Reflectometer Method:

  • Separate fault location amplifier supplies the high speed digitizer with the received RF-PD-signal
  • Signals are converted with a digital dynamic of 10 or optional 12 Bit and a sampling rate of 100 Ms/s
  • Time delay between the direct measured signal and the first subsequent reflected impulse echo is evaluated in the fault localization unit
  • Impulse echo evaluation for the complete corresponding PD-impulse-reflectograms
  • Localization of multiple faults is possible
  • PD-faults are extracted, evaluated and mapped automatically
  • Reflectometer functionality is easy accessible from the same common LDS-6 software platform

Enhancement of the location sensitivity:

  • Continuous pulse averaging
  • FFT feature assists the user finding harmonic radio interference's; digital filters can be adjusted
  • Transmission-loss-adjustment is automatically executed for all located PD-pulses
