HD-A20 Cable Fault Locator

 

Introduction

HD-A20 CABLE FAULT LOCATOR integrated industrial embedded computer platform, Network Communications Service and USB communication system to improve the utilization of the device. Specially, the device has loaded a system for underground buried cable data save and meet the national standard. The device consists 3 parts:  main system, fault locator and cable line tester. It is used for cable fault location, cable line and depth test and daily maintenance of cable data. It can also be used for signal cable fault location for railway station and airport.

Features

 We are the first company in China who use industrial embedded computer platform system into cable fault locator. Lithium-power supply affords the convenience of field tests.

◆ We are the first company in China who use 12.1 inch touch-screen and windows XP system.

◆ The device adopt USB communication interface. The host can select 5 sampling frequency automatically between 6.25 MHz to 100MHz for the cable of different length.

◆ The device can search the fault point and display the distance automatically, the movement of double cursor can be accurate to 0.15m. The waveform can be compressing or expanding freely. At the same time the system will display two waveforms randomly which is close to standard waveform for your reference.

◆ The device saves total 40G waveforms and on-site wiring diagrams for your reference.

◆ We developed smart modular sampler to replace the on-site wiring, the sampling is totally separated with high-voltage to ensure the safety of the operator.

We developed HD-G35 high frequency high voltage power supply (8.9Kg) to replace the testing transformer and operation box (65Kg).

 

Main parameters：

1）Digital display distance：Max. 500m，Min. 0.1m

2）The sketch test error is less than 10%，location error is zero.

3）Electromagnetic channel gain is more than 110dB (300,000 times).

4）The sensitivity of electromagnetic channel receiver is less than <5μV.

5） Sounding channel audio amplifier gain is less than 120dB (When the ratio of signal-to-noise is 4:1, the audio signal will be amplified 1 million times.)

6）50Hz power frequency restrain degree is more than 40dB (100 times).

7）Scoustoelectric synchro-display and monitor：In actual location operation, digital screen will count repeatedly under the influence of the electromagnetic wave and show the distance of the fault, the maximum distance reading is 500m. Meanwhile, the hi-resistance earphone will monitor the seismic wave produced by the spark arising from the fault-spot been punctured to get rid of the interference of the clutter wave.

8）If you change the sound wave probe to 15KHz electric sensing probe, this device can also be used for testing the cable path and the buried depth precisely.

9）Power source：6V free from maintenance battery of 1.2AH.

10）Power loss： <120mA     (0.7W)

11）Operational environment： humidity 80% , temperature  -10℃—50℃
