A Line Fault Analysis Algorithm Based on the TDR Test Algorithm

Abstract:

The use of TDR for a single test to analyze the state of communication lines is not accurate to fault location, It also can cause the confusion of fault type and other drawbacks. This paper proposes a analysis algorithm. It can comprehensive analysis TDR test circuit fault pattern and low-frequency circuit parameters of tested line, then it determines the type and position of faults. During a time period, It tests the circuit impedance with 5-element DC model, records the values of line impedance at different times. Combining Curves of the line impedance and TDR waveforms, It accurately determines fault type of the line through the TDR test and Position of fault. By the trying It can increase the accuracy of judging failure , reduce time of repairing.
