Entellisys Low Voltage Switchgear
Chapter 8. Energizing the Switchgear
8-1 Before Energizing
Before switchgear is energized, a thorough final check should
be made using the following checklist: Refer to section 6-5 for
additional information.
• Breakers and other operating mechanisms exercised
• Electrical insulation resistance tested phase-to- phase
and phase-to-ground
• Entellisys instrumentation properly connected
• Electrically operated breakers and operating mechanisms
tested
• Ground fault protection system tested
• Protection settings properly set and tested.
• Field wiring secured and free of live bus
• Grounding connections made
• All debris, scrap wire, etc. removed
• All covers installed, doors closed and latched
8-2 Energizing Procedures
CAUTION: Energizing switchgear for the first time is
potentially dangerous. Therefore, qualified electrical
personnel should be present when the equipment is
energized. If problems caused by damage or poor
installation practices have not been detected in the
checkout procedure described previously, serious damage
can result when power is turned on.
ATTENTION: La mise sous tension pour la première fois
d’un dispositif de commutation est un acte potentiellement
dangereux. Il faut donc que du personnel qualifié en
électricité soit présent lorsque l’équipement est mis sous
tension. Si lors de la procédure de vérification décrite
précédemment des problèmes causés par des dommages ou
de mauvaises pratiques d’installation n’ont pas été
détectés, il peut en résulter des dommages sérieux lorsque
le contact est établi.
1.
There should be no load on the switchgear when it is
energized.
2.
Turn off all of the downstream loads, including those
such as motor control centers and other devices that
are remote from the switchgear.
3.
The equipment should be energized in sequence by
starting at the source end of the system and working
toward the load end. In other words, energize the main
devices, then the feeder devices, and then the branch-
circuit devices.
4. Turn the devices on using the Entellisys HMI.
