Overhead Transmission Line Fault Indicator

XFH-JKXThe Overhead Line Fault Locating Device for Small Current Grounding Faults, suitable for overhead lines in small current grounding systems, can locate the grounding point after a single-phase grounding fault has caused the line to be shut down.Please provide the Chinese content to be translated. Certainly.Positioning.

XFH-JKXIt is a portable device capable of fault location across multiple lines. The complete set includes a transmitter (XFH-FSSensorsXFH-CG)、Receiver (XFH-JSComprising the attachment, after the faulty line was shut down, ultra-low-frequency high-voltage signals were applied from the transmitter to recreate the fault. Sensors were hung on the line using insulating poles along the route to detect the signals, and data was transmitted to the ground receiver wirelessly, with the receiver displaying the measurement results. Before the fault point, the current persisted; after the fault point, the current disappeared. A preliminary rough segmentation can be conducted first.Please provide the Chinese content to be translated. Certainly.Pinpoint locations quickly to determine fault positions.

Feature Highlights

1.The distribution network, suitable for low-current grounding systems, detects various faults such as single-phase metallic grounding, arc grounding, and grounding through resistance transition in overhead lines.

2.Location post-outage, especially suitable for fault lines with cable branches.

3.Applying high-voltage signals to reproduce faults, the current signals are stable and easy to detect.

4.Ultra-low frequency signals minimize the impact of system distributed capacitance, enabling precise location of high-resistance faults.

5.Transmitter Safety Features: High-voltage start interlock function, direct short-circuit capability for output.

6.The sensor utilizes a high-sensitivity sensor, with an open design that does not require closure, making it convenient for attachment to the line.

7.Sensor and receiver wireless communication transmission is secure and reliable.

8.Transmitters can be powered by municipal electricity or generators, while sensors and receivers are powered by dry batteries.

9.The transmitter is compact and lightweight; the sensors are designed for miniaturization in size and weight, making them easy to hang along the route; the receiver is handheld.

10.The receiver features a large LCD screen, displaying sensor status, current waveforms, and current values.
