Abstract

In an overvoltage arrester composed of two electrodes each presenting a side wall and an end wall transverse to the side wall and whose perimeter is bordered by the side wall, the electrodes being spaced apart to define a spark gap and with their end walls facing one another, and an insulating member interposed between the end walls of the two electrodes, the insulating member is dimensioned to protrude laterally beyond the perimeter of the end face of at least one electrode for causing the initiation of an arc to generate a sliding arc discharge following a curved path around the laterally protruding part of the insulating member.
