Comparison and Analysis of IEC and GB Lightning Protection Standards on Direct Lightning Flash Protection
-
Abstract
Comparison and analysis are presented between Code for design protection of structures against lightning (GB 50057) and IEC 62350 on structures direct lightning flash protection. A corresponding relationship between two standards is made by analyzing lightning current parameters and protection measures. Comparison is described from structures classifications, risk assessment, lightning protection system etc. It introduces the hidden risk analysis of structures classifications in GB 50057. This paper discusses the reason why GB 50057 can be used in the international engineering project, and some proposals are submitted.
