The solution to low voltage, how to solve low voltage at home

One way is to use a three-phase AC regulated power supply with a capacity greater than 50kva, as the starting current of the motor is large.

Another way is to use an inverter, which can solve the problem of difficult start-up and hot operation, and can achieve low-frequency start and high-frequency operation.

Select the drive based on the supply voltage and contact the drive manufacturer. If your voltage is too low, the inverter may not work properly, or use a three-phase AC regulated power supply.

Voltage, also known as potential difference or potential difference, is a physical quantity that measures the difference in energy generated by a unit charge in an electrostatic field due to different potentials. Its magnitude is equal to the work done by the unit positive charge to move from point A to point B due to the electric field force, and the direction of the voltage is defined as the direction from high potential to low potential. The SI unit of voltage is volts (V, abbreviated as volts), and the commonly used units are millivolts (mV), microvolts (V), and kilovolts (kV).

This concept is similar to the "water pressure" caused by the water level. It is important to note that the term "voltage" is generally only used in electrical circuits, while "potential difference" and "potential difference" are commonly used in all electrical phenomena.

The steps on how to solve the low voltage are as follows:1. If it is caused by a thin line and large resistance, in this case, the wire with a large cross-section needs to be replaced.

2. If the capacity of the transformer is small, it is also necessary to negotiate with the power company and ask it to replace the transformer.

3. If the power supply capacity is insufficient, you can only negotiate with the power supply bureau to increase the capacity. In addition, if the electrical load is heavy in summer, the voltage regulator can only be installed at home.

Low voltage is damaging to household appliances. In particular, it is more harmful to refrigerators and air conditioners, because the voltage is low, the starting current will become larger, and the temperature is high, and it is easy to burn the electrical appliances. Televisions are more resilient and less harmful.

What to do if the voltage at home is not enough1. If there are too many household appliances, you can install a voltage regulator.

to solve the problem.

2. If the wire is relatively thin, the thicker wire can be replaced.

3. If the circuit switch is in poor contact or disconnected, it is necessary to check the circuit, and then reinstall the switch or wiring.

4. If the load of the transformer is uneven, the load needs to be adjusted until the load is uniform.

What is the harm of not having enough voltage at home:When the voltage at home is not enough, the equipment is prone to failure, and even short circuit, burning, etc., in serious cases, so it is necessary to adjust and increase the voltage in time so that it can return to normal.

When the voltage is not enough, it is not good not to repair it yourself, but to contact professionals or staff of the circuit department to investigate the cause, and then prescribe the right medicine to solve the problem, so that there will be no more serious failure.
