HZL-300 Full Intelligent Multiple Pulse Cable Fault Location Equipment

1 Product introduction

HZL-300 full intelligent multiple pulse cable fault locator is networking cable fault test platform based on embedded computer platform. It is integrated USB communication technology, touch-screen technology and 3G communication technology and this greatly improved the performance of the instrument in practice and is easy to operate.

This device provides you a specified cable management software to reduce your workload. The whole system meet the requirements of general technical conditions for testing equipment "DL/T849.1 ~ DL/T849.3-2004", Electric Power Industry Standards of the Peoples’ Republic of China.This system is composed of four parts: a host computer system, multiple pulse generator, fault locator and cable router tracer. It  is mainly used for testing all kinds of power cable fault, cable route, cable burial depth and daily management and maintenance of cable data. It can also be used for accurate testing of  railway and airport signal control cable fault and streetlight cable fault. The product has reached international level especially the portability has caught up with world similar products. The core technology of multiple pulse method has completely changed conventional test method. It made the waveform of high resistance fault is easy to read and analysis because multiple pulse generator will transform any complicated high resistance waveform to LV pulse short circuit fault waveform. It greatly improved the accuracy of rough test.

2 Product features

*Adopts embedded industrial computer platform, Window XP system, integrated testing software and installed cable fault testing software and cable data management software which is in the lead in China.  

*Adopts 12.1in large touch screen, can operate by both touch pen or mouse. Bright display is suitable for outdoor use. Lithium battery is convenient on-site testing. Plastic chassis is shock-proof and achieve strong stability.

*Adopts the latest USB communication interface to ensure signal collecting stable. The host can automatically select five kinds of sampling frequency from 6.25MHz to 100MHz, adaptive pulse width can meet the testing requirements of different cable lengths to reduce the rough measurement error and improve test accuracy.

*Automatically distinguish different testing method and locating the fault point Automatically read and display the fault distance. It can be displayed in 3 different areas in the screen and will randomly display 10 low-voltage pulse waveform. It can works automatically or by manual operation to achieve dual-positioning fault. Double vernier can be accurate to 0.15m.

*Unique design of multiple pulse generator. You can finish 3 different testing methods and no need to re-connect wires. One discharge can get 10 low-voltage short-circuit pulse waveform. It can greatly reduce oscillatory interference. Multiple pulse generator is small in size and its weight is only 5kg.

*The host can equip with WIFI receiver and 3G software to get remote on-site test help and suggestions from our experts. Technicians can help on-site testing through android testing software at any time and anywhere.

*The device stores lots of waveform and wiring layouts which is convenient to your compare in site test and study. It can automatically generate test report and print. Cable management system can help you much for cable daily maintenance and cable fault precise locating.

*Precise locator can directly display the distance from tester to fault point. We use squelch technology which is another innovation of domestic similar products. It helps you in locating fault precisely and quickly and also helps your reduce damage and loss arising from power off.

*There are 3 types HV discharge for your choose.Using brand-new 28kg Integral High Voltage Surge Generator replaces 65kg testing transformer and operating box with advantages of wide use, light in weight, this device is in domestic leading level.
