Arc motion and gas flow in current limiting circuit breakers operating with a low contact switching velocity [PDF]

, 2002
Arc motion in low voltage (240 VAC) high current (10/sup 3/-10/sup 4/A.) current limiting-circuit breakers is dominated by arc root mobility. The mobility is influenced by the gas flow and gas composition in the contact region, but there is little ...

Arc Plasma Propagation and Arc Current Profiles [PDF]

IEEE Transactions on Plasma Science, 2019
When electrical arcs occur in space, a plasma expands away from the arc-site, neutralizing adjacent surfaces (a current), and causing a current to be produced at the arc-site (source of neutralization current). The speed of this plasma expansion depends on the plasma species, which in turn depend on the ionizable materials near the initial ...

Measurement of velocity and diameter of tungsten particles produced by arcing using high-speed video

Nuclear Materials and Energy
Arcing is a mechanism of dust production and erosion in fusion devices. The masses and velocities of tungsten (W) particles produced by arcing is of special interest given that W is used as wall material in current experimental devices and is planned for
