2. TIME-BASED – determining the distance to the fault location. It is done by measuring the difference between the acoustic and electromagnetic pulses emitted by the cable at the moment of discharge through the fault location.

3. FAULT DEPTH – determining the depth of the fault location.

It is designed for:

– Determination of the route location and the depth of the cable;

– Search and precise identification of location of faults in insulation of cable lines.

Complete set of IFL-1210:

The kit for route searching is one of the best and most modern cable avoidance tools in the country.

The device is designed for accurate determining the location and depth of underground communications (power and signal cables, pipelines), faultfinding in cable lines. Besides, it enables to conduct a survey of the terrain before excavation and prevent damage to utilities promptly and reliably.

Measurement methods:

– pulse mode;

– pulse-arc mode (Arc Reflection);

– voltage wave method. Current wave method.

Main functions:

– measuring cable lengths;

– measuring distances to inhomogeneities of the impedance or damages using the pulse method;
