What Is Load-Bank Testing for Standby Generators?
Typically, a generator runs at a level far less than the unit’s rated output capability. Testing the load bank checks the engine’s ability to perform and provide the required horsepower when called upon in an emergency. This “exercise” verifies the generator’s overall reliability and ability to run at its full-rated kW output. The artificial load also brings the engine up to an acceptable operating temperature. Any generator set, whether the prime mover is diesel- or gaseous-fuel driven, can benefit from load-bank testing.
What Are the Benefits?
- Allows the engine to reach its full operating temperature
- “Burns out” the accumulation of unburnt fuel so the unit runs cleaner and more efficiently
- Offers the peace of mind that your standby generator is operating optimally
How Can You Ensure Reliability and Performance?
The performance and reliability of your standby power systems are critical during emergency situations or whenever your power goes out. IPSI Generator Services offer both in-house and on-site Load Bank Testing to verify your generator’s ability to perform at its maximum output under a full load.
Our Load Bank Services include:
- Connecting the generator/transfer switch and load bank
- Checking fluid levels and adding if necessary
- Running the generator at temperature and recording outputs
- Monitoring controls and adjusting RPM/voltage as needed
- Logging test results and providing a complete customer report
IPSI has the ability to load test diesel, natural gas and bi-fuel generators up to 600 Kilowatts.
How Often Should a Generator Be Load Tested?
In most cases, non-mission-critical generators should be tested at 80% of their maximum load for 60 minutes at least once a year. Critical diesel generators could be tested much more frequently, but this completely depends on individual requirements and industry regulations.
