  • Patent number: 9543756
    Abstract: A pulse generator circuit arrangement for the search for insulation faults in IT networks includes a rectifier circuit for transforming an IT network voltage into a DC intermediate circuit and switching elements having a trigger signal input for switching on and off a DC intermediate circuit voltage. A circuit device downstream of the switching elements generates a pulsed current to be supplied to the IT network. The circuit arrangement includes a control and evaluating logic for determining the insulation resistance of the IT network and also a circuit device for generating the pulsed current, which is formed as a current regulating device and allows a dynamic adjustment of the pulsed current depending on the determined insulation resistance.

  • Publication number: 20130328571
    Abstract: A method and to a device for insulation monitoring in ungrounded electrical direct or alternating current networks includes coupling in a measuring signal between active conductors of the network to be monitored and ground and registration of measured values of the measuring signal. The registered measured value of the measuring signal is determined in the form of a signal quality value which is displayed on a display.
