Abstract
As critical overvoltage protection devices for HVDC converter valves,arresters are essential for ensuring the safe and stable operation of converter valves.The voltage waveforms applied to converter valve arresters differ from the power-frequency voltages of conventional AC systems.Meanwhile,tempo-rary overvoltages occurring in converter stations lead to more complex operating conditions for such arres-ters.Significant differences in service conditions and operating characteristics make the design criteria of converter valve arresters distinct from those of conventional arresters.The main purpose of this article is to introduce the development and commissioning of converter valve arresters,and to explain the key cha-racteristics that must be studied and the relevant parameters that must be considered in their design.关键词
