          Electrical, mechanical, and safety requirements are set forth for liquid-immersed distribution and power transformers, and autotransformers and regulating transformers; single and polyphase, with voltages of 601 V or higher in the highest voltage winding. This standard is a basis for the establishment of performance, limited electrical and mechanical interchangeability, and safety requirements of equipment described; and for assistance in the proper selection of such equipment. The requirements in this standard apply to all liquid-immersed distribution, power, and regulating transformers except the following: instrument transformers, step-voltage and induction voltage regulators, arc furnace transformers, rectifier transformers, specialty transformers, grounding transformers, mobile transformers, and mine transformers.<br />\n

This standard applies to all liquid-immersed distribution, power, and regulating transformers that do not belong to the following types of apparatus: a) Instrument transformers; b) Step voltage and induction voltage regulators; c) Arc furnace transformers; d) Rectifier transformers; e) Specialty transformers; f) Grounding transformers; g) Mobile transformers; h) Mine transformers<br />\n
          This standard is a basis for the establishment of performance and limited electrical and mechanical interchangeability requirements of the equipment are described. It is also a basis for assistance in the proper selection of such equipment.

          This standard was revised and greatly expanded in 1948, 1949, and 1956. The 1956 edition was comprised of a revision and editorial consolidation of the preceding standards on distribution, power , and regulating transformers, namely American Standard Requirements for Distribution, Power , and Regulating Transformers, and Reactors Other Than Current-Limiting Reactors, C57.12-1949, American Standard Test Code for Distribution , Power, and Regulating Transformers , C57.22-1948, and American Standard Requirements for Transformers-67,000 Volts and Below; 501 Through 10,000 kva, 3 Phase ; 501 Through 5,000 kva, 1 Phase, C57.12a-1954. In addition, in order to eliminate cross-references wherever possible, the consolidation contained excerpts from other standards of the C57 family<br />\n
          \t\t\t\t<br />\n
          This standard applies to all distribution and power transformers and to shunt reactors ex\u{AD}cept as indicated below:<br />\n
          Instrument Transformers (see USA Standard Requirements, Terminology, and Test Code for Instrument Transformers, C57.13-1968)<br />\n
          Constant-Current Transformers of the Moving\u{AD} Coil Type (see USA Standard Requirements, Terminology, and Test Code for Constant\u{AD} Current Transformers of the Moving-Coil Type, C57.14-1964)<br />\n
