| Abstract | Aging wiring in buildings, transportation systems, consumer products and industrial machinery is among the most significant potential causes of catastrophic failure and maintenance cost in these structures. Smart wire monitoring can therefore have a substantial impact on the overall health monitoring of the system. Well known reflectometry is commonly used for locating faults on wires and cables for a long time. This paper discuss and compares several types of reflectometry methods as time domain reflectometry (TDR), frequency domain reflectometry (FDR), mixed signal reflectometry (MSR), sequence time domain retlectometry (STDR), spread spectrum time domain reflectometry (SSTDR) in terms of their accuracy, convenience, cost, size, and ease of use. Common problems of TDR are the inability to see small reflections and errors in the velocity of propagation are sources of errors. Other sources of errors in TDR are hardware errors – classical measurement error, where some variation in measurements is seen, even without making any changes to the wire under test, its connection. TDR is a most hardest in hardware realization because required highquality generator with precise stability of width and amplitude of pulses. FDR require lowfrequency generator with sinusoidal waveform, but require large memory area to store data from measuring process. All existing FDR methods do not allow eliminating "blind spots" at all. As a result, advantages and limitations of each method are outlined and evaluated for cables. The results in this paper can be extrapolated to other types of wire and cable systems. |
