Abstract: A high voltage pulse generator is provided which so interacts with the parameters of an electrostatic precipitator that excellent pulse waveforms are obtained more efficiently by using less elaborate components than heretofore required. A major feature of the invention is the charging of the pulse forming network through the high-voltage d.c. source which energizes the precipitator for charge-particulate removal.

Abstract: A triggered spark gap suitable for use with high levels of voltage and current over long periods of time generally comprising support means, a pair of insulated main electrodes disposed opposite each other on the support means so as to form a gap therebetween, first electrical means associated with the main electrodes for creating a potential difference therebetween, at least one trigger electrode defining a region having a cross-sectional thickness to width ratio greater than one, said trigger electrodes being mounted on the support means such that said region is disposed in the gap between the main electrodes, and second electrical means connecting the trigger electrode to a source of triggering and biasing potential.
