Handbook of Large Turbo Generator Operation and Maintenance

Handbook of Large Turbo Generator Operation and Maintenance by Geoff Klempner and Isidor Kerszenbaum. This book is designed to partially fill the gap by offering a comprehensive view of the many issues related to the operation, inspection, maintenance, and troubleshooting of large turbine generators. The contents of this third edition have been significantly enhanced and many new additional topics included. All of the information in the book is the result of many years of combined hands-on experience of the authors. It was written with the machine operator and inspector in mind, as well as providing a guide to uprating and life enhancement of large generators. This book, however, is about the practical aspects that characterize the design, operation, and maintenance of large turbine-driven generators.
