Method and apparatus for locations of the cable sleeves and cable faults in the case of laid cables

摘要

A method for the locations of the cable sleeves and cable faults, such as connecting sleeves, branching sleeves and the cable jacket errors of cables laid in the ground by means of a coupled to the cable - audio frequency generator and by means of a tracking of a cable route with a on the audio frequency - generator tuned receiver with at least two orthogonal associated antenna coils, which have a horizontal and vertical directional characteristic, as well as by the orientation of a maximum signal by an antenna coil and a minimum signal by the other antenna coil is produced, which are fed to an evaluation device, characterized in that, in approximately equal intervals a cable route the measured values of the antenna coils is measured and are fed to a measurement value storage, as well as by means of a computing unit both series of measurements of the measured values on a display unit in relation to the track curve is shown by way of the arithmetic unit the measured values of each measuring point to one another and the ratio of the series of measurements as a degree of the inhomogeneity of the magnetic field with respect to each measuring point in the form of an identifier (lines thickening, color code, pattern) of the series of measurements is shown.
