Product Details

1. Overview

Cable Tracer and Fault Locator It is the latest-generation, dedicated cable fault locator meticulously designed and developed by our company specifically to address the characteristics of “power cable faults.” It primarily addresses short circuits, open circuits, and ground‑fault issues in directly buried underground cables. Its key features include high receiving sensitivity, strong anti‑interference capability, stable signals, clear path tracing, and precise pinpointing! The instrument features a built-in power supply, a compact footprint, and lightweight design for easy portability, enabling single‑operator use. It is particularly well suited for field applications, as it is unaffected by cable‑laying conditions such as paved surfaces, conduit installation, or branching points, thereby greatly enhancing user convenience, boosting operational efficiency, and reducing labor intensity.

This instrument operates on the principle of electromagnetic induction and requires no step-up transformer, thereby ensuring the safety of cables, electrical equipment, and testing personnel. Simultaneous testing of the cable route, fault location, and burial depth is also performed. Unlike previous methods that relied on applying high voltage to induce discharge at the fault location, this approach—based on sound‑level analysis for fault localization—transforms what was once a tedious and complex task into a remarkably simple and straightforward process. This instrument employs a quartz crystal oscillator and medium- to large-scale integrated circuits. Its key features include high receiving sensitivity, minimal static drift, strong anti‑interference capability, stable operation, and high accuracy. Moreover, powered by a compact nickel‑cadmium rechargeable battery, it boasts a small footprint, light weight, low power consumption, and portability. Especially suitable for field testing. 。

In addition, this instrument is particularly well suited for locating ground faults and open‑circuit faults in single‑core cables—issues that cannot be resolved by the impulse flashover method—providing accurate and rapid fault location with errors measured in centimeters.
