Information on the selection and application considerations for the unit power transformer and unit auxiliaries power transformer is provided in this guide. Consideration is given to connections that include direct connection and connections through generator circuit breakers and load-break switches. The considerations referred to in this guide apply to hydroelectric and thermal electric generating stations. Various power transformer connections and possible operating problems under normal and abnormal conditions are treated. Phasing procedures, basic impulse insulation level selection, and loading practices are not covered.

C57.116-1989
IEEE Guide for Transformers Directly Connected to Generators
The selection, application, and specification considerations for the unit transformer and unit auxiliaries transformers are described, taking into account their connections, voltage and kilovoltampere ratings, and excitation and through-fault capabilities during possible operating conditions, both normal and abnormal. Consideration is given to direct connections and connections through generator breakers and load-break switches. Both hydroelectric and thermal electric generating stations are covered. Phasing procedures, basic impulse insulation-level selection, and loading practices are not covered.
