Abstract
An arrangement for reducing voltages appearing in turbosets, wherein in addition to a grounding brush (7) on the drive end (DE), another (18) grounding brush is provided on the nondrive end (NDE) and is connected to ground (5) by an RC element (19,20). In this way, when grounding brush (7) on the drive end malfunctions, static charges and alternating frequency currents are reliably discharged. The currents flowing on the nondrive end and the voltages appearing between grounding brush (18) and ground (5) further allow reliable statements to be made about the operational capability and operational safety of the shaft grounding.
