Features: This book is the "Prevention and Detection of Electricity Theft" volume of the "Electricity Inspection Qualification Training Textbook." The book consists of 6 chapters, primarily introducing the general concepts of electricity theft and its investigation, the nature of electricity theft behavior and legal aspects, analysis of electricity theft methods, basic techniques, and behavior detection. It covers the analysis of meter wiring, correct wiring, combined wiring, incorrect wiring, and the calculation of corrected energy. The book also provides case studies on electricity theft methods, the calculation and analysis of metering errors, load testing methods, electric heater and hairdryer testing methods, capacitor testing methods, and bulb testing methods, along with the detection of metering devices and abnormal error analysis. Additionally, it discusses requirements for preventing electricity theft, specialized metering cabinets (boxes), sealing distribution transformer outlets to metering conductors, anti-tampering seals, two-way metering or reverse-flow meters, standardized installation and wiring, converting three-phase four-wire low-voltage lines to three-element meters, and converting three-phase three-wire lines to three-element meters. The book also covers the installation of leakage protectors in low-voltage systems, the configuration of voltage loss indicators or protection for TV circuits, anti-theft meters or devices, prohibiting cross-phase electricity use among single-phase users, illegal connections and unauthorized metering, and modifications to meter exteriors. It also includes the latest developments in anti-electricity theft technologies and organizational measures, such as three-tier anti-theft management, meter reading supervision, meter reading card review, the installation and replacement of metering devices, and electricity detection systems. Finally, it outlines requirements for electricity theft investigation methods, including direct inspection methods, energy consumption inspection methods, instrument inspection methods, economic analysis methods, and precautions. The book concludes with the performance of six new anti-electricity theft technology products.
