Cable fault locator TDR-TA3.3TM
Cable fault locator TDR-TA3.3TM
TTDR-TA3.3TM is portable time domain reflectometer with automatic protection of incoming voltage in cable lines. It was designed for the following types of measurements on balanced and unbalanced cables.
Key features
- Cable length measurement.
- Measuring distances to impedance irregularities or faults.
- Measurement of the velocity factor of the cable.
- Determination of the fault nature.
Features
- Automatic protection from cable voltage;
- 100 measurements memory;
- 6 000 mA*H Li-Ion accumulator;
- Auto calculation and numeric indication of distance to the cable fault;
- 12.5 cm accuracy at whole measured distance;
- Library of most common Velocity Propagations;
Application Area
The optimum solution for rapid troubleshooting of cable networks – extremely easy to operate, compact and cheap TDR tester.
TDR-TA3.3TM – a single-channel cable fault locator, designed to determine the nature and location of the cables faults (open, short, sleeve, cable splice, parallel challenge, Pupin coil).
The small size and weight make the TDR-TA3.3TM especially convenient for working in confined spaces cable wells. High precision characteristics allow to measure near and far zones.
Sphere of application
TDR-TA3.3TM is intended to measure on cables of the following types:
- signal and control cables;
- power cables;
- aerial cable lines;
- computer networks ;
- TV and radio cable lines.
