6-5 Final Steps to Be Taken Before
Energizing Equipment
The following steps should be taken before energizing the
equipment:
1. Manually exercise all switches, circuit breakers, and
other operating mechanisms to make certain they are
properly aligned and operate freely.
2.
Conduct an electrical insulation resistance test to make
sure the switchgear is free from short circuits and
grounds. This should be done both phase-to-ground and
phase-to-phase with the switches or circuit breakers
both opened and closed. This test should be performed
with a 1000-volt megger. Disconnect all control circuits
before checking resistance.
3. Check for secure mounting and wiring connections at
Entellisys instrumentation.
4. Using the Entellisys HMI, exercise all EntelliGuard
breakers to determine all devices work correctly. See
DEH-231 for instructions on using the Entellisys HMI.
.
5.
Test all protection functions using the Entellisys
System Test Kit. See DEH-233 for instructions.
6.
Make certain that field wiring is clear of live bus and,
where necessary, physically secured to withstand the
effects of fault currents.
7. Check to determine that all grounding connections are
made properly.
8. Remove all debris, scrap wire, etc., from the switchgear
interior before closing the enclosure.
9. Install covers, close doors, and make certain that no
wires are pinched and that all enclosure parts are
properly aligned and tightened.
