Resistive Load Bank Testing for Generator
At GCM we provide resistive load bank testing to test your generator under controlled electrical conditions, checking its output, stability, and overall performance.
We carry out our resistive load testing service for generators across manufacturing, healthcare, construction, education, commercial buildings and industrial facilities.
Where required, we also perform reactive and combined load bank testing based on your generator and site requirements. We provide fast load bank testing across the UK, with engineers available to support your testing requirements.
When the power fails, we won't!
Generator Resistive Load Testing
We monitor the generator throughout the resistive load bank test to check its performance under load and identify any issues affecting operation. Applying a controlled load allows us to assess the generator beyond its normal operating conditions and confirm that it can deliver the required electrical output when needed. This is particularly important for standby generators that may rarely operate at their rated capacity, as issues can remain unnoticed until the generator is called upon during a power failure.
Key points included in our resistive load testing:
- Generator output
- Voltage and frequency
- Engine performance
- Oil pressure and temperature
- Cooling system and airflow
- Engine and radiator performance
- Fuel delivery
- Exhaust and carbon build-up
- Applied load performance
- Faults and abnormal readings
After testing, we assess the results and identify any faults or performance issues that require attention. Where repairs or maintenance are needed, we recommend the appropriate next step.
Controlled Load Testing
Resistive load testing uses a controlled electrical load rather than relying on the site’s normal electrical demand, allowing our engineers to assess how your generator performs under load.
The load is typically increased progressively through 25%, 50%, 75% and up to 100% of the generator’s rated output, where appropriate. At each stage, we monitor key parameters including voltage, frequency, temperature, and engine performance.
The exact load profile and test duration depend on the generator’s capacity, system configuration, manufacturer requirements, and purpose of the test. Contact GCM to arrange resistive load bank testing for your generator across the UK.
