Features: In the process of using power cables, once an insulation fault occurs, if it cannot be promptly resolved to restore power supply, it often results in significant economic losses due to power outages and production halts. How to restore power supply as quickly as possible with the lowest maintenance costs is the primary challenge faced by power supply departments when encountering cable faults. To facilitate the rapid summary and exchange of experience in power cable fault location technology, the authors, after extensively reviewing domestic and international materials, compiled this book. This book focuses on providing detailed introductions to various effective methods for addressing different types of high-resistance faults. It also includes introductions to representative intelligent power cable fault testers widely used in China, as well as the basic working principles of auxiliary equipment such as path finders and pinpointers, for reference by electrical technicians and relevant research and production units. The book consists of seven chapters, covering preparatory knowledge for analyzing cable fault characteristics, the causes of power cable faults, the steps for locating power cable faults, preliminary testing of power cable faults, cable path detection and cable identification, precise pinpointing of cable faults, and theoretical applications with case analyses. This book is suitable for electrical technicians with secondary school or higher education levels, as well as workers with practical experience. For organizations currently equipped with various types of power cable fault testers and those with power cables but lacking such instruments, this book is an indispensable reference and experience-based guide, offering significant value for reference.
