ABSTRACT:
A method for detecting ground faults between a community antenna television (CATV) coaxial cable and an appliance coupled to the CATV coaxial cable for receiving CATV broadcasts is provided. A potential difference between a shield of the coaxial cable and a chassis of the appliance is determined. A fault indicator is provided, if the potential difference exceeds a predetermined threshold voltage. An apparatus for detecting ground faults between an appliance and a CATV coaxial cable is also provided. The apparatus includes a comparator. A first input of the comparator is coupled to a chassis of the appliance. A second input of the comparator is coupled to a shield of the coaxial cable. The comparator indicates a fault condition if a potential difference between the first and second inputs exceeds a predetermined threshold.
