Features: According to the relevant provisions of the State Electricity Regulatory Commission's "Management Measures for Electrician Network Work Permit" (Order No. 15 of the State Electricity Regulatory Commission), the Electrician Network Work Permit is implemented through a national unified examination system. The Electrician Network Work Permit is divided into three categories: low-voltage, high-voltage, and special. This book covers the high-voltage portion. During the writing process, this book closely aligns with the requirements of the "Electrician Network Work Permit Examination Outline," encompassing all key knowledge points to meet the examination needs of a broad range of candidates. The book is divided into five parts: Basic Knowledge of Power Systems, Power Transformers, High-Voltage Apparatus and Complete Distribution Equipment, High-Voltage Power Lines, Overvoltage Protection, Relay Protection and Secondary Circuits, and Electrical Safety Technology. On one hand, this book can serve as a tool for electricians to test and review during their exam preparation. On the other hand, it also takes into account practical production scenarios, explaining common production knowledge and equipment faults.
