Different Power Supply Earthing System Selection
TN-C-S system
In this system, the N line(neutral line), PE line(earthing line) from the low voltage side of transformer combined as one PEN line, at this position, only need to install the SPD between phase line and PEN line, after come into building’s main distribution box, PEN line separate into independent N line and PE line, the PEN line is connected to the earthing bar of the building’s main equipotential connection to access to earth. After enter into main distribution box, N line and PE line independently, need to install SPD between them.
Can select SP1-B type, SP1-C type and SP1-D type product as Class I, II, III protection.
TN-S System
In this system, the N line(Neutral line) and PE line(earthing line) only joint connecting to earth at the outgoing terminal of low voltage side of transformer. Before come into the building’s main distribution box, N line and PE line is independently wiring, between phase line and PE line, N line and PE line all need to install SPD. Can select SP1-B type, SP1-C type and SP1-D type product as Class I, II, III protection.
TT System
In this system, the N line(Neutral line) only grounding at the neutral position of transformer. N line and PE line strictly separate wiring. Therefore need to install SPD between phase line and N line. Install gap surge protection device between N line and PE line. Can select SP1-B type, SP1-C type and SP1-D type product as Class I, II, III protection. Select SDS-40 type product as protection between N line and PE line after Class II protection.
It System
In this system, the neutral point of transformer is not grounding, no neutral N line in the circuit. Can select SP1-B type, SP1-C type and SP1-D type product as Class I, II, III protection.
