To aid in the interpretation and application of the impulse testing requirements of the IEEE Standard Test Codes for Transformers. Purpose This guide is written primarily for power transformers, but it is also generally applicable to distribution and instrument...
This standard covers certain mechanical requirements for liquid-immersed distribution transformers with respect to tank strength, as well as static and dynamic tank pressure mitigation. This standard can be applied to various tank configurations for distribution transformers. This...
Foreword (This Foreword is not part of Amencan National Standard C57.12.55-1987.) The High Voltage Apparatus Coordinating Committee (HVACC) was established July 24, 1972 by the Electrical and Electronic Technical Advisory Board (now superseded by the Electrical and Electronic Standards Management...
This Guide contains general and specific recommendations for grounding of the secondary circuits and cases of instrument, i.e., potential and current, transformers in all types of installations. These recommendations apply to all instrument transformers irrespective of the value of...
This recommended practice is issued as a supplement to IEEE Std C37.06 for high-voltage circuit breaker applications where the transient recovery voltage (TRV) peak is higher and/or its rise to the crest value occurs more rapidly than those specified in IEEE Std C37.06. Purpose The...
This guide applies to transformers referenced in IEEE Std C57.12.00 as Categories I, II, III, and IV.1 It sets forth recommendations essential for the application of overcurrent protective devices applied to limit the exposure time of transformers to short-circuit currents (see...
This guide for dry-type transformer through-fault current duration applies to dry-type distribution and power transformers built in accordance with IEEE Std C57.12.01™.1 Purpose This guide sets forth recommendations believed essential for the application of overcurrent...
This guide contains general and specific recommendations for grounding current and voltage transformer secondary circuits and cases of connected equipment. The practices recommended apply to all transformers of this type, including capacitive voltage transformers and linear...
The intent of this guide is to assist the working groups within the IEEE Transformers Committee; thus, specific examples were taken from the transformer-related standards. It should be recognized that identification of general principles and procedures could have broader...
This standard provides a basis for electronic reporting of transformer test data on liquid-immersed distribution transformers. This standard defines how to format and report the standard test data when electronic reporting is specified. In addition, it defines an extended set of data...
