No need.
The output of three-phase generators generally does not have a ground wire. The neutral line is actually the neutral line, which is the midpoint where the tails of the three-phase lines are connected. Under normal circumstances, the neutral line has voltage, but the voltage is not too high, only a few volts or tens of volts.
The neutral wire of the generator does not need to be grounded. It must be connected to the neutral wire of electrical devices such as motors. The ground wire on the case must be grounded. Since the mains neutral line is often in an unbalanced three-phase state, if it is connected to the generator neutral line, a current will flow through it, causing electrolysis or even burnout. Generator neutral line refers to the neutral point wiring of the generator Y connection. In theory, it must be connected to the neutral line of the electrical equipment.ique, like a three-phase, five-wire system. , the neutral line is not grounded. The conductor wire of the power generation equipment housing is a ground wire.
It is inevitable that the neutral point of the generator will be grounded. Simply convert the grounding point of the low voltage system from the transformer to the generator. The generator is a three-phase to four-phase. wire, so the fourth wire is ready to be connected to the TN--C system, that is, it must be grounded;
If the neutral point of the generator does not is not grounded, due to the three being unbalanced. -Phase load, the neutral point will move, and some phase voltages will increase, some phase voltages will decrease, which will affect the normal operation of electrical equipment;
