Since IEEE standards represent a consensus of concerned interests, it is important that any responses to comments and ques

For this reason, IEEE and the members of its societies and Standards Coordinating Committees are not able to provide an instant response to comments or questions except in those cases where the matter has previously been addressed.

30、this standard, no position is taken by the IEEE with respect to the existence or validity of any patent rights in connection therewith. If a patent holder or patent applicant has filed a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE-SA Website a

The Accredited Standards Committee on Transformers, Regu

44、lators, and Reactors, C57, has for many years has been developing standards on transformers, regulators, and reactors. The data has been obtained from many sources, including the standards of the Institute of Electrical and Electronics Engineers, Inc. (IEEE) and the National Electrical Manufacturers

45、 Association (NEMA), as well as reports of committees of the Edison Electrical Institute, manufacturers, end users, and others. The revision of this standard includes additional mechanical and electrical requirements for accessories relating to pressure relief, loadbreak switch, and overcurrent prot

46、ection. The revision makes changes, including but not limited, to the following topics: Tank material Impedance voltage changes Kilovolt-ampere rating The revision also addresses various corrections and omissions not previously captured in the 2009 revision.
