Generator Load Bank Testing Procedure

Check all fluids level in the generator.

Generator load bank testing procedure.

Transfer all manual or automatic transfer switches to the emergency source. The recommended procedure to follow for the load bank test would be to. Duration of actual test varies based on type of test nfpa 110 and customer preference. 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. 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. At 50 of the nameplate kilowatt rating for 30 minutes. Step load the generator with the load bank until the desired load is reached.

Load bank testing for two continuous hours each year. 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 start and run the generator until the water temperature stabilizes. 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. Our test procedures include load test generator set for a minimum of 1 or 2 or 4 consecutive hours. 1 volts and amps on each phase voltage unbalance between phases shall. These are some of the steps to test a load bank testing.

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. During this two hour period the unit should be operated as follows. 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.

Step load the generator with the load bank until the desired load is reached. Start the generator and allow it to reach the normal temperature. Perform a stepped load bank test. 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.

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. Run at 80 of rating with 100 verification or as described in service agreement. 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.
