Optical fiber imaging for high speed plasma motion diagnostics: applied to low voltage circuit breakers

By J.W. McBride, A. Balestrero, L. Ghezzi, G. Tribulato and K.J. Cross

Abstract

An integrated portable measurement system is described for the study of high speed and high temperature unsteady plasma flows such as those found in the vicinity of high current switching arcs. An array of optical fibers allows the formation of low spatial resolution images, with a maximum capture rate of 1×106 images per second (1 MHz), with 8 bit intensity resolution. Novel software techniques are reported to allow imaging of the arc; and to measure arc trajectories. Results are presented on high current (2 kA) discharge events in a model test fixture and on the application to a commercial low voltage circuit breaker
