scope:

This Guide covers general recommendations for the operation, loading, and maintenance of turbinedriven synchronous generators of the types specified in Section 4. below, having cylindrical rotors and conventional cooling systems (in distinction from conductor- cooled systems). It does not apply to generators having salient-pole rotors.

This Guide is not intended to supplant specific or general instructions contained in the manufacturer's instruction book or in any contractual agreement between a manufacturer and a purchaser of a given machine.

Because of the rapid development in generator design and because of individual ingenuity of generator designers, many variations are incorporated in existing machines. It is not, therefore, possible in this Guide to assign specific values or fixed methods in its various sections. The most that this Guide can accomplish is to provide guideposts which, on one hand, disclose accepted and tried values or methods and, on the other hand, give warning where hazards might be encountered. The user should keep in mind that this Guide is written in terms of the turbine-generator, and that certain considerations herein have been included because of their importance in directing attention to other related matters. This Guide is not intended to apply in any manner to the prime mover.
