Description

DTDR-100 Digital Time Domain Reflector
DTDR-100 is a 400 MHz high end TDR with 100 km range, which is designed to measure cable total length, fault distance for low resistance or conductor broken cable faults. Together with HVIG-32 HV Impulse Generator, MIMCU-32 MIM Coupling Unit, DTDR-100 can do HV pre-location for high resistance cable faults. DTDR-100 is an easy operation device used for distance locating. It’s easy to operate, support both touch screen/button operation and with friendly interface. DTDR-100 adopts the unique menu operation mode, can use touch screen operation, can also use the mechanical keys, the operation is more flexible, clear, and friendly.

HVIG-32 HV Impulse Generator
  • Integrated design with small size and light.
  • Strong energy, 4 μF capacitor.
  • UK Pelican safety case, professional & portable.
  • Built in energy-storage capacitor without HV leak and safe operation.
  • HV directly connect with the faulty cable, easy wiring and safe operation.
  • Built-in high-power quick charging and short discharge period.
  • Multiple safety protection supports Zero position start and release HV power energy after power off.
  • Multiple working methods of single, period and DC testing adjustable voltage with LED indication.
MIMCU-32 MIM Coupling Unit
MIMCU-32 is designed to match with HVIG-32 HV Impulse Generator and DTDR-100 Digital TDR, to do HV pre-location for power cable high resistance faults, including leaking fault, flash fault, low resistance fault and conductor broken fault. MIMCU-32 is used to provide multi-impulse signal coupling path for DTDR-100 Digital TDR. It adopts the latest multiple impulse method to simple the judgment of the cable fault waveform. MIMCU-32 can transfer the complex voltage surging breakdown waveform into the easy distinguished fault waveform. And the requirement to the technical personnel can be largely reduced.
