scope:

This standard describes methods for performing tests specified in IEEE Std C.57.12.01 and other referenced standards applicable to dry-type distribution and power transformers, with a voltage of 601 V or higher in the highest voltage winding.2 It is intended for use as a basis for performance and for the proper testing of dry-type distribution and power transformers.

This standard applies to all dry-type transformers including those with solid cast and/or resin encapsulated windings, except as follows:

a) Instrument transformers

b) Step-voltage and induction voltage regulators

c) Arc furnace transformers

d) Rectifier transformers

e) Specialty and General Purpose transformers

f) Mine transformers

g) Testing transformers

h) Welding transformers

NOTE-Where IEEE standards do not exist for the transformers mentioned above or for other special transformers, this standard may be applicable as a whole or in parts subject to agreement between the parties responsible for the application and for the design of the transformer.3

Purpose

The purpose of this standard is to provide information regarding the procedures for the testing of dry-type transformers. Transformer requirements and specific test criteria are not a part of this standard but are contained in appropriate standards such as IEEE Std C57.12.01 or in user specifications.

2 Information on normative references can be found in Clause 2.

3 Notes in text, tables, and figures are given for information only and do not contain requirements needed to implement the standard.
