All our signal loops are indoors, so why do we need to consider surge protection device? May 14 , 2025
Although the entire data loop is installed next to the power loop, or is installed very close to the building's steel structure or lightning rod, the ground potential of the AC power supply of the communication interface equipment connected to the data loop is seriously unbalanced, so the data communication interface is easily damaged. The ways in which lightning can cause damage to electronic dev...

What is geodetic network monitoring? What is its technical core and engineering significance? May 28 , 2025
Earth network monitoring is a comprehensive detection technology for grounding systems of power, railway, communication, petrochemical and other facilities. The core parameters include grounding resistance (R), conductivity (contact resistance) and soil resistivity (ρ). The grounding system forms a low-impedance path with the earth through metal conductors, discharging fault current in scenarios s...
