Revision Standard - Superseded. Superseded by IEEE Std C57.12.90-2006 A common format for data files and exchange medium used for the interchange of vari- ous types of fault, test, or simulation data for electrical power systems is defined. Sources of transient data are described, and the case of diskettes as an exchange medium is recommended.Issues of sampling rates, filters, and sample rate conversions for transient data being exchanged are discussed. Files for data exchange are specified, as is the organization of the data. A sample file is given.
This standard describes methods for performing tests specified in IEEE Std C57.12.00-1993 and other standards applicable to liquid-immersed distribution, power, and regulating transformers. It is intended for use as a basis for performance, safety, and the proper testing of such transformers. This standard applies to all liquid-immersed transformers except instrument transformers, step-voltage and induction voltage regulators, arc furnace transformers, rectifier transformers, specialty transformers, grounding transformers, and mine transformers. Transformer requirements and specific test criteria are not a part of this standard, but are contained in appropriate standards, such as IEEE Std C57.12.00-1993 , ANSI C57.12.10-1988 , IEEE Std C57.12.20-1996 , ANSI C57.12.40-1994 , or in user specifications.
The purpose of this standard is to provide test procedure information.
