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 diversion strategies, where the conductor to be protected is made as unattractive as possible compared to(More)
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, subjected to fast-rise (1.2 /spl mu/s) and slow-rise (150 /spl mu/s) positive and negative impulse voltages,(More)
