Good as new

This work describes the process involved in evaluating whether or not to reuse the generator's original compound excitation system and, if replaced, the type of excitation system that should be installed: compound or potential bus-fed type. It was determined that installing a used steam turbine generator at the plant would be a viable way to reduce manufacturing costs. This work discusses the issues encountered during the evaluation process, the expectations desired, the decisions made, and the outcome achieved as a result of the final decision to replace the existing compound excitation system with a potential bus-fed excitation system.
