Product Description
■ Product Overview
The cable fault locator employs time-domain analysis to detect low‑impedance, short‑circuit, open‑circuit, high‑impedance leakage, and high‑impedance flashover faults in power cables of various voltage levels, as well as in communication coaxial cables, local‑loop cables, control cables, mining cables, and submarine cables.
■ Product Features
It features multiple testing methods, such as the low-voltage pulse method, the impulse high-voltage current sampling method, and the DC high-voltage flashover method, among others.
The instrument is powered by a high-energy polymer rechargeable battery, and the sampling board interface is USB The model employs a microcomputer‑based power supply and incorporates advanced current‑sampling technology, ensuring complete isolation between the operator and the test instrument from high voltage. This design delivers strong anti‑interference performance while safeguarding both test reliability and operator safety.
The front‑end sampling and measurement unit employs advanced signal‑processing technology, features a fully Chinese‑localized display, and presents test waveforms with clear, easily distinguishable characteristics. , This makes cable fault analysis easier to master.
. Adopt Wince Operating system software with a more user-friendly design and simple operation. A domestic first. , It is a fully automatic cable fault analyzer that addresses the challenge faced by field technicians who often struggle to interpret fault waveforms. This intelligent testing instrument significantly enhances operational efficiency and resolves long-standing issues for customers.
Dual‑trace simultaneous on‑screen comparison and waveform‑superposition data‑processing technology facilitate comparative waveform analysis. This functionality is equivalent to the on‑screen comparison and superposition feature of a multi‑pulse cable fault locator.
This instrument features selectable positive and negative pulse polarity and automatic waveform analysis of fault locations.
