Fully intelligent multi-pulse cable fault comprehensive tester

The system consists of host computer, pulse generator, fault locator and cable routing instrument. It is used to test all kinds of faults of power cable, find out cable routing and cable burying depth, and maintain and manage cable archives. and precise testing of railway airport signal control cables and street lamp cables for faults.

product characteristics

◆ The first domestic industrial embedded computer platform system, industrial-grade use environment, to achieve strong stability. Lithium power supply, convenient field test.

◆ The first in China to adopt 12.1 inch large screen touch system, full computer XP operating platform integrated software, completely bid farewell to the era of cable instrument MCU, and equipped with cable fault testing software and cable data management software.

◆ The software realizes automatic identification and search, automatic display of fault distance, automatic alarm function of false card, waveform display in three areas on the same screen, ten low voltage pulse waveforms displayed randomly on the same screen for you to choose, automatic and manual analysis area, so that the waveform can be double clamped operation, double cursor movement can be accurate to 0.15 meters, improve rough measurement accuracy and reduce waveform error.

◆ Adopt * new USB communication interface, stable acquisition signal, equipped with a notebook computer can achieve dual control dual display, the host can automatically select * low 6.25MHz, * up to 100MHz five sampling frequencies, can meet the test requirements of different length cables, reduce the rough test error.

◆ Three kinds of high voltage discharge parts are available for users to choose from, the first in China * New HNLC-G high frequency high voltage power supply 8.4kg replaces 65kg test transformer and operation box, filling a blank in China.
