■ Product Overview
VS-2080 overhead line small current grounding fault locator is suitable for single-phase metallic grounding, arc grounding, transit resistance grounding and other fault types; Ultra low frequency signal can avoid the influence of system capacitance, and can adapt to faults from low resistance to high resistance; Whether the line has branches, whether it is overhead line branches or cable branches, and whether the transformer is connected to the line has no impact on the equipment.
Fault location is carried out after the line is out of service due to fault. The transmitter applies high voltage to the fault line to reproduce the fault. The ultra-low frequency current flows from the transmitter to the fault point, enters the earth through the transition resistance and flows back to the transmitter; Along the line, the sensor is connected to the line through the insulating rod to detect the current, and the analog signal is converted into digital signal and transmitted outward through wireless mode. The receiver on the ground receives the wireless signal sent by the sensor and visually displays the measurement results on the LCD screen.
