceed as follows:
1. Clean all parts (e.g motors and mechanisms) with a
vacuum cleaner and visually inspect them. Clean the
surfaces in general:
− Lightly settled dry dust deposits: clean with a soft dry
cloth.
2. Perform a closing/opening operation on all disconnectors
and circuit-breakers, fuse switches, and earthing switches.
3. Connect the auxiliary control voltage, but ensure that no
remote signals can activate the components. Perform one
electrical operation sequence on all motor-operated de-
vices and tripping mechanisms.
4. For maintenance of gas-pressure, follow gas-chapter for
further instructions.
5. Completely remove all rust from damaged paint work areas
on steel sheet and other steel parts by mechanical means,
e.g. with a wire brush, and apply appropriate anti-corrosion
treatment.
20.5 REPAIRS
NOTE
If the switchgear is damaged, contact ABB to eva-
luate necessary repairs. Some advanced repairs/
operations should be carried out only by ABB
service personnel.
Carry out repair work immediately after a defect has been
discovered.
CAUTION
Follow the maintenance instructions in the manuals
for the relative components.
