6、 forcedeveloped a revised approach to capacitance current switching standardization. IEC has published this taskforces work as part of IECs new circuit breaker standard, designated IEC 62271-100. IEC 62271-100replaces the old IEC 56. In the interest of harmonization of high-voltage circuit breaker s

7、tandards, a joint meeting of the IEC 17A,the IEEE/PES Switchgear Committee, and the IEEE/PES Substations Committee was held in Vienna VA, inMay 1995. One of the outcomes of that meeting was a decision to form a joint IEEE/IEC task force to revisethe standards for capacitance current switching. The t

8、ask force was given the IEC designation “IEC SC17AWG21 TF10.” It was agreed that the work of this task force (TF10) would serve as the basis for capacitancecurrent switching standards in IEC and IEEE. The task force had two 2-day meetings, one in Clamart,France in September 1995 and one in Berlin Ge

9、rmany in December 1995.The task force was comprised of the following:The work of the above task force has been incorporated into the new IEC circuit breaker standard IEC62271-100 (formerly IEC 56) published in May 2001. The IEEE version is comprised of IEEE StdC37.04a, IEEE Std C37.09a, and a revise

10、d set of tables in ANSI C37.06. Slight modifications to the IECversion have been made to reflect North American practice. Additionally, slight modifications to the texthave been made for the North American reader, such as “Earth” is replaced by “Ground.” Most of the text isthe same and certain usage

11、 may be unfamiliar, but is understandable to the discriminating reader. In keeping with IEC Circuit Breaker Standard philosophy, the capacitance current switching ratings havebeen “unbundled.” A “basic” circuit breaker has either an overhead line switching rating (outdoor circuitbreaker), or a cable

12、 switching rating (indoor circuit breaker) Capacitor bank ratings, both single bank andback to back, or additional OH or cable ratings must be specified separately. Three classes of circuit breaker regarding restriking performance are specified. “Class C0” has a probabilityof restrike up to one rest

13、rike per operation, and its capacitance current switching performance can be com-pared to the former “general purpose circuit breaker” defined in IEEE Std C37.04-1979. “Class C1” has arestriking performance similar to the old “definite purpose circuit breaker” defined in IEEE Std C37.04-1979 and is

14、called “low probability of restrike.” Class C2 is intended to have a very low probability ofrestriking, about 1/10 or less than that of a class C1 circuit breaker. A probability of restrike classification isapplicable to each capacitance current switching rating. For circuit breakers rated 362 kV an

15、d above, a single phase test voltage factor of 1.4 (recovery voltage of 2.8p.u.) is required for the overhead line switching test duties. (This is an option in IEC 62271-100.) The pur-pose of this requirement is to acknowledge the long transmission lines and low coefficient of grounding,common in No

16、rth America. This is an increase from the 1.2 single phase test voltage factor (2.4 p.u. recov-ery voltage) requirement in IEEE Std C37.04-1979. For circuit breakers rated 72.5 kV and below the same1.4 single phase test voltage factor is required for all capacitance current switching duties. This is

17、 to allowfor the many ungrounded systems that exist at 72.5 kV and below. IEC 62271-100 requires this only atR. W. Alexander (IEEE)D. Dufournet (IEEE and IEC)R. Jeanjean (IEEE and IEC)H.

NOTE 1The probability is related to the performance during the series of design tests.NOTE 2Phenomena occurring after a restrike or a re-ignition event are not representative of service conditions as thetest circuit does not adequately reproduce re-ignition/restrike energy or the post-event voltage conditions.NOTE 3A circuit breaker can be class C2 for some
