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.
Generator load bank test report.
The generator is then step loaded with the load bank until the desired load level is reached.
The testing for an annual load bank test and the triennial exercise may be combined according to nfpa 110 2010.
At 25 of the nameplate kilowatt rating for 30 minutes.
After the test the technician removes the load bank load first and transfers all switches back to the normal position before allowing the generator to cool down according to manufacturer guidelines.
At 50 of the nameplate kilowatt rating for 30 minutes.
The only way to determine whether the generator will cope under a full load is to test your generator at its full kilowatt kw output rating.
Each step to last fifteen 15 minutes record engine and generator data as detailed later in this section.
And every 36 months you ll need to run level 1 epss systems for the amount of time specified in your application s class up to four hours of runtime 8 4 9 1 2.
The key to a proper load bank test is that it tests your generator at its full kilowatt kw output rating.
In more detail the process occurs in this manner.
It is also important that the load bank is situated in free air space for adequate cooling.
Load bank testing for two continuous hours each year.
Any examples are for illustrative purposes only.
Ideally the load bank should be connected to the load side of the generator breaker.
The emergency switchgear should be disabled to avoid accidental transfer to facility load.
6 4 4 1 1 2 specifies that the 10 second criterion does not apply during the monthly testing of the generator.
It verifies that all primary components of the generator set are in proper working condition.
A load bank test ensures that your generator will run property when it s needed so that you can fully depend on it during an emergency situation.
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.
During this two hour period the unit should be operated as follows.
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.
Can the generator load bank test be combined to meet the 36 month test as well as the 4 hour load test.
If a generator fails the monthly test it should be operated under a load supplied by a load bank i e.
