ABSTRACT:
An electrical system fault detector for connection across the source terminals of an electrical system includes circuitry responsive to the relative potentials and current flows between the terminals and a selected point in the electrical system to provide a digital indication of acceptable continuity when current can flow between the selected point and one of the terminals and the potentials thereat are approximately equal. A lack of an indication of acceptable continuity indicates a fault such as an open circuit oran excessive impedance between the selected point and the terminal to which it is connected. An incongruous indication would further indicate a fault such as an incorrect connection or a short circuit. Further circuitry produces and is responsive to an oscillating signal subject to line impedances to distinguish between an open circuit and an excessive impedance.
