What is the difference between 3P+1 and 3P+N?
Feb 20 , 2025
The SPD combination modes include nP, nP+N, and nP+1. 3P+1 mode is used to raise the voltage (for example, the JLSP-GA750/100/3P+1 in the photovoltaic series is used to raise the voltage).The N in 3P+N refers to the addition of a gas discharge tube (under the action of this electric field, the gas inside the gas discharge tube begins to be ionized. When the external voltage increases to ...

Why do need to install SPD after installing lightning rod? What is the core difference between SPD and lighting rod?
Mar 19 , 2025
1. The role and limitations of lightning rods Intercepting direct lightning strikes: Lightning rods attract lightning through tip discharge and safely conduct lightning current into the earth through down conductors, protecting building structures from damage by direct lightning strikes. Limited protection range: The protection range of a lightning rod depends on its height and rolling ball r...

What is geodetic network monitoring? What is its technical core and engineering significance?
Apr 29 , 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 scen...

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...
