Underground Cable Fault Detector

Darui Electric recommends:

Features

◆ Underground cable fault detector adopts an industrial control embedded computer platform system, full computer XP system operation platform, integrated software testing, and is equipped with cable fault testing software and cable data management learning software.

◆ It adopts a 12.1in large screen touch system, dual control with touch pen and touch mouse, high-brightness display, suitable for outdoor sunlight use, lithium battery power supply, convenient for on-site testing. Engineering plastic chassis, shockproof and moisture-proof to achieve strong stability.

◆ Using a new USB communication interface, the signal acquisition is stable. The host can automatically select five sampling frequencies from low 6.25MHz to high 100MHz, adaptive pulse width, which can meet the testing requirements of cables of different lengths, reduce rough measurement errors, and improve testing accuracy.

◆ The software realizes automatic identification and search of low-voltage pulse and multiple pulse methods, automatic clamping of waveform fault inflection points, automatic reading and display of fault distance by the instrument, three-zone waveform display on the same screen, ten low-voltage pulse waveforms randomly displayed on the same screen for selection, and simultaneously realizes two modes of automatic and manual processing, enabling double clamping operation of the waveform. Dual cursor movement can be accurate to 0.15 meters, improving rough measurement accuracy and reducing waveform errors.

◆ The unique multiple pulse generator design allows three methods to be tested on site without rewiring, and one discharge can obtain ten low-voltage short-circuit pulse waveforms, greatly reducing the interference of large oscillations. The multiple pulse generator is small in size, weighing only 5KG, truly realizing the lightweight of the complete set of equipment.

◆ The host supports built-in WIFI reception function, and the dedicated 3G software can realize expert remote real-time on-site testing technical services at any time. Experts remotely control the user's host, and the business technology is equipped with a mobile phone Android version testing software, providing users with timely and accurate waveform analysis and communication guidance anytime and anywhere, making your work worry-free.

◆ The built-in on-site waveform and on-site physical wiring new 8.4kg HP-G35 high-frequency high-voltage power supply replaces the 65kg test transformer and operation box. The HP-G25 built-in capacitor integrated high-frequency high-voltage power supply high-voltage impact part has a wide application range and is truly comprehensive and lightweight.
