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.
Generator load bank test report.
It is also important that the load bank is situated in free air space for adequate cooling.
If a generator fails the monthly test it should be operated under a load supplied by a load bank i e.
At 50 of the nameplate kilowatt rating for 30 minutes.
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.
Ideally the load bank should be connected to the load side of the generator breaker.
The testing for an annual load bank test and the triennial exercise may be combined according to nfpa 110 2010.
A generator load bank test involves an examination and assessment of a genset.
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.
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.
At 25 of the nameplate kilowatt rating for 30 minutes.
During a generator load bank test this device verifies that all primary components of your commercial standby generator are in proper working condition and it s ready to operate as required.
6 4 4 1 1 2 specifies that the 10 second criterion does not apply during the monthly testing of the generator.
Each step to last fifteen 15 minutes record engine and generator data as detailed later in this section.
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.
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.
During this two hour period the unit should be operated as follows.
Any examples are for illustrative purposes only.
Load bank testing for two continuous hours each year.
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.
Can the generator load bank test be combined to meet the 36 month test as well as the 4 hour load test.
It verifies that all primary components of the generator set are in proper working condition.
Generally speaking you ll need to perform a weekly inspection and a monthly load test on your epss 8 4 1.
