Method for locating a cable fault in a test cable and corresponding device
The method involves determining a phase shift at a test cable end, another phase shift at another test cable end and a propagation constant of the test cable. The electric system or the test cable is stimulated, so that the electric vibration is impressed on the electric system or the test cable. Th...

| Zusammenfassung: | The method involves determining a phase shift at a test cable end, another phase shift at another test cable end and a propagation constant of the test cable. The electric system or the test cable is stimulated, so that the electric vibration is impressed on the electric system or the test cable. The impressed vibrations are measured, so that a frequency spectrum or a time signal is determined. The frequency analysis of the frequency spectrum is executed, and the total phase shifting and an electric length of the test cable are determined. An independent claim is included for a device for locating a cable fault in a test cable by a test device of an electric system. |
