When IT system (with N line):
TN-C-S system:

The N line and PE line of the system are combined into a PEN line from the low-voltage side of the transformer. At this location, only a (3P) surge protector needs to be installed between the phase line and the PEN line. After entering the main distribution box of the building, The PEN line is divided into N line ^ PE line and independent wiring. The PEN line is connected to the general equipotential grounding busbar in the building to connect to the earth.

N-C-S system

TN-S system:

The N line and PE line of the system are only connected at the outlet end of the low-voltage side of the transformer and connected to the ground. Before entering the general distribution box of the building, the N line and the PE line are independently wired, and the phase line and the PE line must be connected Install a surge protector.

TN-S system

TT system:

The N line of this system is only grounded at the neutral point of the transformer, and the N line and the PE line are strictly separated. Therefore, it is necessary to install a surge protector between the phase line and the N line, and a switch-type surge protector is often installed between the N line and the PE line.

TT system

When IT system (with N line):

The neutral point of the transformer of this system is not grounded, and there is an N wire in the line.
