  • Coupling of communications signals to a power line
    Patent number: 7778514
    Abstract: In one embodiment, a system for coupling a communications signal to a medium-voltage power line includes a surge arrester electrically coupled to a medium-voltage power line and a disconnect device electrically coupled to the surge arrester. The disconnect device is electrically coupled in parallel with a communications device and has a resistance of at least one thousand ohms and a capacitance between one picofarad and twelve picofarads. Furthermore, the disconnect device is electrically coupled to a ground without the use of ferrites.
    Type: Grant

  • Ground fault detector for line-powered telephone network
    Patent number: 5774316
    Abstract: A ground fault detection and line power supply control system protects telecommunication service personnel working on line-powered telephone circuits from ground faults, without requiring that the line power supply be disconnected or shut down prior to a technician working on the line. A ground fault loop sensing current is sourced from an auxiliary DC voltage source that is separate and distinct from the line power supply. This auxiliary DC voltage source is coupled through a ground fault current sense resistor to one side of the powered line, so that detection of a ground fault condition is not dependent upon the supply of current from the potentially hazardous line supply.
