Electric device comprising at least one low-pressure mercury vapor discharge tube

摘要

An electric device comprising at least one low-pressure mercury vapor discharge tube intended to be connected to an AC voltage source at a frequency of 50 to 60 Hz. The discharge tube is of a type which produces a comparatively large current distortion and has a proportionally low required reignition voltage. The electric device produces relatively small electric losses. The discharge tube remains operative even for small deviations of the nominal AC supply voltage.
