Generator Load Bank Testing Procedure

Load bank testing for two continuous hours each year.

Generator load bank testing procedure.

Our test procedures include load test generator set for a minimum of 1 or 2 or 4 consecutive hours. Step load the generator with the load bank until the desired load is reached. Check all fluids level in the generator. Start the generator and allow it to reach the normal temperature.

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. 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. These are some of the steps to test a load bank testing. 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. 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. As a minimum the following shall be observed and recorded at 25 50 80 and 100 stepped load during testing of diesel generators on site. Start and run the generator until the water temperature stabilizes.

During this two hour period the unit should be operated as follows. The last hour cannot be less than 75 of the emergency generator nameplate kw rating for a total of 4 continuous hours. Transfer all manual or automatic transfer switches to the emergency source. Run at 80 of rating with 100 verification or as described in service agreement.

6 4 4 1 1 2 specifies that the 10 second criterion does not apply during the monthly testing of the generator. The generator is then step loaded with the load bank until the desired load level is reached. 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. Transfer all manual or automatic transfer switches to the emergency source.

1 apply load in steps used for generator sizing design consultant specify. Load bank testing is a standard part of our preventative maintenance service agreements and is accomplished without any interruption to facility operations. At 25 of the nameplate kilowatt rating for 30 minutes. 1 volts and amps on each phase voltage unbalance between phases shall.

If a generator fails the monthly test it should be operated under a load supplied by a load bank i e. Perform a stepped load bank test. Duration of actual test varies based on type of test nfpa 110 and customer preference.
