Editing Time-domain reflectometer (section)

=== In aviation wiring maintenance ===
Time domain reflectometry, specifically [[spread-spectrum time-domain reflectometry]] is used on aviation wiring for both preventive maintenance and fault location.<ref>Smith, P., [[Cynthia Furse|C. Furse]], and J. Gunther, 2005. "Analysis of spread spectrum time domain [http://livewiretest.com/analysis-of-spread-spectrum-time-domain-reflectometry-for-wire-fault-location/ reflectometry for wire fault location] {{webarchive|url=https://web.archive.org/web/20101231231446/http://livewiretest.com/analysis-of-spread-spectrum-time-domain-reflectometry-for-wire-fault-location/ |date=2010-12-31 }}". IEEE Sensors Journal 5:1469–1478.</ref> Spread spectrum time domain reflectometry has the advantage of precisely locating the fault location within thousands of miles of aviation wiring. Additionally, this technology is worth considering for real time aviation monitoring, as  spread spectrum reflectometry can be employed on live wires.

This method has been shown to be useful to locating intermittent electrical faults.<ref>[[Cynthia Furse|Furse, Cynthia]], Smith, P., Safavi, Mehdi, and M. Lo, Chet.

Multi carrier time domain reflectometry (MCTDR) has also been identified as a promising method for embedded EWIS diagnosis or troubleshooting tools. Based on the injection of a multicarrier signal (respecting EMC and harmless for the wires), this smart technology provides information for the detection, localization and characterization of electrical defects (or mechanical defects having electrical consequences) in the wiring systems.
Hard fault (short, open circuit) or intermittent defects can be detected very quickly increasing the reliability of wiring systems and improving their maintenance.<ref>G.Millet, S.Bruillot, D.Dejardin, N.Imbert, F.Auzanneau, L.Incarbone, M.Olivas, L.Vincent, A.Cremzi, S.Poignant, 2014.[https://www.researchgate.net/publication/260075393_Aircraft_Electrical_Wiring_Monitoring_System "Aircraft Electrical Wiring Monitoring System"]</ref>
