Delta-Résistel’s load benches for gensets enable you to test, maintain and validate the performance of diesel or gas generators under real operating conditions.
Indispensable for maintainers, rental companies and installers, load testing guarantees the available power, electrical stability and reliability of the standby system.
Tests
Why test a generator set with a load bank?
A generator that has not been tested under real-life conditions can present major risks in the event of a power cut.
The load bank allows you to :
- Check power rating in kW / kVA
- Prevent engine fouling (wet stacking)
- Stabilize thermal operation
- Test voltage regulator and frequency
- Validate performance before commissioning
- Carry out preventive maintenance in accordance with manufacturer requirements
👉 A generator must operate at a sufficient load level to guarantee its longevity and performance.
