The Impact of Pressure on Electric Arcs Switch-off

Electrical Characterization and Modeling of High Frequency Arcs for Higher Voltage Aerospace Systems

“…The dissipated mean arc energy increased for higher currents and lower pressures which is not the result of a higher arc voltage per unit length but due to the arc elongation. Investigations in [9] and [10] for DC arcs at 540 V and a current range of 10 to 100 A, showed a non-linear increase of arc dissipated energy with system voltage and an unclear variation of energy as a function of pressure.…”
