About This Course
This 2-day course covers the complete methodology of generator load bank testing. Participants learn the differences between resistive, reactive, and combined load testing, relevant standards (NFPA 110, ISO 8528), test planning, data collection and analysis, and professional reporting. The course includes hands-on testing sessions with actual resistive and reactive load banks at the HuaQuan Power testing facility.
Duration: 2 Days (16 Hours)

| Day 2 PM: Analysis & Reporting | Data analysis, pass/fail criteria, report writing, recommendations, compliance documentation | 4 | Workshop + Assessment |
Learning Objectives
- Explain the difference between resistive, reactive, and combined load testing and when each is appropriate.
- Plan and execute a complete generator load bank test in compliance with NFPA 110 and ISO 8528.
- Calculate load bank sizing requirements based on generator rating and test objectives.
- Collect and analyze load test data including voltage regulation, frequency regulation, and temperature measurements.
- Identify common generator problems revealed by load testing (wet stacking, cooling issues, AVR problems).
- Write professional load test reports with appropriate data, analysis, and recommendations.
Who Should Attend
Generator technicians, commissioning engineers, facility managers, and quality assurance personnel. Prerequisites: Generator Fundamentals course recommended. Basic electrical knowledge required.
Key Takeaways
- Load bank testing is the only way to verify that a generator can deliver its rated output under real conditions.
- NFPA 110 requires monthly exercise under load for Level 1 systems — load bank testing satisfies this requirement while also verifying capacity.
- Wet stacking prevention alone justifies the cost of annual load bank testing for lightly loaded standby generators.
- Reactive load testing (0.8 PF) stresses the excitation system in ways that resistive-only testing cannot.
