Features: Based on the second edition, this book has been revised according to the requirements of broadening knowledge, incorporating new practical content, and reducing. The book includes the following content: ① Measurement of basic dielectric parameters, such as insulation resistance (microcurrent), capacitance (dielectric constant), loss factor (dielectric spectrum), and insulation strength; ② Partial discharge measurement; ③ On-line detection and insulation diagnosis; ④ Reliability and life testing. On the basis of briefly describing the physical concepts and influencing factors of each measured parameter, the book focuses on discussing the testing principles, signal acquisition and processing, as well as methods to improve measurement sensitivity and accuracy. It also elaborates on relevant error analysis and data processing methods. This book can serve as a textbook for undergraduate and junior college students, as well as a reference for electrical and electronic product designers, manufacturers, testing technicians in industrial and mining enterprises, and insulation supervision personnel in power system operations.
