內容簡介：
This book is inspired by the Gas Insulation and Electrical Apparatus course taught at the University of Chinese Academy of Sciences (UCAS). It is structured into two main sections:Insulation Gases and Fault Diagnosis of Electrical Apparatus. The Insulation Gases section focuses on sulfur hexafluoride (SF6) and the environmentally friendly alternative C4F7N，incorporating the latest research by scientists and engineers worldwide. Key topics include insulation performance， partial discharge， decomposition characteristics， and gas-solid compatibility. The Fault Diagnosis section explores innovative condition monitoring and diagnosis technologies for high-voltage electrical apparatus， leveraging optics， acoustics， and chemistry. These advancements equip high-voltage apparatus with sensory capabilities akin to sight， hearing， smell， taste， and touch. By integrating multidisciplinary perspectives， this book examines environmental sustainability， sensing， and detection in smart grids. A standout feature is its systematic approach to practical challenges in optical spectrum analysis， quantum chemistry calculations， and molecular design/synthesis， making it especially valuable for readers seeking real-world solutions in smart grid applications. 來源：香港大書城megBookStore,http://www.megbook.com.hk
Serving as both a graduate-level textbook and a key academic reference， this book highlights cutting-edge research and technological advances in advanced sensors and optical instruments for the power industry. It is an essential resource for researchers， engineers， and graduate students in electrical power engineering， optical/acoustic engineering， and chemical engineering.
