21st Century Dual Mode TDR for Testing and Monitoring Energized and Unenergized Cables

The Arc Chaser Dual Mode TDR is capable of finding faults (Opens, Shorts, Arc Faults) on fully energized cables up to 600 Volts. Arc Chaser can monitor live cables for intermittent conditions, capturing these “events” and reporting where and when they occur. Using advanced Spread Spectrum Time Domain Reflectometry (SSTDR), Arc Chaser is capable of accuracy to fault of better than 1%.

  Q. What is the difference between SSTDR and TDR?
  A. Please see the SSTDR vs. TDR difference here: http://t3innovation.com/technologies
  Q. What is the difference between the red and black banana jacks?
  A. The red banana jack is the SSTDR output. The black banana jack is the SSTDR return path. If testing a single wire but using a chassis or conduit as a return path, connect the red lead to the wire then the black lead to the chassis/conduit.
  Q. What is VOP?
  A. VOP (Velocity of Propagation) is a measurement of how fast a signal travels over time.
  Q. How do I determine a cable’s VOP?
  A. You can discover the VOP of a cable by taking a known length of cable and select “Discover VOP” in the Fault Location Test Setup screen (see pg. 17 & 18 of the instruction manual for details).
  Q. Why/When should I use the leader cable?
  A. The leader cable should be used when not testing coaxial cables. The leader cable improves accuracy by continuing the Arc Chasers internal impedance while distancing the launch pulse from the connection to the cable under test. The Arc Chaser will calibrate the length of the leader when “Leader” is selected in Test Setup.
  Q. Why do I get a 0ft reading or Error when I connect to a cable?
  A. The test lead crocodile clips are separated too much, causing an impedance mismatch.
  A. The Crocodile clips are not making connection with the leader cable. Make sure the leader cable is inserted into the crocodile clips all of the way.
  A. The cable is connected to a terminated device on the other end that is absorbing the SSTDR reflection (like a 75Ohm terminator or resistor).
  Q. What’s the difference between Fault Location and Live IFD?
  A. The Fault Location (FL) test performs a single measurement to determine the distance to a fault. This test is also useful in determining the cable frequency and discovering VOP (see pgs. 16-19 of the instruction manual for details)
  A. The Live IFD mode monitors the cable under test for intermittent faults. The Live IFD test will provide a distance to two fault locations at a time, fault type, and the fault count. (see pgs. 21-23 of the instruction manual for details)
  Q. What do the different frequencies do? How do I pick the right frequency?
  A. The frequencies determine the length of cable to be tested. The Fault Location test will automatically discover and display the cable test frequency to be used for Live IFD testing.
  Q. Why does the Arc Chaser use Frequency vs. Pulse Width?
  A. Selecting a specific frequency limits the amount of power on the line for a given range. This allows our TDR system to perform in noisy environments, so the cable can be monitored while power is on the cable.
  Q. When connecting to an airframe or vehicle chassis, how do I determine my VOP?
  A. This will vary depending on the type of wire being tested and the size of the airframe or vehicle. You can measure between connection points (like an outlet/break out box) to a console), connect the Arc Chaser to one end of the wire and the chassis, select Fault Location, Discover VOP, then enter the measured length. You can save this VOP for future use. Typically, an airframe and aircraft cable will have a VOP of +/- 58.
  Q. What is the maximum voltage the Arc Chaser can connect to?
  A. The Arc Chaser is CATII rated and has internal protection up to 600V AC and DC. To avoid personal injury, do not exceed CATII voltages. (See instruction manual for specifications and warnings).
  Q. If I connect to a cable with voltage, what range of Hz will the Arc Chaser work with?
  A. The Arc Chaser will work on voltage frequencies from 5Hz to 1000Hz.
  Q. What are the Arc Chaser reporting formats?
  A. The Arc Chaser can save test results as a PDF in Fault Location mode and also in Live IFD as PDF or CSV (excel).
