Abstract

The dominant bounce frequency of a metal particle has been proposed as a means of studying its motion. Measurements of the acoustic emission due to the particle motion in a SF/sub 6/ gas-insulated system are reported. Analysis of the data shows that there are two types of particles. For one type the bounce frequency increased with increasing voltage, whereas for the other type it decreases. Aluminium particles yield higher acoustic amplitudes than copper particles, and there is a relationship between the maximum amplitude and the mass of the particle.<>
