    The stress waves generated by electrical discharges within a void in polyester resin were analyzed quantitatively. The rise time of the stress transient acting against the void wall was 800 ns. The acoustic energy submitted to the solid was 3 nJ which was 0.002% of total energy released by the discharge. These values were determined by the original wave analysis in which the influence of the trans... View full abstract»

    In this paper an approximate equation for the calculation of sparkover time of a low-pressure magnetic switch is presented. The theory is based on the assumption that all of the positive ions generated in the gap are situated at the anode. The concept of the effective reduced electric field (EREF) is applied to take into account the influence of a crossed magnetic field on the discharge parameters... View full abstract»

    DC tree initiation and propagation and treeing phenomena in PMMA under ramped voltages have been investigated by a optical method using a photomultiplier and a close-up camera. The Weibull plot of the initial tree inception voltage for a positive point had a knee at about 35 kV, above which the slope was lower, while the plot for a negative point was linear. The succeeding negative streamer origin... View full abstract»

    Results of breakdown measurements in SF6 are presented using very inhomogeneous large rod-plane gaps, 50 Hz ac and impulse voltage at pressures from 0.05 to 0.6 MPa. It is shown that for both voltage forms breakdown occurs over the whole pressure range due to a transition of the discharge mechanism from streamer to leader development. It was possi ble to determine the leader inception voltage. The... View full abstract»

    The mechanism of the so called "area effect" in vacuum dis charge studies was investigated. Point-plane aluminum electrodes were used with point radius 1.5 mm and gaps between 0.5 and 10 mm. It was found that a capacitor connected in parallel with an electrode gap reduces the electrical strength in a manner similar to that observed with increasing electrode area. The capacitance was found to play ... View full abstract»
