The underground cable fault locator is a portable detection device consisting of a transmitter, receiver, and a full set of accessories. It is suitable for a variety of scenarios, including communication cable construction, power cable maintenance, building pipeline location, and electric heating line inspection.
Efficient and Accurate Location
- The fault finder utilizes digital signal modulation technology. The transmitter sends a high-frequency AC voltage signal to the target cable (or metal pipe), generating a stable alternating electric field around it. The receiver senses the changes in the electric field, amplifies the weak signal, decodes it, and intuitively displays it, helping users quickly locate the specific location, direction, and fault point of the cable/pipeline.
- Two core detection modes, unipolar and bipolar, cover the full range of scenarios, from simple line tracing to complex fault diagnosis. The unipolar mode is suitable for tracing lines in de-energized conditions, locating breakpoints, and short circuits. The bipolar mode supports live line detection, finding fuses, and identifying circuit faults, with a maximum detection depth of 0.5 meters.
- The underground fault finder transmitter features a built-in AC/DC voltmeter that can directly measure line voltages in the range of 12-400V (with an accuracy of ±2.5%). It also displays the AC/DC type and a high-voltage lightning symbol to prevent accidental contact with live lines.
Adaptable to Complex Environments
- The receiver has a built-in speaker that emits a tone that changes with signal strength, allowing you to determine the location without having to stare at the screen. A "silent mode" (available on both the transmitter and receiver) can be enabled in noisy environments, allowing for quiet operation in sensitive locations like hospitals.
- The underground fault locator features a backlit LCD display for clear visibility in dimly lit environments. It displays transmitter power, code, battery charge on both sides, and signal strength (both as a bar graph and as a digital indicator).
- The underground cable fault finder supports automatic/manual sensitivity adjustment. In manual mode, the fault point can be accurately located, while in automatic mode, it is suitable for fast scanning. It also has an automatic frequency scanning function to reduce environmental interference and ensure accurate signal capture.
Applications
The cable fault locator is suitable for multiple scenarios: troubleshooting high and low voltage cable faults in the power industry, testing communication cables in the communications industry, troubleshooting production cables in industrial enterprises, locating indoor cable problems in the civil construction field, and can also be used for cable fault detection in special environments such as ships, rail transit, mines and oil fields.

Q1: How to Use a Cable Fault Locator?
A1: To use a cable fault locator, connect the instrument to the faulty cable, select a test mode (such as low-voltage pulse or high-voltage flashover), transmit a signal, analyze the reflected waveform, determine the distance to the fault, and then precisely locate the fault along the cable. After repair, retest to confirm the location.
Q2: How Does a Cable Fault Locator Work?
A2: Cable fault locators typically use technologies such as time domain reflectometry (TDR), bridge technology, and acoustic-magnetic synchronization. They are portable, easy to use, and offer high locating accuracy. They are widely used in cable maintenance and emergency repair in industries such as power, communications, railways, and petrochemicals, significantly improving troubleshooting efficiency and reducing power outage time and repair costs.
Q3: What Factors Affect the Test Accuracy of a Cable Fault Locator?
A3: The test accuracy of a cable fault locator is affected by a variety of factors, including cable length, type, installation environment, and connector quality; the instrument's sampling rate, pulse width, signal processing capabilities, operator experience, external electromagnetic interference, grounding conditions, and fault type (such as low-resistance, high-resistance, flashover, or broken wire). These factors together determine the accuracy and reliability of fault location.
Tips: What Parameters Should I Consider When Purchasing a Cable Fault Locator?
When choosing a cable fault locator, consider its test accuracy to ensure accurate fault location. The measurement range should meet the required network cable length. The interface should be compatible with a variety of network cables. It should include practical functions such as TDR. The user interface should be simple and easy to use. Also consider the device's portability, durability, and the availability of additional features such as high-voltage detection and audio recognition.
