There are very limited measures in place to identify generator system weaknesses in the event of an unplanned power outage. As a result, many facilities are unaware of any problems with their backup power solutions. In many cases, diesel engines that run on very low loads – or no load at all – become unreliable. This can cost the business a lot of money. It can lead to smoky exhausts, carbon build-up, fuel system problems and lubricating oil deterioration. All of which impact generator efficiency and reliability. Load bank testing is used to help prevent unnecessary outlay to your business. It ensures that your generator works exactly as it should. 

So what is load bank testing? What are the benefits? And do you need specialist generator load banking equipment?   

 

What is load bank testing?

Generator load bank testing is when an artificial load brings the engine to an operating temperature that matches what it will be when in use. This ensures the generator is functioning sufficiently when it’s needed the most. 

Load bank testing is important as it checks that the generator engine is able to perform at the required horsepower needed in an emergency. As generators typically run at a lower level than the unit’s rated output capability, testing is an essential operation. By using an artificial load, the generator will reach full load operating temperature. This puts your mind at ease that it won’t let you down in an emergency situation.

As you can see, it is an essential part of generator maintenance and will help save your business money in the long run.

 

How does load bank testing work?

A load bank is required to perform a load bank test. At Woodlands, we have generator testing equipment that we can deliver straight to your facility. Our expert technician will attach the load bank to the generator then apply a full load. The generator will reach its rated operating temperature to ensure it’s functioning efficiently. 

The generator technician will start the generator off slowly, only applying 25% of its capacity. Then increase the load by 25% each hour. By the fourth hour, your generator will be running at 100% and our technician will be able to identify any running problems. 

 

What are the benefits of load bank testing?

Load bank testing is a great preventative measure to ensure you don’t encounter performance issues in the event of an emergency. But here are a few other benefits: 

  • Prevention is more cost effective than the cure
  • Reduced risk of mechanical failure due to extreme stress on engine system parameters.
  • Peace of mind your facility is protected from downtime
  • Helps to prevent wet stacking, which reduces engine life cycle and efficiency.
  • Cleans the generator by removing all the carbons from the engine.

Load bank testing benefits every business that relies on a generator. From hospitals, schools and banks to manufacturing plants, it’s recommended that a load bank test is performed at least once a year.
