Consensus is established when, in the judgment o

Substantial agreement means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerte

15、e iii FOREWORD (This foreword is not part of American National Standard C37.06-2000.) This standard is a revision of ANSI C37.06-1997. It reflects small editorial changes needed to coordinate with the final wording contained in the defining standards ANSI/IEEE C37.04-1999 and ANSI/IEEE C37.09-1999.
16、Some ratings have also been updated. Because this revision is primarily editorial in nature, this Foreword describes the substantive and editorial changes between this revision and the 1987 version. The format of the tables remains very much the same, except that some ratings, which had been given i
17、n the notes (sometimes on a different page from the table of preferred ratings), have been listed explicitly in the tables. The transmission voltage classes of 121 kV, 169 kV, and 242 kV have been changed to 123 kV, 170 kV, and 245 kV respectively to complete the harmonization with IEC. This harmoni
18、zation was begun when IEC adopted 550 kV and 800 kV, replacing 525 kV and 765 kV respectively. Editorial revisions in Tables 1, 2, and 3: The individual lines and columns have been identified with numbers for easy reference. The preferred ratings for transient recovery voltage maximum rated peak vol
19、tage E2 value, have been moved from the notes to the table itself for tables 1 and 2. Similarly, the maximum permissible tripping delay value (Y) has been moved from the notes to the table itself for tables 1, 2, and 3. The maximum symmetrical interrupting capability is no longer listed explicitly i
20、n the tables since it is now numerically equal to the rated short- circuit current (K=1.0). Further, the short-time current rating is also equal to the short-circuit current rating, but it is included in the title of Col. 4 in the tables. The closing and latching current is now listed as a rating (i
21、t had been a related required capability), and the preferred ratings (kA, peak) have been calculated at 2.6 times the rated short-circuit current. This has been reduced from 2.7 times in the 1987 edition to promote harmonization with other international standards. (If expressed in terms of rms total
22、 current, momentary current, the equivalent value of the closing and latching current is 1.55 times the rated short-circuit current.) Throughout this document, the term traditionally associated with the maximum value of transient or periodic wave form, “peak“ is used. Table 1The major revision in th
23、e ratings for indoor circuit breakers is that the preferred values for the rated voltage range factor K have been set to 1.0 for all indoor circuit breaker ratings. The principal reason for this change is that the capabilities of todays circuit breaker designs are better described by the K=1.0 value
24、. The user will note that an additional benefit to the K=1.0 system is that the number of notes in Table 1 are reduced by half. This change in no way affects the ratings and capabilities of circuit breakers manufactured and tested to the ratings in the 1987 edition, which should continue to be appli
