IEEE - IEEE 295 - STANDARD FOR ELECTRONICS POWER TRANSFORMERS Organization: IEEE
Date: 1969-01-01
Description: PURPOSEThe character and applications of transformers used in electronic circuits are enough different from other categories so that none of the existing Standards does a satisfactory job.
IEEE - IEEE C57.13.6 - STANDARD FOR HIGH-ACCURACY INSTRUMENT TRANSFORMERS Organization: IEEE
Date: 2005-09-22
Description: There are two important differences about these new accuracy class definitions as they apply to routine current transformer test requirements: a) A low current test is required at 5% of rated current (0.25 A secondary), in lieu of the 10% of rated current test specified in IEEE Std C57.13. This test point corresponds with the light load test point of transformer rated electromechanical and solid state electricity meters as specified in ANSI C12.20.
IEEE - ANSI C57.12.55 - TRANSFORMERS USED IN UNIT INSTALLATIONS, INCLUDING UNIT SUBSTATIONSCONFORMANCE STANDARD - REPLACES NEMA C57.12.55-1987 Organization: IEEE
Date: 1987-01-01
Description: This document refers to the proposed revision of American National Standard for Dry-Type Transformers, ANSI/IEEE C57.12.01-1979 (now in preparation).This document includes Appendixes A and B, outlining procedures recommended for qualifying insulation systems; related material is covered in American National Standard Test for Thermal Evaluation of Insulation Systems for Ventilated Dry-Type Power and Distribution Transformers, ANSI/IEEE C57.12.56-1984.
ASTM D4652 - STANDARD SPECIFICATION FOR SILICONE FLUID USED FOR ELECTRICAL INSULATION Organization: ASTM
Date: 2005-10-01
Description: 2 2IEEE C57.111, IEEE Guide for Acceptance of Silicone Insulating Fluid and its Maintenance in Transformers is published by the Insulating Fluids Subcommittee of the IEEE Power Engineering Society Transformers Committee.
IEEE - IEEE 315 - GRAPHIC SYMBOLS FOR ELECTRICAL AND ELECTRONICS DIAGRAMS (INCLUDING REFERENCE DESIGNATION CLASS DESIGNATION LETTERS) - CSA Z99-75; INCLUDES SUPPLEMENT TO ANSI Y32.2-75 AND IEEE 315-75 Organization: IEEE
Date: 1975-09-04
Description: This American National Standard is a revision and expansion of American National Standard Graphic Symbols for Electrical and Electronics Diagrams, Y32.2-1970 (IEEE Std 315-1971).A variety of specialized symbols originally used for aircraft applications have been added to make this standard more comprehensive.
