6、letely revised. A joint IEEE/IEC task force developed a revised approach to capacitance current switching standardization. IEC has published this task forces work as part of IECs new circuit breaker standard, designated IEC 62271-100. IEC 62271-100 replaces the old IEC 56. In the interest of harmoni
7、zation of high-voltage circuit breaker standards, a joint meeting of the IEC 17A, the IEEE/PES Switchgear Committee, and the IEEE/PES Substations Committee was held in Vienna VA, in May 1995. One of the outcomes of that meeting was a decision to form a joint IEEE/IEC task force to revise the standar
8、ds for capacitance current switching. The task force was given the IEC designation “IEC SC17A WG21 TF10.” It was agreed that the work of this task force (TF10) would serve as the basis for capacitance current switching standards in IEC and IEEE. The task force had two 2-day meetings, one in Clamart,
9、 France in September 1995 and one in Berlin Germany 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 IEC 62271-100 (formerly IEC 56) published in May 2001. The IEEE version is comprised o
10、f IEEE Std C37.04a , IEEE Std C37.09a, and a revised set of tables in ANSI C37.06. Slight modifications to the IEC version have been made to reflect North American practice. Additionally, slight modifications to the text have been made for the North American reader, such as “Earth” is replaced by “G
11、round.” Most of the text is the same and certain usage may be unfamiliar, but is understandable to the discriminating reader. In keeping with IEC Circuit Breaker Standard philosophy, the capacitance current switching ratings have been “unbundled.” A “basic” circuit breaker has either an overhead lin
12、e switching rating (outdoor circuit breaker), or a cable switching rating (indoor circuit breaker) Capacitor bank ratings, both single bank and back to back, or additional OH or cable ratings must be specified separately. Three classes of circuit breaker regarding restriking performance are specifie
13、d. “Class C0” has a probability of restrike up to one restrike 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 a restriking performance similar to the old “definite pur
14、pose circuit breaker” defined in IEEE Std C37.04- 1979 and is called “low probability of restrike.” Class C2 is intended to have a very low probability of restriking, about 1/10 or less than that of a class C1 circuit breaker. A probability of restrike classification is applicable to each capacitanc
15、e current switching rating. For circuit breakers rated 362 kV and above, a single phase test voltage factor of 1.4 (recovery voltage of 2.8 p.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 lon
16、g transmission lines and low coefficient of grounding, common in North 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 same 1.4 single phase test voltage fac
17、tor is required for all capacitance current switching duties. This is to allow for the many ungrounded systems that exist at 72.5 kV and below. IEC 62271-100 requires this only at R. W.
