portable intelligent power underground cable fault locator

RDCD-850 Cable Fault Locator, used with high voltage signal generator, is a portable and intelligent power cable fault locator.

Functional features

1. Background noise reduction helps remove unwanted sounds from the test site. As a result, the discharge sound at the fault point becomes easier to hear.

2. An intelligent algorithm calculates the acoustic and magnetic delay value for fixed-point detection. Testers can use the result directly without complicated manual calculation.

3. Moving the sensor activates the automatic mute function. This prevents handling noise from reaching the headset and also helps protect the operator's ears.

4. Cable direction can be checked with the built-in electronic compass. The screen also shows the sensor position and its angle during testing.

5. Sound filter settings are adjustable according to site conditions. Different frequency ranges can be selected when environmental noise affects the test.

6. Automatic gain control responds to the detected magnetic field signal. It adjusts the gain during fixed-point work, so manual adjustment is needed less often.

7. A noise-resistant monitoring headset is included for field use. It helps the operator monitor the detected sound during cable fault location.

8. For outdoor testing, the 800 × 480 color LCD remains easy to read. With brightness up to 800 cd/m², the screen can be viewed clearly in sunlight.

9. Power is supplied by a built-in high-capacity lithium-ion battery. Charging is available through the USB interface.

10. Its compact size and low weight make the equipment easy to carry. This is useful when technicians need to move between different cable testing points.

How Is the Acoustic Magnetic Fault Locator Used in the Field?

During underground cable testing, technicians first use the magnetic signal to confirm the cable route and locate the general fault area. The acoustic channel is then used to narrow down the fault position. When background noise is high, the operator can change the filter setting or use the noise reduction function.

For final fixed-point detection, the intelligent algorithm provides the acoustic and magnetic delay value. This helps technicians identify the fault point without relying only on manual judgment.

Why Does Acoustic and Magnetic Detection Matter?

Underground cable faults can produce both electromagnetic and acoustic signals. The magnetic channel helps technicians follow the cable and identify the testing area. After the fault area is narrowed down, the acoustic channel can help find the exact fault point.

For sites with strong interference, adjustable sound filters and noise reduction modes give operators more control over the signal they monitor.

FAQs

Q1: How does an acoustic magnetic cable fault locator improve underground cable fault detection accuracy?

A: An acoustic magnetic cable fault locator combines sound and magnetic signal detection technologies to identify underground cable fault points more accurately. The system uses both acoustic and magnetic channels with a signal gain of more than 80 dB, helping technicians detect weak fault signals in complex environments.

Q2: What is the fixed point accuracy of an acoustic magnetic synchronous cable fault location system?

A: The acoustic magnetic synchronous cable fault location system can achieve a fixed point accuracy of up to 0.1 m. This high positioning accuracy helps power utilities and cable maintenance teams quickly locate underground cable faults and reduce repair time.

Q3: Can an acoustic magnetic cable fault detector work in areas with strong background noise?

A: Yes. The acoustic magnetic cable fault detector supports three background noise reduction modes, including strong noise reduction, adaptive noise reduction, and no noise reduction. These functions help improve fault location performance in noisy urban areas, industrial sites, and power distribution networks.

Q4: How long can a portable acoustic magnetic cable fault locator operate after a full charge?

A: A portable acoustic magnetic cable fault locator uses a built-in 3.7 V lithium-ion battery with a capacity of 6700 mAh. It can work continuously for more than 9 hours, making it suitable for long-time outdoor underground cable fault testing.

Q5: Is this underground cable fault detection equipment suitable for outdoor power cable maintenance?

A: Yes. This underground cable fault detection equipment is designed for field applications. It features a sunlight-readable 800 × 480 color LCD display, a lightweight design, and a working temperature range of -10℃ to 40℃. It can be used for cable fault locating in power utilities, substations, and industrial power systems.
