There are three major reasons for the unbalanced output voltage of the used generator
rental units in Dongguan
1. Unbalanced three-phase load.
2. The generator winding has a short circuit.
3, generator manufacturing defects (the number of turns of the three-phase winding is not equal).
At this time, the following situations may also occur:
2. The three-phase voltage is asymmetric, which causes the neutral point potential of the generator set to shift.
3. The neutral current is too large, which will increase the operating temperature of the distribution transformer, which will burn the transformer in severe cases.
4. Make some phase voltages high and decrease the other phase voltages
5.Burning out the generator, affecting normal power supply
Therefore, it is necessary to pay attention to the use of Dongguan second-hand generator
rental units, which cannot be unbalanced in three phases. If its output power cannot be changed, you need to choose a replacement wiring method to prevent damage to the generator set. http://ftfan.cn/
