| Abstract: | This article introduces two new cable fault detection and location on line methods-sequence time domain reflectometry method（STDR）and spread spectrum time domain reflectometry method（SSTDR）-based on an overview of the cable fault type and the existing methods of cable fault detection and location.And then analyzes the principles of these two approaches,selects a correlation algorithm applicable to both of these two methods so as to improve frequency-domain correlation algorithm for Real-valued sequences.At last,a simulation model in MATLAB is established.These two methods are simulated,validated,and compared.It＇s theoretical guidance for practical application. |
