Load Bank Testing

Load Bank Testing
Load Bank Testing Services

Overview

Load bank testing is the only reliable way to confirm a diesel generator will perform under the conditions it’s expected to handle.

AC Automation provides resistive and resistive-reactive load bank testing up to 3 MW, using our own in-house load bank fleet.

Every test is delivered by experienced engineers who interpret what the data actually means — not just record it.

Benefits

Verified Performance

Confirm your generator will deliver full rated output when it matters most — proven, not assumed.

Prevent Wet Stacking

Regular load bank testing prevents fuel and oil residue build-up, protecting long-term engine reliability.

ISO 8528 Compliance

Step load tests carried out to ISO 8528 standards, including G2 performance class verification.

Multi-Scale Testing

In-house load banks support testing from small standby sets through to 3 MW installations.

Engineering Insight

Tests delivered by experienced engineers who interpret what the data means — not just record it.

Comprehensive Reporting

Test reports include logged parameters, graphs, pass/fail criteria, and clear recommendations where issues arise.

Features

  • Resistive and resistive-reactive load banks up to 3 MW capacity in-house
  • Step load testing to ISO 8528, including G2 performance class verification
  • Transient response, voltage and frequency stability, and full-load endurance runs
  • Parameter logging — engine temperatures, fuel consumption, exhaust temperatures, and electrical outputs
  • FAT, witness testing, and PPM contract testing all supported

Get in Touch

Need to confirm your generator will perform under full load, prevent wet stacking on a critical standby asset, or carry out witness or FAT testing on a new installation? Our engineers can attend site or factory with our own load banks — up to 3 MW capacity.

Why Choose Us

Many providers can connect a load bank and run a generator at full output. AC Automation goes further — combining the testing itself with the engineering experience to understand what the data actually means. Anomalies in transient response, exhaust temperatures, or load acceptance often point to underlying issues that need attention, and our engineers know what to look for.

With load banks up to 3 MW in our own fleet, testing can be carried out at any scale — standalone, as part of a PPM contract, or alongside commissioning, fuel polishing, or remedial works for a complete view of generator health.
