Superseded Standard

IEEE C57.12.91-1995

IEEE Standard Test Code for Dry-Type Distribution and Power Transformers

Superseded by C57.12.91-2001. Methods for performing tests specified in IEEE Std C57.12.01-1989 and other referenced standards applicable to dry-type distribution and power transformers are described. This standard is intended for use as a basis for performance, safety, and the proper testing of dry-type distribution and power transformers. This standard applies to all dry-type transformers except instrument transformers, step-voltage and induction voltage regulators, arc furnace transformers, rectifier transformers, specialty transformers, and mine transformers.
