During this two hour period the unit should be operated as follows.
Generator load bank test requirements.
The testing for an annual load bank test and the triennial exercise may be combined according to nfpa 110 2010.
Remove the load bank load first after the test.
For gasoline powered natural gas powered or propane powered generators that do not meet the testing requirements outlined in 1 a above it will likely be necessary to add more load to the generator or conduct a load bank test to comply with testing requirements a load bank is typically a mobile piece of equipment that simulates the actual.
2 in lieu of nfpa 110 5 13 2 3 h i hook up the dry type load bank to generator and perform a stepped load test on the generator at 25 50 80 and 100 of the nameplate kw rating of the generator.
Step load the generator with the load bank until the desired load is reached.
In addition to routine maintenance you ll also need to conduct ongoing operational tests of your epss.
Start and run the generator until the water temperature stabilizes.
It verifies that all primary components of the generator set are in proper working condition.
The equipment used to conduct a load bank test produces artificial loads on the generator by bringing the engine to an appropriate operating temperature and pressure level.
6 4 4 1 1 2 specifies that the 10 second criterion does not apply during the monthly testing of the generator.
This standard contains requirements covering the performance of emergency and standby power systems providing an alternate source of electrical power to loads in buildings and facilities in the event that the primary power source fails.
A generator load bank test involves an examination and assessment of a genset.
1 1 1 power systems covered in this standard include power sources transfer equipment controls supervisory equipment and all related electrical.
Can the generator load bank test be combined to meet the 36 month test as well as the 4 hour load test.
Load bank testing for two continuous hours each year.
At 25 of the nameplate kilowatt rating for 30 minutes.
The purpose of these tests are to periodically verify the function of the system against the standard.
Ongoing requirements according to nfpa 110 chapter 8.
O engine exhaust temperature during test if applicable p kw load under test q identification of unsatisfactory conditions and corrective action taken including parts replaced note.
Each step to last fifteen 15 minutes record engine and generator data as detailed later in this section.
Transfer all manual or automatic transfer switches to the emergency source.
The frequency schedule for load bank testing on a generator often depends on how the generator is classified and what it is a standby for.
8 2 4 3 if a generator fails the monthly test it should be operated under a load supplied by a load bank i e.
