Using an electric pen to measure is the stupidest and most dangerous way, use a multimeter! ! ! ! You don’t even know what happens when your laptop shuts down! The multimeter can tell the difference by connecting a wire and grounding it! ! ! ! Gasoline engines are all 220V, not 380V, unless you customize them! Generator Professionals
Is the neutral line of a single phase gasoline generator loaded?
I'm thinking:
First of all, it's best to use a digital generator generator to ensure the quality of the power supply to avoid adverse effects on electrical appliances;
Second, the electrical box should not be connected to the mains;
p>
Simply choose a single phase for the three live wires in the electrical box. Connect it to the motor with the neutral line.
If the motor does not have a circuit breaker, youneed to connect it yourself;
The notices are for reference only, pay attention to safety.
In different meanings of 220V electricity, which is what you call big electricity, the neutral wire is connected to ground, so when testing with an electrical test pen, only the wire live is live and the neutral wire is not.
The winding of your single-phase generator is not connected to earth, so there is no distinction between live and neutral wires. In other words, your generator is isolated from ground, so both pins have voltage to ground and there is no difference.
Regarding the UPS server that you said is not working, the reason may be that the electrical voltage or frequency emitted by your generator exceeds the operating requirements of the UPS, and it has nothing to do with whether it is grounded or not. not.
Can youmeasure if the voltage is too low or too high? Also, does UPS have corresponding alarms?
