摘要： A method for detecting a fault, e.g. a short circuit, break or leakage in an electric cable or conductor, whereby two conductor pairs (1,2 and 4,5), one of which comprises the faulty conductor (1), are connected in such a way as to form a double loop (1,5 and 2,4), a voltage pulse being applied to the intact loop (2,4) to locate the fault (X). Depending on the nature of the defect, the pulse voltage is adjusted to a level sufficient to produce a malfunction, e.g. sparking, in the defective loop (1,5), whereupon the ratio of the currents produced at the ends of this loop is measured and the proportion (U.sub.1 /U.sub.2) is translated into a distance of the fault from the detector.

摘要： A system for locating faults in an electric cable including a flyback transformer or inductor and control circuitry therefor for developing an arc through a high resistance short circuit between two conductors or one conductor and ground. The control circuitry limits the current flow in the arc to avoid burning or welding of the conductors but maintains the current so that the high resistance short appears temporarily as a low resistance short which can be detected. A low level DC bias current stabilizes the system, particularly in the presence of large line capacitance when the distance between the apparatus and the cable fault is large. The circuitry includes an audible tone generator which can be sensed by induction with known inductive pickup equipment. The circuit also allows use of a time domain reflectometer to determine the location of high resistance shorts from a remote location on the cable to which connections can be made.

摘要： A fault locating apparatus for locating high resistance leaks in telephone subscriber lines comprising circuitry for initially applying a low voltage to the line to ensure that the insulation and conductors are dry at the fault zone. When the drying is completed as indicated by a zero reading on an ammeter connected in the circuit, further circuitry is actuated to apply a brief high voltage to the line to cause a brief arc discharge at the fault. At this point, two operative options are made possible. The peak current flow during the arc may be read on a second ammeter providing a measure of the distance to the fault and the apparatus is disconnected or the low voltage application may be continued to sustain the arc until a weld is created at the fault between the line conductors. A feature of the apparatus is a timing circuit which controls means for applying a reverse potential to the line thereby extinguishing the arc at the fault while simultaneously inducing a weld between the conductors there. A reversing switch is also provided to reverse the polarities of the voltages as applied to the subscriber line conductors in a subsequent operation should the first attempt at creating a weld have been unsuccessful.
