Time Domain Reflectometer – Overview

TDR-410 time-domain reflectometers are designed to detect the location of faults in metal wires. These products are designed for electrical wholesalers, cable dealers, electrical installation companies, maintenance personnel at manufacturing plants and building personnel.

SONEL reflectometers are known for their long range, up to 4,000 m for the TDR-410, very low margin of 1% error in measurement, and the ability to adjust both the velocity of propagation and the impedance of the cable which is under investigation. Two cursors indicate the distance to 2 faults and the distance between them.

Cable fault location Includes:

• Locate damaged power cables
• Fault location for copper telecom cables
• Coaxial cable fault location
• Fault location for wiring infrastructure
• Detection of breaks, short circuits and damage
• Graphic depiction of damage to cable
• Automatic indication of the distance to fault
