Abstract
In this paper a very sensitive device allowing the measurement of the forces exerted on an electrode by an electric arc is presented. The device principle is based on the use of a piezo-electric transducer. The calibration of the device is explained and experimental results are presented on the force exerted on various electrode materials (Ag and AgSnO2) for cathodes and for anodes. Force measurements have also been realised for various cover gases (air and argon), for various electrode gaps and for various arc current pulse durations, showing the relevance of such a diagnostic means for an electric arc.
