This paper reports on the relative vulnerabilities of bare- and insulated-line conductors to hits from discharge strokes coming from sources at voltages too high to prevent flashovers, like lightning. Protection against such strokes must be based on

Purpose: To find how a spark from a positive or negative rod locates an object to connect to, or finds a weak spot in a cable insulation. Experimental: 1-2-m gap in ambient air between a rod and a horizontal wire suspended 0.25-0.5 m above ground, su

The paper treats experiments, computer simulations, and the physical explanation of the oscillatory behaviour of positive glow coronas at or below atmospheric density. Experiments show that most positive glows have ionization regions that oscillate w

This work concerns the extraction and mass spectroscopic analysis of near-thermal energy ions from coronas in 2.5–20 kPa air, using molecular- or transition-flow orifices in Al, Au, Cu, Mo, stainless steel, and composite “sandwich” foils. The e

Mass spectra of positive ions extracted from low-pressure (300-500 Pa) AC discharges to polymer surfaces show that polyethylene and polypropylene emit significant amounts of water when exposed to dry air of air-SF/sub 6/ coronas, and that this is due

By replacing an AC-corona-stressed insulator surface by a metal electrode subjected to superposed AC and DC corona, the authors studied the processes responsible for the DC charging of insulators. A main result is that the charging is critically depe

An attempt is made to correlate the characteristics of the electrical signals due to partial discharges (PDs) with the ageing kinetics of the insulating material subjected to these discharges. The light emitted by a single PD and the corresponding el
