Abstract
This paper presents a protection device covering broad range of currents in LVDC distribution. As direct current has significantly different electrical characteristics compared to alternate current, it is important to implement protection strategies. To fulfil this requirement, this paper firstly introduces design architecture of sensing unit, shunt embedded and override sensor connected to digital trip system. Based on current measurement system, we focus on designing arc splitting component called “Arc Chute”. To verify this component, various tests according to IEC 60947-2 were applied to DC ACB (Air Circuit Breaker).
