The following is the basic step by step procedure for performing load bank testing on a generator set by utilizing a portable resistive load bank unit.
Generator load bank test checklist.
Duration of actual test varies based on type of test nfpa 110 and customer preference.
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.
A generator load bank test involves an examination and assessment of a genset.
The load test on the generator shall be carried out increasing the load from 0 to 100 in steps of 25 using load bank.
At 25 of the nameplate kilowatt rating for 30 minutes.
6 4 4 1 1 2 specifies that the 10 second criterion does not apply during the monthly testing of the generator.
During this two hour period the unit should be operated as follows.
The key to a proper load bank test is that it tests your generator at its full kilowatt kw output rating.
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.
At 0 the run time shall be 5 mins for 25 10 mins for 50 10 mins for 75 3 hrs for 100 3 hrs.
It verifies that all primary components of the generator set are in proper working condition.
At 50 of the nameplate kilowatt rating for 30 minutes.
Generally speaking you ll need to perform a weekly inspection and a monthly load test on your epss 8 4 1.
Each step to last fifteen 15 minutes record engine and generator data as detailed later in this section.
The generator is then step loaded with the load bank until the desired load level is reached.
Standard load bank testing procedure.
In more detail the process occurs in this manner.
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.
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.
If a generator fails the monthly test it should be operated under a load supplied by a load bank i e.
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.
