Motion studies of high current arcs using an optical fibre array imaging system
Motion studies of high current arcs using an optical fibre array imaging system
This paper presents an integrated portable measurement system for the
study of high speed and high temperature unsteady plasma flows such as those
found in the vicinity of high current switching arcs. The system permits direct and
non-intrusive measurement of arc light emission images with a capture rate of 1
million images per second (1MHz), and 8 bit intensity resolution. Novel software
techniques are reported to measure arc trajectories. Results are presented on single
high current (2kA) discharge events where the electrode and arc runner surfaces are
investigated using 3D laser scanning methods; such that the position of the arc roots
on the runner can be correlated to the measured trajectories. The results show
evidence of the cathode arc root stepping along the arc runners

Abstract
This paper presents an integrated portable measurement system for the
study of high speed and high temperature unsteady plasma flows such as those
found in the vicinity of high current switching arcs. The system permits direct and
non-intrusive measurement of arc light emission images with a capture rate of 1
million images per second (1MHz), and 8 bit intensity resolution. Novel software
techniques are reported to measure arc trajectories. Results are presented on single
high current (2kA) discharge events where the electrode and arc runner surfaces are
investigated using 3D laser scanning methods; such that the position of the arc roots
on the runner can be correlated to the measured trajectories. The results show
evidence of the cathode arc root stepping along the arc runners
