Generator Load Bank Testing in Gauteng

Load bank testing runs a generator against a controlled artificial load to confirm it can deliver its rated power. It also burns off carbon buildup (wet stacking) common in generators that run lightly or rarely. Gentec Co tests on site across Gauteng.

Hospitals and clinics, data rooms, factories, retail centres, offices, farms and any site where the generator is critical or lightly used.

  • Confirms the generator carries full load before you need it
  • Clears carbon buildup from the engine and exhaust
  • Exposes cooling, fuel and voltage problems under stress
  • Gives you test records for insurance and compliance

We also perform megger testing, which measures insulation resistance in generator windings. It detects moisture and insulation breakdown before they cause a failure. It's especially useful for older units and generators stored in damp conditions.

How Testing Works

  1. We connect the load bank to your generator on site.
  2. We apply load in stages while monitoring temperature, voltage, frequency and fuel use.
  3. We report any issues found.
  4. We recommend next steps if repairs are needed.
