Hello:
——★1.We know that the neutral line is connected to ground (the neutral point of the power system transformer is grounded ), and the live wire has a voltage of 220 V.
——★2.The domestic generator produces two wires A and B, and the rated voltage between them two wire 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 neutral point grounding device of the transformer, the electrical safety rules are strictly stipulated: the grounding resistance should not be greater thanat 4 Ω, and general domestic 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.
There are two wires coming out of the 220V generator. Connect one to the hull, then ground it. The one connected to the hull and then to ground is the neutral wire. ;
380V generator. The neutral wire starting from the star point neutral wire is the neutral wire, which is connected to the generator shell, ground wire, etc. .
6-10KV is a non-grounding operating system. Directly powered high voltage loads are three phase and do not require a neutral line. There is no neutral line in the angular connection and the neutral line in. there is no need to remove the star connection. If low voltage electricity is supplied and the voltage ist reduced by the transformer, there will be a neutral line.
