Placing equipment into service
To place equipment in service for the first
time proceed as follows:
1. Check that the circuit breaker is OPEN
and all control circuits are energized.
2. Check torque of the bolts that secure the
roof bushings to the top plate of the
type SDV7 distribution circuit breaker.
Torque should be in the range of 20-25
ft-lbs (27-34 Nm).
3. Connect primary incoming power source
to circuit breaker.
4. Check all instruments, protective relays,
meters, etc.
5. Connect as small a load as possible and
observe instruments.
6. Gradually connect more load to the
equipment while observing instruments
until the full load is connected.
7. Check for signs of overheating of
primary and secondary circuits and
satisfactory operation of all instruments
during the first week of operation.
