IEC\/IEEE 62271-37-013:2021 is applicable to three-phase AC high-voltage generator circuit-breakers, hereafter called generator circuit-breakers, designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 kV and up to 38 kV.
\nThis document is published as an IEC\/IEEE Dual Logo standard.
\nThe IEEE Std C37.013\u2122-1997 (R2008) was revised and converted into the first edition of the IEC\/IEEE Dual Logo International Standard IEC\/IEEE 62271-37-013 published in 2015.
\nThis second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision.
\nThis edition includes the following significant technical changes with respect to the previous edition:<\/p>\n

    \n
  1. content has been added to address the requirements of the other components of the generator circuit breaker system;<\/li>\n
  2. requirements for the application of generator circuit-breakers in power plants with multiple generators connected to one step-up transformer have been added;<\/li>\n
  3. requirements for testing and application of Tee-OFF generator circuit-breakers have been added;<\/li>\n
  4. requirements for application of generator circuit-breakers in power plants with doubly-fed induction machines, pumped-storage power plants, and wind farms have been added;<\/li>\n
  5. the clause numbering has been aligned with the numbering in IEC 62271-1:2017;<\/li>\n
  6. the topic of reference mechanical characteristics has been revised to improve clarity;<\/li>\n
  7. the modifying effects of capacitors on the prospective TRVs for out-of-phase and load current switching has been addressed in Annex M and in Annex N with use of the tool named "GenCB TRV calculator". This tool provides the values of K<\/em>E2, RRRV<\/em>0, <\/em>K<\/em>RRRV-U, <\/em>K<\/em>RRRV-I, t<\/em>d0, K<\/em>td-U, <\/em>K<\/em>td-I, as well as the values of the parameters of the prospective TRV modified by the capacitors of the generator circuit-breaker.<\/li>\n<\/ol>\n
    This document contains attached files in the form of Excel spreadsheets ("GenCB TRV calculator"). These files are intended to be used as a complement and do not form an integral part of the document.<\/div>\n","protected":false},"excerpt":{"rendered":"
