The Arc Eliminator is a kind of ultra-high speed earth switch and it is structural part of an Arc Protection System. If an arc accident occurs in a power apparatus such as switchgears, the Arc Eliminator operate and fault current is bypassed to ground. Accordingly, an arc is extinguished and apparatus and people are protected. For this movement, it requires ultra-high speed mechanism, so in this study, we choose the electromagnetic repulsive mechanism, Thomson Coil. The speed of developed mechanism is up to 10 m/s and operation time is below 3.5 ms.
