For example, which generator wire is considered the neutral wire and the live wire, respectively?

The neutral line also comes from the power plant, and the neutral line is the neutral line. The generator only has three phases, but when passing through the step-down transformer (DY connection), the secondary side of the transformer brings out a cable from the neutral point. This is called the neutral line, which is also the zero line. mentioned by the poster.

The fact that the poster can think about the final destination of the neutral line shows that the poster is also a person who likes to think. Our electrical network is a mesh structure, and the neutral line comes out of it. this transformer will eventually be connected to another transformer.

I also suggest that the poster take a look at the TN system. The neutral line must be grounded.

Why does the alternator have a live wire and a neutral wire? Don't the two wires alternate between positive and negative? What is considered here is not grounding

Bonjour:

——★1.It is known that the neutral line is connected to the ground (neutral of the power supply the transformer point of the power system is grounded), the live wire has a voltage of 220 V to ground.

——★2.The domestic generator produces two wires A and B, and the rated voltage between the two wires is 220 V. Since the output wire ( A or B) of a home generator is not connected to ground, there is no distinction between live and neutral wires.

——★3. If you connect one wire (A or B) coming out of the generator to ground, then that wire is called the neutral wire, and the other wire is called the neutral wire. One wire is the live wire, which has a voltage of 220 V to ground.

——★4. For the grounding device of the neutral point of the transformer, the electrical safety rules are strictly stipulated: the grounding resistance must not begreater than 4 Ω, and the general household installation meets the requirements. It is very difficult and completely unnecessary to ground the grounding post, so home generators do not mark the neutral line.

These are not two lines which alternate between positive and negative, but three lines which alternate between positive and negative half-cycles .

You misunderstood. The alternator does not have two wires, but three wires. The three wires are phase wires (that is, all three wires are live wires). The waveform changes alternately depending on the SIN 120. -degree angle, it is called. For alternating current, there is no neutral wire inside the alternator. The neutral wire is added to the outside of the alternator.
