Energy Meter International Recommendation IR46 Expert Seminar Held

Introduction: China is a large producer of electric energy meters. The revision of IR46 will have a great impact on the measurement, production, and use of electric energy meters in China; therefore, as one of the member states of OIML, the representatives of China's experts in the TC12 meeting will Fully reflect the actual situation of China's electricity meter production, but also in line with the amendment of national interests.

Commissioned by the Metrology Division of the General Administration of Quality Supervision, Inspection and Quarantine, the National Electromagnetic Metrology Technical Committee has fully solicited opinions from electric energy measurement research institutes, electric power research institutes, production companies, and user representatives, and on June 17th at the China Institute of Metrology A CD5 Expert Seminar was held for the draft International Energy Recommendation IR46 Document No. 5. Director of the Metrology Division of AQSIQ Chen Hong attended the seminar. The meeting was chaired by Lu Zuliang, chief researcher of China Metrology Institute and chairman of the National Electromagnetic Metrology Technical Committee. A total of 24 experts from metrology and technical organizations, major electric power institutes, and electric energy meter manufacturing companies attended the conference.

According to the introduction of the chairman Lu Zuliang, the international proposal for electric energy meter IR46 is a technical document drafted by the 12th Technical Committee of the International Legal Organization OIML (abbreviation: TC12), which provides recommendations for the approval of the new design and production of electric energy meters. The important part of legal measurement. Since 2002, TC12 has organized member states to make several modifications to the IR46 document. China is a major producer of electric energy meters. The revision of IR46 will have a great impact on the measurement, production, and use of electric energy meters in China; therefore, as one of the member countries of OIML, China’s expert representatives will be able to fully reflect on the previous TC12 meeting. The actual situation of electric energy meter production in China is also in line with the amendment of national interests.

OIML, an international legal organization for measuring the legal system, will hold a TC12 meeting in London from June 22nd to 24th to discuss and revise the IR46CD5 document. At that time, China will send expert representatives to attend the TC12 meeting.

To this end, after receiving the draft IR46CD5 document from OIML in early 2011, the National Commission for Electromagnetic Measurement conducted extensive solicitations for domestic electric energy measurement research institutes, electric power research institutes, production companies, and user representatives. A total of 99 items were received. Feedback. The expert discussion will discuss, collate and summarize the feedback one by one to form the final draft; the draft will be provided to the representatives of Chinese experts participating in the TC12 International Conference as an important reference for their speeches.

At the meeting, Director Chen Hong of the Metrology Division of the General Administration of Quality Supervision, Inspection and Quarantine made a statement. She pointed out that the Metrology Division is very concerned about the measurement of electrical energy, and affirmed the National Electromagnetic Survey Committee’s extensive solicitation of opinions from all parties. She pointed out that the revision of the IR46 file places higher requirements on the electric energy measurement used by China's power supply, production enterprises, and users; at present, there are also some problems in China's domestic electricity meter quality supervision. It is hoped that the participating experts will discuss feedback opinions. Provide strong technical support for effective government supervision and decision-making.

Representatives from the State Grid Corporation of China and the National Electrical Instrument Standardization Technical Committee also stated that the revision of the IR46 document will have an important impact on the formulation of the mandatory regulations for the production of electric energy meters and electric energy meters in China, and will be seriously discussed, summarized, and summarized. The feedback will be a true and comprehensive reflection of the actual situation of China's electricity meter production, and play an important role in safeguarding national interests.
