Features: This book is written for training engineering technicians engaged in overvoltage protection and insulation coordination of power systems, as well as serving as a reference for scientific research, design, higher education, and manufacturing professionals. The book is divided into twelve chapters and sixteen appendices, with rich content, clear concepts, and explicit viewpoints. It provides in-depth discussions on major practical issues, such as:
- Selection of lightning parameters in lightning protection engineering
- The protective effect of lightning rods (wires)
- Requirements for lightning protection grounding resistance (actually impedance)
- Definitions, terminology, and testing of some important parameters of AC non-gapped metal oxide arresters (actually nonlinear resistors—abbreviated as WGMOA), as well as their interrelationships under different operating conditions and service life (in years) evaluation methods
- Selection of neutral grounding methods for 3~66kV power grids and protection against lightning and internal overvoltage
- Selection of lightning protection measures for overhead transmission lines at 110kV and above, lightning withstand analysis, and the basis for allowable lightning-induced trip counts according to circuit breaker operation resource criteria
- Optimization of lightning protection layout and lightning withstand evaluation methods for power generation and transformation equipment
- The of lightning protection cables for directly connected rotating machinery
- Protection against internal overvoltage in power grids at 110kV and above, especially the protection of ultra-high frequency operational overvoltage in GIS, etc.
