This is a reference book for operators of large turbogenerators at power plants and power plant engineers. It shows how operators and engineers can diagnose a problem in a machine by examining its symptoms. The key motivation for the book is to provide power plant operators with easy-to-follow algorithms they can use to reduce forced-outage time, possibly saving millions of dollars in alternative production. The book also covers how to react to certain alarms and trips when returning units online.

Isidor Kerszenbaum, PhD, is an IEEE Fellow residing in Irvine, California. He is a generator specialist consulting to power plants on operation, maintenance and troubleshooting of large motors and generators. He is also active in the Electric Machinery Committee of the IEEE-PES.

Geoff Klempner, BASc, is an IEEE Fellow and generator specialist residing in Toronto, Canada. He has served in numerous IEEE committees and standards working groups for large generators. He is also a contributor to CIGRE on large rotating electrical machines.
