Abstract

The aim of the present work was to study the causes of arcing at the first burning of cleaned but not secondary recrystallized filaments. The lifetime of incandescent lamps is controlled by evaporation of tungsten, creep of the filament under its own weight at the operating temperature and arcing. Since both creep and fracture might lead to arcing, this paper deals with the relations between the properties of the filament and arcing. Potassium bursts can be observed during stationary burning.
