Foreword

This foreword is not part of NEMA TP 80050-202x (formerly NEMA TR 1-2013) Transformers, Step

Voltage Regulators, and Reactors.

The Standards appearing in this publication have been developed by the Transformer Section and have

been approved for publication by the National Electrical Manufacturers Association. They are used by the

electrical industry to promote production economies and to assist users in the proper selection of

transformers.

The Transformer Section is working actively with the IEEE Committee, C57 on Transformers, Regulators,

and Reactors, in the development, correlation, and maintenance of national Standards for transformers.

This Committee operates under the procedures both the American National Standards Institute (ANSI)

and the Institute of Electrical and Electronics Engineers (IEEE).

It is the policy of the NEMA Transformer Section to remove material from the NEMA Standards

publication as it is adopted and published in the IEEE C57 series Standards. The NEMA Standards

publication for Transformers, Regulators, and Reactors references these and other American

National Standards applying to transformers and is intended to supplement without duplication both

the American National and IEEE Standards.

The NEMA Standards publication for transformers, regulators, and reactors contains a provision for the

following:

a. IEEE and American National Standards adopted by reference and applicable exceptions

approved by NEMA if any.

b. NEMA Official Standards Proposals—These are official drafts of proposed Standards

developed within NEMA or in cooperation with other interested organizations, for

consideration by ANSI and IEEE. They have a maximum life of ten years, during which

time they must be revised as American National Standards, IEEE Standards, or adopted

as NEMA Standards, or rescinded.

c. Manufacturing Standards—These are NEMA Standards which are primarily of interest to

the manufacturers of transformers and which are not yet included in an American

National or IEEE Standards.

d. Standards Which Are Controversial—These are NEMA Standards, on which there is a

difference of opinion within Committee C57. The NEMA version will be included in the

NEMA Standards publication until such time as the differences between ANSI, IEEE, and

NEMA are resolved.

NEMA Standards publications are subject to periodic review and take into consideration user input. They

are being revised constantly to meet changing economic conditions and technical progress. Users should

secure the latest editions. Proposed or recommended revisions should be submitted to:
