Fundamentals of Generators & Alternators

SECOND EDITION CONTENTS
This treatise was written for those who are involved in operating, maintaining and trouble-shooting electrical generators, specifically Gensets, and who want to acquire a better understanding of the principles governing the machines' design and operation, but who do not have an electrical engineering background. The précis starts by introducing the rudiments of electricity and magnetism, quickly building up to a description of the basic laws of physics governing the operation of the synchronous electric machine. The second part of the book discusses, in detail, the methodologies of maintenance techniques and protection mechanisms related to these sysmtems.
