icon02.png Outline
  • TDR(Time Domain Reflectometer)
    - As the same principle of radar, the cable is pulsed to check the distance and features of a particular point.
    - Echo wave: Pulse echo waves are formed and returned from the position where the impedance changes.
    - Mark the distance by the time the echo waves return.
    2L (Running Distance) = V (Speed) x 2T (Runtime) L = V/2 x T
    * V/2 (VOP-Velocity of Propagation : Pulse propagation rate, cable characteristics)
    - It allows you to determine the location based on the shape of the waveform (e.g. Short / Open / Contact / Fault Point)

  • Low-resistance failure points, length of line, open circuit, short circuit etc. of power cables (shown directly on screen to easily identify line)
    Excellent performance, including selection of various pulses, intermittent fault-point detection modes, long-range distance measurements, and clear waveform displays.
