Household appliances need to be equipped with automatic high-voltage and low-voltage protectors for several reasons, including reducing line loss, ensuring safety, preventing equipment damage, and extending equipment life.
☆ Reduce line loss:
High-voltage power transmission reduces current by increasing voltage, thereby reducing the problem of severe heating of wires due to excessive current and reducing line loss. This is because according to Joule’s law, heat is proportional to the square of the current. By increasing the voltage, the current can be significantly reduced, thereby reducing line loss.
☆ Ensure safety:
Low-voltage power distribution is for safety reasons. It reduces current by reducing voltage to avoid safety hazards caused by excessive current. In household electricity use, an appropriate voltage is crucial to ensure user safety. Excessive voltage may cause damage to electrical appliances or personal injury.
☆ Prevent equipment damage and extend equipment life:
For household electrical equipment, it is essential to install over- and under-voltage protectors, especially in areas with unstable power grid quality. Over- and under-voltage protectors can effectively monitor and adjust voltage to ensure the safe operation of household electrical equipment and avoid equipment damage or performance degradation caused by abnormal voltage.
This is especially important for the increasing number of expensive electrical appliances in modern homes, which can significantly reduce the cost of repairs and replacements.
☆ Enhance the awareness of electricity safety:
As people’s safety awareness increases, more and more families begin to pay attention to electricity safety. Installing an over-voltage and under-voltage protector is not only an effective means of protecting the home power system but also prevents various safety hazards caused by voltage problems and ensures the personal safety of family members.
What are high voltage and low voltage?
The difference between high and low voltage in the power system refers to the difference in voltage levels. In the process of power transmission, the voltage is divided into two stages: high and low voltage. High voltage generally refers to a voltage level of 110 kV (kV) or above, while low voltage usually refers to a voltage level of 220 V (V) or below. The difference between these two voltages is applied to different electrical equipment and scenarios.
Summary of automatic high-voltage and low-voltage protectors
Equipping household appliances with automatic high-voltage and low-voltage protectors is an important measure to ensure the efficiency and safety of power transmission, which is of great significance for protecting the safety of household electrical equipment and family members.
