Duration of actual test varies based on type of test nfpa 110 and customer preference.
Generator load bank test checklist.
The generator is then step loaded with the load bank until the desired load level is reached.
In more detail the process occurs in this manner.
It verifies that all primary components of the generator set are in proper working condition.
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.
Each step to last fifteen 15 minutes record engine and generator data as detailed later in this section.
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.
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.
Load bank testing for two continuous hours each year.
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 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.
The key to a proper load bank test is that it tests your generator at its full kilowatt kw output rating.
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.
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.
During this two hour period the unit should be operated as follows.
Standard load bank testing procedure.
6 4 4 1 1 2 specifies that the 10 second criterion does not apply during the monthly testing of the generator.
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.
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.
