Generator Maintenance Services, Level I

Generator Maintenance, Level I focuses on entry level theory, safety, and minor and major maintenance procedures. It includes electrical fundamentals, generator theory, basic introduction to NFPA 110 focusing on major and minor primary maintenance (PM) procedures, basic troubleshooting of the electrical starting system, trend analysis, and documentation (using PM check sheets and logs).


Learning Objectives: Upon completion of this course, students will...

  • Understand basic generator theory, principles of operation, and system functionality.
  • Perform minor and major maintenance procedures outlined in NFPA 110 to include voltage drop testing and coolant testing
  • Perform an observation inspection
  • Fill out check sheets accurately
  • Perform an oil, fuel, and air filter change
  • Read basic schematics
  • Perform basic troubleshooting and triage techniques

 

Generator Maintenance Services, Level II

Generator Maintenance Services, Level II builds on the foundation established in Level I, moving from introductory service tasks to more advanced troubleshooting and system theory. This hands-on program strengthens technical skills through procedures such as coolant system maintenance, block heater replacement, and relay testing. Students will also be introduced to load bank theory and operation while gaining a deeper understanding of critical systems including automatic voltage regulators (AVRs), governors, alternators, controls, and automatic transfer switches (ATS).

Learning Objectives: Upon completing this course, students will be able to:

  • Replace belts and hoses in the coolant system.
  • Perform a complete coolant flush.
  • Troubleshoot block heaters.
  • Explain replacement procedures for block heaters.
  • Test relays and basic control circuits to verify functionality.
  • Describe the purpose and procedures of load bank operation.
  • Explain the role of AVRs, governors, alternators, and the ATS in generator system performance.


The generator maintenance program is designed for service technicians and facility managers that are responsible for doing maintenance services in compliance with NFPA 110 requirements. This course may also be useful to you if you are new to industry and require a basic introduction into the technology, codes and standards, and recommended maintenance of emergency power supply systems.
