Study of the movement of an electric breaking arc at a low voltage

Abstract

The experimental study of the evolution of the electric arc, with inverse movements is made possible with good accuracy thanks to the use of microcoils which detect the induction created by the electric circuit. The simulation of the movement of the arc and of the magnetic induction against time allow the authors to explain satisfactorily the measurements made during the rising phase.

SF6 post‐arc recovery characteristics

“…The kinematics of magnetically blown arcs has also been studied either by using optical fibers [14], or by sensors made of micro coils [15], or by means of high-speed cinematography [16,17].…”

Position location of a filamentary arc using a tristimulus chromatic technique

“…These examples indicate that it is important to determine the location of the arc filament in order to comprehend the performance trends of such arc devices. Several electromagnetic [7][8][9][10] and optical detection methods have been proposed. With regard to optical methods, high-speed cameras, high-speed video cameras and optical multichannel analysers have been utilized for such measurements [11][12][13][14].…”
