General Procedure For Generator Load Bank Rental Testing

In order to obtain accurate genset load bank rental test results, it is especially important to perform the correct test procedures . Otherwise, there will be a return false alarm state in mild cases, and the risk of damage to the generator in severe cases. At Rata Technology , the testers of the testers have at least hundreds of load bank rental test experience, and the testers ensure to provide you with accurate and complete generator test services.

After the tester has performed the correct load testing procedure , the load bank will verify that the generator is capable of delivering the required power . It also identifies potential problems that may exist with the generator and resolves them prior to the actual work. In order to properly implement the generator load test, I will briefly describe the steps that should be followed during the generator load rental test.

Step 1 – Fuel and Coolant Check

The first step for a generator load tester is to check the fluid level. The first thing to do is to confirm that the fuel tank is full and that the generator has an adequate supply of oil and coolant.

Step 2 – Startup and Operating Temperature Check

The test technician starts the generator and observes the operation of the generator . Wait for the generator to reach its standard operating temperature and listen carefully for any unusual noises. If there are any problems, testers need to stop the generator immediately until the problem is identified and corrected.

Step 3 - Connect the Load Bank

During this phase of the load bank test, the generator technician may need to apply the maximum load first and then add smaller loads until the generator is carrying a load that is half of the generator's maximum continuous rated load .

Step 4 - Amperage Check

Testers use an ammeter to check the voltage of the generator . The purpose of the amperage check is to verify that the generator 's voltage is neutral and does not drop below 105 volts at full load.

Step 5 – Load Bank Status Monitoring

Generator test technicians will continue to listen for unusual noises and monitor the generator for signs of overheating. For most generators, this phase can last 4-24 hours, but for industrial major generators, this phase can last a full week.

Step 6 - Disconnect the load and record the results

After the generator load bank rental test has reached the tester's desired specifications, the tester needs to gradually remove the load and let the generator run at a continuously reduced load for a period of time, usually for about an hour. With all loads removed, testers let the generator cool down before shutting down the unit completely . At this point, the tester records the results and advises the client on any needed corrections .
