Cable Fault Locator TDR RI-303BM “SWIFT”
Handheld with Bluetooth module

The optimal solution for quick troubleshooting in cable networks is an extremely easy-to-use and inexpensive TDR cable fault locator with built-in cable voltage protection, non-volatile memory and a Bluetooth module. High accuracy characteristics allow it to be effectively used both in near and far zones.

Cable Fault Locator TDR RI-303BM

Small dimensions and weight make TDR RI-303BM especially convenient for work in confined conditions of cable wells.

Overview

Purpose

Portable reflectometer-tester RI-303BM is designed for the following types of measurements on balanced and unbalanced cables:

  • measurement of cable lengths;
  • measurement of distances to impedance irregularities or faults;
  • breaks of one or more cores;
  • short circuits and low resistance defects (less than 1 kΩ);
  • defective solders and couplings;
  • faulty amplifiers;
  • presence and place of branches installation;
  • areas with high humidity;
  • measuring the Propagation Factor of the line at a known length;
  • determination of the nature of fault;

Application area

The RI-303BM compact reflectometer is used for control during the laying and operation of the following types of cable lines:

  • power cables;
  • copper-core communication cables;
  • signaling and control cables;
  • overhead cable lines;
  • computer networks;
  • television and radio frequency cable lines.
  • to determine the length of the cable during its production, storage and trade.

Power cables of all types:

  • Power cables with impregnated paper insulation in lead sheath
  • or aluminum sheath
  • Power cables with rubber insulation
  • Power cables with PVC insulation
  • Power cables with polyethylene insulation

in all electrical networks where the power cable is used:

  • General-purpose electrical networks;
  • Autonomous power supply networks;
  • Repair and maintenance of water transport;
  • Technological networks;
  • Metallurgical industry;
  • Mining industry;
  • Railways;
  • etc.

Heating cables of the main types:

  • resistive type
  • self-regulating type
