PERFORMANCE TESTING

Load Bank Testing for Diesel Generators

A generator may start and run, but that does not always mean it is ready to perform under real site demand. Load bank testing applies a controlled electrical load to the generator, helping prove its output, identify potential issues and confirm that the system can support your site when required.

As part of planned maintenance or one-off testing, Yorkshire Diesel Power can carry out load bank support for commercial, industrial and critical sites across the UK. Our team combines testing with practical generator knowledge, helping spot performance problems, reduce the risk of failure and keep standby power systems ready for use.

Load bank Testing

Frequently Asked Questions

Useful answers about testing generator performance under controlled load, spotting hidden issues and proving standby power systems before they are needed.

A generator starting successfully does not always prove it can support the electrical demand of a real site. Load bank testing applies a controlled load, helping check whether the generator can produce stable power, run correctly under pressure and perform as expected beyond a basic start-up.

Load bank testing can be useful after installation, during planned maintenance, following repairs or before a generator is relied upon for a critical site. It is also valuable where a standby generator has not been used under proper load for some time, as light running can hide performance issues.

Testing may reveal issues such as unstable output, poor running, overheating, fuel problems, smoke, weak performance or faults that only appear when the generator is placed under demand. These problems may not be obvious during a simple start-up test, which is why controlled load testing can be valuable.

Yes. Standby generators often remain unused for long periods, so they may appear fine during a short test run but still struggle when placed under meaningful demand. Load bank testing helps confirm the generator is capable of supporting the site when it is genuinely needed.

It can help reduce risk by identifying weaknesses before they become urgent failures. Finding problems during planned testing gives the site time to arrange maintenance, repairs or further investigation, rather than discovering the issue during a power outage.

Yes. Load bank testing can be arranged alongside servicing, inspections, repairs and other generator maintenance work. This gives a more complete view of the generator’s condition, combining routine checks with performance testing under controlled load.
