For consumers who do not have knowledge of electricity, they do not know what causes the household voltage to be too high, and do not know how to solve the problem when it occurs. Therefore, this article tells you the reasons for the household voltage to be too high and the corresponding solutions, and how the automatic voltage regulator can help you save money.
Main reasons for high voltage in household electricity
Grid supply problems: The grid supply voltage exceeds the normal range, especially on lines with large load fluctuations.
Problems with the transformer neutral interface or residential public zero connection: If there are problems with the transformer neutral interface or residential public zero connection, the voltage may increase.
Power company management problems: Some technical problems when the power company manages the power grid, or voltage fluctuations caused by changes in power demand.
Equipment failure: Failure of electrical equipment, such as circuit short circuits, capacitor problems, etc., may cause a voltage increase.
Weather conditions: Weather conditions such as strong lightning activity or storms may affect power transmission lines and cause voltage fluctuations.
Wire aging: Aging wires or using unqualified wire materials may cause voltage instability.
User behavior: The family uses too many electrical devices, exceeds the loop power supply capacity, or changes the voltage level of electrical devices without authorization.
No neutral line in the household line: The user’s household line has no neutral line, or the neutral grounding wire at the output end of the transformer is broken or poorly grounded, which may cause a voltage increase.
Long outdoor power supply lines or small cross-sections of external wires: resulting in large line losses and unstable voltage.
Irrational indoor wiring: The cross-section of the main wire is too small, and the voltage drop is large when the equipment with high power consumption starts, resulting in unstable voltage.
Neighbors use high-power electrical appliances: It affects the voltage of their own homes and causes unstable voltage.
Methods to solve high voltage of household electricity
Check the common connection of the neutral line: Check whether there is a problem with the neutral line interface of the transformer or the common zero connection of the residence.
Test with a mechanical pointer multimeter: Get a more accurate voltage reading.
Check electrical equipment regularly: Repair or replace problematic parts in time to ensure their normal operation.
Reasonable use of electrical equipment: Avoid overloading electrical equipment and comply with relevant electrical use regulations.
Strengthen the stable management of the power grid: Power companies should strengthen the stable management of the power grid to ensure the stability of the voltage.
Choose wire materials with guaranteed quality: Choose products with guaranteed quality when installing wires, and check the condition of the wires regularly.
Can an Automatic Voltage Regulator Save You Money?
Automatic voltage regulators can help you save money to a certain extent. The main function of this device is to automatically adjust when the voltage is unstable, protect home appliances, and prevent appliances from consuming more energy when the voltage fluctuates, thereby extending the life of appliances and reducing energy waste.
Especially for energy-saving home appliances, such as LED TVs, energy-saving refrigerators, etc., using an automatic voltage regulator can ensure that they work under stable voltage and improve energy-saving effects.
However, although the automatic voltage regulator can reduce energy waste, the actual electricity bill savings may not be significant, because the energy-saving effect is affected by many factors such as the use time and power of the appliance.
Therefore, when choosing whether to use an automatic voltage regulator, it should be decided based on the use of individual appliances. If there are many high-end appliances in the home or the voltage fluctuates greatly, it may be more cost-effective to use an automatic voltage regulator. But if you buy it just to save electricity, it may not be the wisest choice.
