M. Final Power Outage Test
- Notify responsible on site city
representative of your intentions to cut utility power on those circuits
protected by the stand-by generator system. Advise the city representative
that there will be at least a 10 second power outage on those circuits.
- After notification to the city, Use the test switches on the
generator switchgear panel to simulate a power outage. Observe the stand-by
generator set system to make sure if functions properly. Return the test
switch to the normal power position. Observe that the stand-by generator
shuts down properly. Make any adjustments necessary.
N. Site Wrap-Up
- Check to insure that all control switches are left in the proper position for automatic stand-by power protection.
- Complete all routine maintenance check lists and summary reports.
- Discuss the system condition with on-site personnel leaving with them copies of the maintenance check list. Insure a copy of the summary report is attached to the generator set.
O. Full Power Load Bank Test
A full power load bank test, using vendor supplied external test equipment and cables, will be conducted once per year.
- Connect the vendor supplied load bank to the system. Do not disconnect the generator set from the stand-by system to accomplish this hook-up.
- Exercise the generator set under load for no less than two hours. No less than one hour of this test should be at 100% of the generator set's name plate rating.
- Record the following areas of generator set performance:
- Load expressed as a percentage of maximum generator set rating
- Amps (all 3 legs if 3 phase)
- Oil Pressure
- Coolant Temperature
- Note both time and effect of any adjuestments attempted on the generator set during this test.
- At the conclusion of this test, disconnect the load bank and allow the generator set to run for ten minutes to cool down.
- Disconnect all external load test equipment and cables from the stand-by system leaving the system ready to respond automatically to a power outage.
- Leave the site in a state of good order and cleanliness.
- Write a load bank test report.
- Replace coolant with 50% 50% water and new (not recycled) antifreeze mixture.
