Abstract

Abstract : High‐voltage DC arrester is one of the key equipment for overvoltage protection of ultra‐high voltage DC (UHVDC) transmission system. This device plays a decisive role in the insulation level of the whole process. The current distribution between resistance pieces of multi‐column parallel arresters is non‐uniform, which affects the overall energy absorption capacity of arresters. First, a real failure case of ±500 kV Xiluodu‐Nuozhadu HVDC project is introduced. Then, the analysis of the specific failure case is proposed. Finally, a corresponding model is built on PSCAD/EMTDC to study the current distribution characteristics.
