According to the notice of the National Instrument Transformer Standardization Technical Committee "Full Mutual Standards Committee Secret Word [2021] No. 13", according to the arrangement of the National Instrument Transformer Standardization Technical Committee 2021 standard system and revision work plan, the secretariat of the standard Committee is currently organizing GB/T 20840.11 "Instrument transformer Part 11: Supplementary Technical Requirements for Low power passive Voltage Transformers (modified to adopt IEC 61869-11:2017).

        According to the preliminary preparation, the secretariat of the Standard Committee, after research, is scheduled to hold a meeting in Xining, Qinghai Province, from July 26 to July 29, 2021, to study and discuss the relevant technical content of the translation of IEC 61869-11:2017, and determine the formulation principles of GB/T 20840.11.

        In addition, in order to promote GB/T 22071.2-2017 Transformer Test guidelines Part 2: Further implementation and implementation of electromagnetic voltage transformer, during the meeting, experts in the field of transformer test will be invited to promote GB/T 22071.2-2017, and in combination with the actual work situation, the precautions in the implementation of the standard are highlighted. At the same time, during the meeting, the content of transformer product model preparation in JB/T 3837-2016 "Transformer Product model preparation Method" will be discussed, and comments for modification will be widely solicited. All relevant units may appoint relevant personnel to attend the meeting at that time.
