Abstract
The most important question is how to use which kind of switch in pulsed power generation. There are many kinds of commercial closing switches, which have advantages and disadvantages. The most popular closing switch is the spark gap, but it has a disadvantage in life time, because of erosion of electrodes by arc heating. The Rotary Arc Gap (RAG) switch, especially Walkie-Edgar type RAG switch, was proposed to solve such problems in spark gap. It has a simple and special structure for arc moving caused from self-induced electromagnetic force, because moving arc makes less erosion on the electrodes. In this study we have made an Walkie-Edgar type RAG switch, tested the switching with capacitive energy storage system, and measured rotating arc speed in different peak current.
