◇TDR, ARM, ICM and Decay methods for power cable lines
◇Large bright color 10.4″ TFT display 640 x 480 pixels
◇Wide range: from 1 m to 128 km
◇Powerful probe pulse: up to 86 V amplitude
◇High resolution: 0.12 m
◇Memory for 300 waveforms and USB data exchange

Applications on power cables include :

  • Cable length measurement and cable integrity tests
  • Distance measurement to low resistance fault, using TDR method
  • Distance measurement to high-resistance fault, using Arc Reflection Method (ARM) in conjunction with high-voltage pulse generator (HVPG)
  • Distance measurement to high-resistance fault, using Impulse Current Method (ICM) or Decay Method in conjunction with high-voltage pulse generator (HVPG)
  • Measurement of the velocity factor of the line at a known length
