Abstract (en)

[origin: WO03052892A1] Disclosed is an overvoltage protection device comprising a first electrode (1), a second electrode (2), a spark gap (3) through which air flows and which operates between the two electrodes (1, 2), and a housing (4) accommodating the electrodes (1, 2). An electric arc (5) is generated between the two electrodes (1, 2) when said spark gap (3) is ignited. The inventive overvoltage protection device has a particularly high network follow current quenching capability while being easy to build due to an impedance (6) which is connected in parallel to the spark gap (3) and an isolating distance (8) which is serially connected to the parallel connection (7) between the spark gap (3) and the impendance (6).
