pruefgeraet zum ermitteln der durschlagsfestigkeit von isoliermedien

摘要

Test set for the determination of the breakdown voltage instantaneous value of insulating media, especially for monitoring the insulation gas quality of insulation gas-filled switching installations, consisting of a high voltage generator in the form of a press-knob operated piezo element and a breakdown voltage indicator in the form of a glow lamp. The outputs of the piezo element can be applied to a spark-gap in the insulation gas space of the switching installation. The press-knob actuated piezo element generates a high voltage pulse which, in the case of insufficient insulation gas quality, generates a strike-over on the spark gap and leads to a display of the glow lamp.
