Abstract
System and method for locating a fault on a line comprises a sampler that samples a pulse from the fault, the sampling being carried out at a predetermined sampling rate. A differentiator produces a differential or derivative of the pulse, and an analyzer obtains timing information from the derivative, from which it is possible to locate the fault knowing the total length of the line and the wave propagation rate.
Claims23
System for locating a fault on a line, the line having a first end and a second end and a first direction being from said first end to said second end, the system comprising:
- a first sampler configured to sample a pulse, the pulse emanating from a fault, the pulse being in a second direction opposite said first direction, the sampling being at a predetermined sampling rate;
- a differentiator configured to produce a differential of said sampled pulse;
- an analyzer configured to analyze said differential to obtain a timing, therefrom to determine a location of said fault.
Method for locating a fault on a line, the line having a first end and a second end and a first direction being from said first end to said second end, the method comprising:
- sampling a pulse, in a second direction opposite said first direction, the pulse issuing from said fault, the sampling being at a predetermined sampling rate;
- obtaining a differential of said sampled pulse;
- analyzing said differential to obtain a timing, therefrom to determine a location of said fault.
