19、SI C76.1-1943 throughANSI C76.1-1964. In August of 1968, the ANSI C76.1 Committee decided to divide the standard into threeparts. The first (ANSI C76.1) covers general requirements and test procedures, the second (ANSI C76.2)covers explicit ratings and dimensions, and the third (ANSI C76.3) covers t

20、he application guide. ANSI C76.2-1977/IEEE Std 24-1977 incorporated changes that includeda) Adding dual current ratings for 115196 kV insulation class bushings for transformers and circuitbreakersb) Adding voltage class ratings for 362800 kV with wet switching impulse test values and coordina-tion w

21、ith switching surge sparkover values of arrestersc) Adding and updating acceptance limits for partial discharge, power factor, and capacitance ANSI/IEEE Std 24-1984 incorporated revisions in Table 1 and Table 9 to make them compatible with theconcept of IEEE Std 262B-1977.IEEE Std C57.19.01-1991, sp

22、onsored by the IEEE Transformers Committee, incorporated changes to makeit compatible with the new test procedures established by its companion standard, IEEE Std C57.19.00-1991. These changes included Table 9 and Table 10. During the work on the latest revision, IEEE Std C57.19.01-2000, major chang

23、es have been incorporated.These changes were the result of feedback from the Edison Electric Institute (EEI), original equipment man-ufacturers (OEMs), and users. The ratings were standardized in an effort to create fewer ratings and reducethe need for large inventories of spare bushings, which have

24、 accumulated from decades of special designs.Bushings in inventory incur a large tax burden from accruing bushing costs in 25 y. In addition, the require-ment for bushings for application on new bulk oil circuit breakers ceased because these breakers were nolonger being produced. The working group r

25、eviewed this information and agreed to revise the standard toreduce the number of ratings, promote standardization, improve bushing characteristics for new transform-ers, and achieve overall cost improvements. This work has resulted in the reduction of designs/ratings from56 to 21. These changes inc

26、lude the following: Table 1, Electrical insulation characteristics. The number of voltage classes has been reduced from19 to 7 to cover the 34.5765 kV voltage range. Voltage/insulation classes, which were a part ofTable 1 in IEEE Std C57.19.01-1991, but not included in Table 1 of this standard, are

27、included inAnnex A to provide information on replacement bushings. The system voltage designation has beenchanged to indicate nominal rating in conformance with transformer standard IEEE Std C57.12.00-1993. The BIL rating for each voltage class is based on the highest BIL specified in IEEE StdC57.12

28、.00-1993 for the same voltage class. A BIL of 2050 kV has been adopted for 756 kV rating. Acolumn on creepage distance has been added to provide information on values corresponding to con-taminated (heavy) environments as per IEEE Std C57.19.100-1995. Table 2, Dimensions for bushings up to 69 kV. Cu

29、rrent ratings of 400/1200 A, 2000 A, 3000 A, and5000 A have been standardized. A current transformer pocket length of 534 mm (21 in) has beenstandardized for these ratings. The bottom-end length has been standardized in each voltage class.The top terminal diameters have been standardized at 1.5 in f

30、or current up to 2000 A, 2 in for 3000 A,and 4 in for 5000 A rating. The bottom terminal configuration for ratings 2000 A and above havebeen changed from threaded stud to two- and four-hole bladed configurations similar to those inNEMA CC1-1993. Information on transformer and circuit breaker interch

Table 3, Dimensions for bushings above 69 kV. Current ratings of 800/1200 A, 2000 A, and 3000 Ahave been stan

32、dardized. A current transformer pocket length of 584 mm (23 in) has been standard-ized for these ratings. The bottom-end length has been standardized in each voltage class. The “D”diameter for the 196/230 kV rating has been reduced. The top terminal diameters have been stan-dardized at 1.5 in for cu

33、rrent up to 2000 A, and 2 in for 3000 A rating. Dimensions for 500 kV and765 kV ratings have been added. Information on TBI and breaker ratings has been taken out. Thefootnote on draw-lead application has been revised to define the current-carrying limit. Table 4, Cantilever test requirements. The t

34、able has been simplified and expanded to include infor-mation on bushings above 345 kV. The permanent deflection at the bottom end has been revised toreflect transformer bushings requirement. Information on TBI and breaker ratings has been taken out. Table 5, Partial discharge limits. The requiremen

35、t at maximum L-G voltage has been taken out. Table 6, Power factor and capacitance limits. The limit for power factor for oil-impregnated, paper-insulated bushings has been lowered from 0.55% to 0.50%. Also, the power factor change limits forthese bushings have been changed from +0.02/0.06 to +0.02/

36、0.04. In addition, metric units have been adopted as primary units followed by inch-pound-based units inparentheses. Units/dimensions that are dependent upon inch-sized dies/tools have not been convertedto metric units. Threads/inch and flange bolt hole diameters fall into this category. Annex A, El

37、ectrical insulation characteristics. This annex has been added to include the insulationcharacteristics for ratings, which were a part of IEEE Std C57.19.01-1991, but not included in Table1 of this standard.
