What are the requirements for the installation of the connecting wires at both ends of the SPD?
Apr 08 , 2025
Regardless of TN system or TT system, the connection wires at both ends of the SPD connected to the live conductor and PE line should be short and straight. The IEC standard stipulates that the total length of the SPD connection wire should not exceed 0.5m. This is because the lightning impulse current has high-frequency characteristics, and the lightning impulse overvoltage applied to the ...
