Generator load bank testing procedure.
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.
Load bank testing for two continuous hours each year.
When combining both tests for diesel powered eps the first three hours of the test is required to be not less than 30 of the emergency generator nameplate kw rating or the minimum exhaust gas temperature.
Our test procedures include load test generator set for a minimum of 1 or 2 or 4 consecutive hours.
Perform a stepped load bank test.
Standard load bank testing procedure 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 recommended procedure to follow for the load bank test would be to start and run the generator until the water temperature stabilizes.
The generator is then step loaded with the load bank until the desired load level is reached.
The last hour cannot be less than 75 of the emergency generator nameplate kw rating for a total of 4 continuous hours.
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.
The recommended procedure to follow for the load bank test would be to.
Step load the generator with the load bank until the desired load is reached.
1 volts and amps on each phase voltage unbalance between phases shall.
Start and run the generator until the water temperature stabilizes.
These are some of the steps to test a load bank testing.
Start the generator and allow it to reach the normal temperature.
At 50 of the nameplate kilowatt rating for 30 minutes.
Run at 80 of rating with 100 verification or as described in service agreement.
Step load the generator with the load bank until the desired load is reached.
Duration of actual test varies based on type of test nfpa 110 and customer preference.
Transfer all manual or automatic transfer switches to the emergency source.
Check all fluids level in the generator.
Load bank testing is a standard part of our preventative maintenance service agreements and is accomplished without any interruption to facility operations.
If a generator fails the monthly test it should be operated under a load supplied by a load bank i e.
Make sure that the fuel tank is full the oil level is correct and the radiator or coolant tank is full if it is a water cooled generator.
Transfer all manual or automatic transfer switches to the emergency source.
