Product Description

10KV single-phase cable small current ground fault locator/Overhead line grounding fault finder

It is suitable for fast and accurate location of ground point after power failure of 6-35KV fault line, small current grounding system of cable distribution network, detection of overhead line gold grounding, arc grounding, transition resistance grounding and other fault location.

After the fault line is shut down, the transmitter applies low frequency and high voltage to the line to make the fault repeat. The sensor is hung on the line with an insulated rod along the line to detect the applied current signal, and the data is transmitted wirelessly to the handheld receiver to display the measurement results. Before the fault point, the current signal continues to exist, and after the fault point, the current signal disappears. The fault location can be quickly determined by rough segmentation followed by precise fixing.

10KV single-phase cable small current ground fault locator/Overhead line grounding fault finder
Product features:
1, suitable for small current grounding system distribution network, detection of overhead lines of metal grounding, arc grounding, grounding through the transition resistance and other faults;
2, apply high voltage signal to reproduce the fault, constant current signal is stable, easy to detect;
3, low frequency signal to avoid the impact of system capacitance, can measure high fault resistance;
4, transmitter safety features: high voltage start blocking function, short circuit output allowed;
5, sensor and receiver wireless signal transmission, safe and reliable;
6, the transmitter can use the mains or automotive power supply, sensor and receiver dry battery power supply;
7. Small size and light weight of transmitter; The sensor is designed to reduce the volume and weight, and it is convenient to connect along the line. The receiver is hand-held design;
8, the receiver uses a large screen LCD display, showing the line current waveform and grounding status.
