Overhead Line Fault Tester

XFH-JKXGround Fault Locating Instrument for Overhead Lines with Small Current Grounding, suitable for overhead lines in small current grounding systems. In the event of a single-phase grounding fault that leads to the shutdown of the line, this device can be used to locate the grounding point.Please provide the Chinese content you would like translated into American English. Certainly.Positioning.

XFH-JKXIt's a portable device capable of fault location on multiple lines. The entire set consists of a transmitter (XFH-FS)、SensorsXFH-CG)、ReceiversXFH-JSComprised of attachments, after the faulted line is shut down, a transmitter applies ultra-low frequency high-voltage signals to the line to reproduce the fault. Sensors are hung on the line using insulating rods along the route to detect signals, and data is transmitted to a receiver on the ground wirelessly, displaying the measurement results. Before the fault point, the current persists; after the fault point, the current disappears. The line can be initially roughly segmented.Please provide the Chinese content to be translated. Certainly.Pinpoint locations quickly to determine fault positions.

Feature Highlights

1.Our equipment is designed for distribution networks with small current grounding systems, detecting various faults such as single-phase metallic grounding, arc grounding, and resistance grounding through transition.

2.Locating post-outage, particularly suitable for fault lines with cable branches.

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

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

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

6.Utilizing high-sensitivity sensors, the design features an open configuration, eliminating the need for closure, for easy 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 designed as a handheld unit.

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