System application

Quick and accurately detect all the faults of 35KV,10KV,6KV,3KV and 1KV power cable and various multi-core control signal cable.Detect low resistance,open-circuit defect for other above two-core(include coaxial) cable.Display the tap position in the cable.Calibrate the length of cable.Probe the cable underground direction and depth.

System composition

1.DGS-AV series cable fault tester: coarse detection for cable fault and is the core of the whole set of equipment

2.DGD-SD series cable fault locator: to fix the accurate position of the cable fault

3.DGL series cable path finder: to detect the direction and depth of embedded cable.

4.High voltage equipment:FQ discharge sampler,GZF Frequency HV test equipment,CC series impulse Engery-saving Capacitor and CXZ whole set of detector Wires.They are the assistant devicefoe the coarse detection of cable fault tester and accurate position of fault point for orientation detector

System functions

1. Multi-function: can detect the distance,speed,resistance,path and depth.

2.Long distance detection: can detect the 100km cable and more.

3.High accuracy: the absolute tolerance of final accurate detection is 0.1m.

4.Powerful capability: auto-sample and no discharge wave can be missed.Auto-judge the discharge of fault point,the process is reminded by english.Auto-judge the type of fault and display detection method.

5.Measurement method: impulse,flash voltage,flash current ,direct-flash voltage,direct-flash current,flash and direct flash.

Mesuring range: Smax≤40km  no blind area.

Test Error:±0.1m
