The generator voltage is managed by an "automatic voltage regulator", which is usually adjusted before leaving the factory.
However, due to a malfunction or imbalance caused by improper operation or problems with the regulator itself, the generator voltage will be high or low, or the voltage will be abnormal or even no voltage after load changes.
If this happens, if there are experienced masters nearby, you can ask them to check if there is an imbalance. The imbalance should be adjusted according to the instructions and should not be adjusted at will; is defective, it can only be sent for repair or update.
How are the positive and negative poles of the generator determined?
1 There is no 110 V voltage level in China, only 220 V;
2 110 V and 220 V are both single-phase voltages
3 If any; two voltage levelswith different phases of 110V voltage (like Japan and Hong Kong), the actual voltage when connected to the motor is 190V (110*1.732), which is still not enough in 220V
The generator emits alternating current and the actual voltage between the generator and the user. There is only one line connected to the generator (the user's live line and the other generator line are both grounded so the load can flow). If the electrical appliance is not turned on, there will be no current on the neutral line.
If one end of the generator is not grounded, it will not be able to produce electricity (the charge will not flow) and people will certainly not be electrocuted
