Course overview

Generators play a crucial role in the Bulk Electric System. They are the source customers rely on for electrical power to assist in daily life. Ensuring a generator lasts means periodic overhauls in which the generator's internal components are inspected and repaired or replaced as necessary. Technicians must have a general understanding of common issues and fault diagnosis. They must also be able to determine if the generator can continue to operate.

The Generator Overhaul training course discusses the steps taken to shut down the generator and prepare it for maintenance. It also describes considerations when performing the overhaul inspections. This online course focuses on:

  • Generator shutdown
  • End shields inspection
  • Stator inspection
  • Hydrogen cooler inspection
  • Rotor inspection
  • Electrical testing
  • Reassembly

The Generator Overhauled course is part of the Industrial Motors training series.
