7、served. Introduction This introduction is not part of IEEE Std C57.21-2008, IEEE Standard Requirements, Terminology, and Test Code for Shunt Reactors Rated Over 500 kVA. IEEE Std C57.21 was first published in 1971. It was subsequently revised in 1981 and 1990 and reaffirmed in 1995 and 2004. The cur
8、rent revision process has focused on the following: a) Annex A (normative) has been added to cover the specific requirements for dry-type air-core thyristor-controlled shunt reactors, which are an important component of static var compensator systems. Specific clauses, subclauses, tables, etc., in t
9、he main body of IEEE Std C57.21-2008 are referenced regarding specification and test code. Other aspects of specification and test code are covered in Annex A. b) Annex B (informative) has been added to provide background information on dielectric stresses imposed on shunt reactors during switching.
10、 The objective of Annex B is to provide guidance regarding the application and design of shunt reactors, especially in consideration of the significant switching duty and the associated repetitive dielectric stresses. As a consequence of the switching stresses seen by shunt reactors, reduced BIL (ba
11、sic lightning-impulse insulation levels), which is common practice for power transformers, are no longer recommended and are not included in Table 5. Formal input regarding the content of this annex was requested of the IEEE Switchgear Committee and was provided. Input was also received from members
12、 of IEC MT32 on Inductive Load Switching. c) Table 5A and Table 5B in the previous version (IEEE Std C57.21-1990) have been combined into one table as Table 5 (insulation levels of shunt reactors). Separate tables for dry-type and oil-immersed shunt reactors were not deemed necessary as test levels
13、are network-dependent and are independent of shunt reactor technology. Maximum system voltage is introduced to be consistent with terminology in the IEC reactor standard (see IEC 60076-6:2007 B18).aNotice to users Laws and regulations Users of these documents should consult all applicable laws and r
