3、oduction This introduction is not part of IEEE Std C57.12.51-2008, IEEE Standard for Ventilated Dry-Type Power Transformers, 501 kVA and Larger, Three-Phase, with High-Voltage 601 V to 34 500 V; Low-Voltage 208Y/120 V to 4160 VGeneral Requirements. This dry-type transformer standard describes ventil
4、ated dry-type transformers with self-cooled kilovolt- ampere ratings 501 V to 7500 V and high voltages 601 V to 34 500 V; forced-air-cooled ratings for certain sizes are listed in Clause 9. This standard is the result of an effort encompassing the interests of users, manufactures, and others dedicat
5、ed to developing voluntary consensus standards primarily for dry-type transformers. Table 2, Table 3, Table 9, Table 11, and Table 12 of this standard have been revised to coordinate with IEEE Std C57.12.01.a Table 4 has been revised to reflect industry practice. The copyright of this standard has b
6、een transferred from NEMA to IEEE. This standard is a voluntary consensus standard. Its use is mandatory only when required by a duly constituted legal authority or when specified in a contractual relationship. To meet specialized needs and to allow innovation, specific changes are permissible when
7、mutually determined by the user and the producer, provided such changes do not violate existing laws and are considered technically adequate for the function intended. Notice to users Laws and regulations Users of these documents should consult all applicable laws and regulations. Compliance with th
8、e provisions of this standard does not imply compliance to any applicable regulatory requirements. Implementers of the standard are responsible for observing or referring to the applicable regulatory requirements.
