2.3 Storage
Switchgear
If it is necessary to store the switchgear equipment
for any length of time, the following precautions
should be taken to prevent corrosion or
deterioration.
1. Remove protective covering. Check thoroughly
for damage.
2. Store in a clean, dry, rodent-free location
with moderate temperature and provide
protective coverings to prevent dirt, water,
or other foreign substances from entering
the switchgear.
Caution: Remove all cartons, containers and any
other miscellaneous packaging and packing
material from inside the switchgear sections
before energizing any internal heaters. To prevent
fire, remove any plastic or polyethylene shrouding
from the switchgear sections before energizing any
internal heaters.
Prudence: Retirez tous les cartons, boîtes et
autres matériaux d'emballage de l'intérieur de
l'appareillage électrique avant d'allumer les
éléments thermiques internes. Pour éviter tout
risque d'incendie, retirez tout bâchage en plastique
ou polyéthylène de l'appareillage avant d'allumer
les éléments thermiques internes.
3. If dampness or condensation may be
encountered in the storage location, heaters
must be placed inside the switchgear sections to
prevent moisture damage. Approximately 250
watts of heat in each section is required. On
outdoor switchgear equipment, this may be
accomplished by making a temporary power
supply connection to the heaters already
installed in the equipment.
Caution: If the space heaters are to be
temporarily energized from external source,
it is important to remove the fuses on the
secondary side of the control power
transformer. This precaution is to prevent a
feedback of higher voltage to other portions
of the equipment through the CPT primary.
Prudence: Si les générateurs doivent être
temporairement allumés à partir d'une
source externe, il est important de retirer
les fusibles du côté secondaire du
transformateur d'alimentation. Ceci permet
d'éviter tout retour de tension plus élevée
vers d'autres parties de l'équipement via le
primaire du transformateur.
Circuit breakers
If circuit breakers are not to be placed into service
at once, remove them from their shipping cartons
and thoroughly inspect them for damage. If the
breakers are in satisfactory condition, replace the
breakers in their shipping cartons for storage. Do
not remove the circuit breaker shipping members
at this time.
Store the circuit breakers in a clean, dry location
in an upright position. They must be properly
supported to prevent bending of thestuds or
damage to any of the breaker parts. Do not remove
any protective grease until the circuit breakers are
ready to be installed. A plastic or canvas-type cover
should be provided to reduce the possibility of
damage to the breakers due to dust and water.
