Foreword

This section GB/T 2900 Part 57. The partial modification of the use of IEC 60050-604. 1987 "International Electrotechnical Vocabulary - Part 604. Generation, transmission and distribution operations," and International Electrotechnical Commission 2003 reference document (1/1905/CD), modify some of the definitions of terms. This part of IEC 60050-604. 1987 compared, there is a technical difference. --- Modified 604-01-04,604-01-33,604-02-14,604-03-33 such definitions; --- Remove half the peak time of the entry 604-03-22 shock wave. This Part replaces GB/T 2900.57-2002 "Electrotechnical terminology Generation, transmission and distribution operations." This section compared with the GB/T 2900.57-2002 main changes are as follows. --- Modify the term entry number; --- Modified 604-01-03,604-02-34,604-02-36,604-02-37,604-04-21 such definitions; --- 604-01-15 modified the term "voltage flatness"; --- 604-03-26 modified the term "shock wave head cut off"; --- 604-01-33 modified the term "continuity of supply criterion"; --- Remove the "[operating shock wave] peak time" entry.
