  • Measurement system for electric disturbances in a high-voltage switchboard plant
    Patent number: 6130540
    Abstract: In a measurement system for electric disturbances in a metalen-capsulated high-voltage switchgear having at least one measurement probe for each phase for decoupling of electromagnetic interference signals, both the interference signals and the useful voltage are scanned by the same measurement probe in each phase, and both are made accessible, separately from one another, at a filter arrangement.

  • Measuring system for enclosed high-voltage switchgear
    Patent number: 5903157
    Abstract: In a measuring system for an enclosed high-voltage switchgear having at least two poles, each of which is phase segregated, and with sensors for dielectric noise and a detector device connected to them for outputting a signal in the event of an noise, a time comparator is provided that blocks the output of a signal if the time difference between two noise signals from sensors of different phases is less than a certain interval of time, in particular an adjustable interval.
