Foreword
According to the requirements of Document Jianbiao [2002] No. 85 issued by the
Ministry of Housing and Urban-Rural Development of the People 's Republic of China-
"Notice on Printing the Development and Revision Plan of National Engineering
Construction Standard in 200 I ~2002", this Code was revised based on the original national
standard "Code for Design of Electrical Measuring Device of Power System" GBJ 63-90 by
Southwest Power Design Institute of China Power Engineering Consulting Group Corporation
and together with the relevant organizations.
In the revision procedure, the code revision team carried out an extensive investigation,
conscientiously summed up the experience since the implementation of the original Code,
extensively solicited the views of relevant organizations nationwide, and finally , finalized
after examination.
This Code comprises I 0 chapters and 3 Appendixes, and the main contents include.
general provisions, terminologies and symbols, electronic measuring device, energy metering,
electrical measuring of DC converter station, measuring of computer supervisory control
system, electrical measuring transducer, electric current and potential transformer for
measuring, measuring small wiring and installation of devices.
The main revisory contents of this Code were. adjusted the scope of application of this
Code; increased new requirements for electrical measuring and energy metering after
adopting computer supervisory control system and integrated plant; increased electrical
measuring content of static compensated series compensating gear; increased public grid
harmonic monitoring content; increased electrical measuring content of DC converter station.
Ministry of Housing and Urban-Rural Development of the People's Republic of China is
in charge of the administration of this Code, Standardization Center of China Electricity
Council is responsible for the current supervisory work, and the Southwest Power Design
Institute of China Power Engineering Consulting Group Corporation is in charge of the
explanation of the specific technical contents. All relevant organizations are kindly requested
to sum up and accumulate your experiences in actual practices during the process of
implementing this Code. The relevant opinions and advice, whenever necessary, can be
posted or passed on to Southwest Power Design Institute of China Power Engineering
Consulting Group Corporation (Address. No. 18 Dongfeng Road, Chengdu City, Sichuan
Province, 610021, China), so as to be used as a reference for future revision.
