Comments on standards Comments for revision of IEEE Standards documents are welcome from any interested party, regardless of membership affiliation with IEEE. However, IEEE does not

Letters of Assurance may indicate whether the Submitter is willing or unwilling to grant licenses under patent rights without compensation or under reasonable rates, with reasonable terms and conditions that are demonstrably

Transformers, directly connected to generators, experience excitation and short-circuit duties beyond those covered in other pow
49、er transformer standards. Therefore, in 1979, the IEEE Transformers Committee decided that an application guide for such transformers was needed. In 1989, the IEEE Std C57.116 was approved and describes the selection, application, and specification considerations for the unit and unit auxiliaries transformers taking into account their connections, voltage and kilovolt ampere ratings; and excitation and through-fault capabilities during possible operating conditions, both normal and abnormal. Also included are load-tap changing and isolated phase-bus duct heating consideration
