Definitions
- An arrangement for deriving overvoltages is described. Furthermore, the use of the arrangement in an electronic device or in an electrical network is described.
- An overvoltage arrester serves to limit dangerous or undesirable overvoltages in electrical cables and devices. This can cause overvoltage
- Gas-filled surge arresters also referred to as gas arresters, are surge arresters in which the overvoltage in the gas manifold is dissipated by the automatic ignition of a gas discharge. They work according to the gas-physical principle of arc discharge, whereby after reaching a trap voltage, briefly as
- ignition voltage Operating voltage or referred to as ignition voltage, forming an arc in the gas-tight discharge space within nanoseconds. Due to the high current carrying capacity of the arc, the overvoltage is effectively short-circuited.
