Since the problem of low three-phase electrical voltage can involve many reasons, a series of measures are needed to solve this problem. Here are some common workarounds:
1.Check the power cord.
First of all, you need to check whether the power cord is working properly. If the power cord has problems such as breakage, poor contact, or aging, it can cause the voltage to drop. Therefore, the power cord needs to be carefully inspected to ensure that it is intact and replaced with a new one if necessary.
2.Increase transformer capacity.
If there is no problem with the power cord, then it may be that the transformer is undercapacity, causing the voltage to be low. In this case, the capacity of the transformer needs to be increased to provide greater current and voltage, thus increasing the voltage of the three-phase electricity.
3.Adjust the phase balance.
If the phase in the three-phase electricity is unbalanced, it will also lead to a low voltage. In this case, the phase balance needs to be adjusted to ensure that the voltages of each phase in the three-phase electricity are equal. The voltage of each phase can be balanced by adjusting equipment such as transformers and capacitors.
4.Check the load.
If the load is too large, it will also cause the three-phase electrical voltage to be low. In this case, it is necessary to check and reduce unnecessary loads to reduce the burden on the wires and thus increase the voltage.
5.Install the voltage regulator.
If none of the above solves the problem, then a voltage regulator may need to be installed to stabilize the voltage. The voltage regulator can automatically adjust the input voltage to ensure that the output voltage is stable.
In short, solving the problem of low three-phase electric voltage requires corresponding measures to be taken according to the specific situation. Before taking any action, it is essential to ensure that the power supply has been turned off and that a professional has it inspected and repaired.
