Abstract :
The arc development in the liquid metal current limiter, whose operation is based on the fluid pinch effect, is researched by experimental methods, including high-speed photography. The pre-arcing time and arc voltage are related to the channel diameter and prospective current. The electrode erosion is analyzed, and an efficient method is proposed to reduce this phenomenon.
