Diagnose faults with TDR-410
The Sonel TDR-410 reflectometer is designed to locate faults in metallic cables. The product is dedicated to electrical wholesalers and cable retailers, electrical installation companies, maintenance workers in production plants and construction personnel. It meets the expectations of all those who need to find the exact location of the damage and the end of the cable in both power and telecommunications cables.
Product features
Application
TDR-410 time-domain reflectometer is designed to detect where faults in metal wires are. This product is designed for electrical wholesalers and cable dealers, electrical installation companies, maintenance personnel at manufacturing plants and building personnel. This device meets the expectations of all those who have to accurately locate a fault and wire end in either power or telecommunications cables.
Device capabilities
SONEL reflectometer is distinguished for their long operating range of up to 4,000 m, very low margin of error in measurement (in the order of 1%) and the ability to adjust both the velocity of propagation and the impedance of the cable which is under investigation.
