■ Product Overview
Xsn-2080 Overhead line small current grounding fault finder is suitable for single-phase metallic attribute grounding, grounding through arc, grounding through transition resistance and other fault types; Ultra-low frequency signals can avoid the influence of system capacitance,
Low resistance to high resistance fault can adapt; Whether a line has branches, whether it is an overhead line branch or a cable branch, and whether a transformer is connected to the line has no impact on the device.
Fault location is carried out after a fault occurs on the line and the transmitter applies high voltage to the fault line to reproduce the fault. Ultra-low frequency current flows from the transmitter to the fault point and flows back to the earth through the transition resistance
The transmitter; Along the line, the sensor is connected to the line through an insulating rod to detect the current, and the analog signal is converted into a digital signal, which is then transmitted out wirelessly. A receiver on the ground receives sensing
The wireless signal sent by the device displays the measurement results intuitively on the LCD screen.
