Features: According to the provisions of the "Electricity Law" and the "Management Measures for Electricity Inspection," "For acts that endanger the safety of power supply and electricity use or disrupt the order thereof, power supply enterprises have the right to prevent such acts. Inspectors carrying electricity inspection certificates have the right to enter user premises for safety inspections." In accordance with the requirements of the Ministry's notice on "Issues Concerning the Qualification Recognition of Electricity Inspection Personnel" (Comprehensive [1998] No. 7), to ensure the safe and stable operation of the power grid, maintain normal power supply and electricity use order, protect the legitimate rights and interests of both power supply and electricity use parties, and effectively fulfill the electricity inspection tasks stipulated in the "Electricity Law," it has been clearly stipulated that the qualifications of electricity inspection personnel at levels one, two, and three must be assessed and recognized. Therefore, to improve the quality of the electricity inspection team, ensure that electricity inspection personnel possess the corresponding inspection capabilities and standards, and guarantee that electricity inspection work is carried out legally and effectively, a set of "Electricity Inspection Qualification Assessment Teaching Materials" (5 volumes) has been organized and compiled to meet the training and qualification recognition needs of power supply enterprises in various provinces and networks. This book is the "Electricity Inspection Qualification Assessment Training Teaching Material (Electric Energy Metering)" volume, comprising a total of 6 chapters. It mainly introduces laws and regulations related to electric energy metering, types and contents of electric energy metering devices, types of electric meters and their nameplates, technical aspects of induction, static, multifunction, prepaid, and wide-range electric meters, current and voltage transformer wiring, components and configurations of metering cabinets (boxes), five categories of electric energy metering devices and their adjustment contents and examples, determination of metering plans, accuracy grade configuration and errors, selection of transformers and secondary circuit selection, wiring methods, configuration principles, design review, ordering and acceptance testing, asset management, installation and acceptance, operation management, responsibility division, fault handling, operation monitoring of main and auxiliary electric meters, on-site inspection, periodic verification (rotation), sampling verification, and transportation, requirements for certification management, types and production of certifications, use of certifications, implementation requirements for metering seals, color markings for metering instruments, the purpose, technical requirements, and various types of automatic meter reading systems, as well as electric meters used in conjunction with automatic meter reading systems. It also covers correct and combined wiring, incorrect wiring, wiring inspection, and calculation of additional/adjusted electricity, etc. Finally, it includes technical management, installation and wiring, verification, and use procedures for electric energy metering devices. This set of teaching materials can be used as the dedicated assessment material for electricity inspection position training and qualification recognition by power supply companies in various provinces and networks, as well as reference materials for position training in electricity marketing, electric energy metering, and new installation and connection in power supply enterprises.
