The small current ground fault locator can detect faults on multiple lines

Recommended by DARUI Electric

 


It can locate faults on multiple lines. The complete set consists of a transmitter (JXD-100T), sensors (JXD-100S), a receiver (JXD-100R10), and accessories. After the faulty line is taken out of service, the transmitter applies an ultra-low frequency high voltage signal to the line to reproduce the fault. Along the line, use an insulating rod to hang the sensor on the line to detect the signal, and transmit data wirelessly to the receiver on the ground, which displays the measurement results. Before the fault point, the current persists; after the fault point, the current disappears. It can first perform rough segmentation, then pinpoint the location, thus quickly determining the fault position.




Suitable for small current grounding system distribution networks, detecting various faults on overhead lines such as single-phase metallic grounding, arc grounding, and grounding through transition resistance.

Locate after the line is out of service, especially suitable for faulty lines with cable branches.

Apply high voltage signal to reproduce the fault, the current signal is stable and easy to detect.

The ultra-low frequency signal avoids the influence of system distributed capacitance and can locate high-resistance faults.

Transmitter safety features: high voltage start-up interlock function, output allows direct short circuit.

The sensor uses a high-sensitivity sensor with an open design, no need to close, convenient for hanging on the line.

The sensor and receiver communicate wirelessly, safe and reliable.

The transmitter can be powered by mains or generator, while the sensor and receiver are powered by dry batteries.

The transmitter is small in size and light in weight; the sensor is designed with minimal size and weight for easy hanging along the line; the receiver is handheld.

The receiver uses a large-screen LCD display, showing sensor status, current waveform, and current value.
