Overvoltage protection of AC electrical devices and lightning protection of buildings are a relatively grand subject on which extensive theoretical explanations are elaborated in various standards and manuals. Different designers have different understandings on how to implement the specification requirements into practical applications. Combining with actual engineering practices, we elaborate on the parts that should be paid attention to and the points to be discussed. This article mainly focuses on the actual practices of lightning protection and grounding.
