Monitoring device for monitoring residual voltage, has protection device to perform safety-promoting measure to avoid contact of voltage-carrying part by person when output signal indicates that voltage amount exceeds threshold value

摘要

The monitoring device (40) has a voltage detecting device (61) for determining the amount of voltage between a conductor and a reference potential guiding conductor and for generating a measurement signal in dependence upon the voltage amount. A protection device is provided to perform a safety-promoting measure to avoid a contact of a voltage-carrying part by a person when an output signal indicates that the voltage amount exceeds the allowable threshold value. An independent claim is included for a method for monitoring residual voltage.
