|IEEE Program Manager|
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 601V or higher in the highest voltage winding. It is intended for use as a basis for performance, and 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 transformers f) Mine transformers g) Testing Transformers h) Welding Transformers
This revision addresses substantive changes to Clause 5, 10 and 11 This revision addresses substantive changes to Clause 5, Clause 10, and Clause 11 of IEEE Std C57.12.91-2001 to reflect current practice in the testing procedures of dry-type transformers. This revision does not address transformer requirements and specific test criteria; rather they are contained in appropriate standards such as IEEE Std C57.12.01 or in user specifications.
