The reasons why the generator is not producing electricity:
1. The power part cannot be started and there is no driving force to turn the generator.
2. The coupling between the power part and the generator is broken, unable to transmit power to the generator, the generator does not rotate.
3. The generator coil is broken and the generator excitation coil is broken.
4. The AVR is broken or the generator is broken.
5. The brush holder assembly of the brushed generator is broken (for example: the conductive ring is burnt out, the carbon brush is worn and has no contact force, etc.).
6 The diode of the brushless generator is broken and cannot generate a magnetic field.
1. You must first distinguish when the neutral line is. There is usually three-phase electricity coming out of the generator, that is, three live wires. Then there's the line problemPE and. Line N always difficult. Do you mean the neutral line, the PE line, the N line or the PEN line? This needs to be clarified
2. If it's line N, then it's normal for it to be loaded? The power generated by the equipment must be returned to the neutral point, otherwise the current loop is blocked. As for the voltage you measured, that means there is a grounding problem. There is no distinction between working earthing and protective earthing.
3. If it is a PE line, it is even more important. Attention, electrical safety must be analyzed in detail
4. If it's a PEN line, it is. is easy to understand and is equivalent to the N line.
