Solution to voltage instability in mountainous/remote rural areas - installing i

The rapid increase in electricity consumption and excessively long power lines in mountainous or remote rural households, coupled with relatively outdated power supply facilities, can cause unstable (mainly low) voltage in homes under tight power supply conditions, resulting in many household appliances not functioning properly and even leading to malignant accidents such as burning out appliances and causing fires.
To ensure the safety of household electricity, an intelligent voltage regulator can be installed when the power supply voltage at home is unstable (mainly low voltage).
When purchasing a voltage regulator, the following three points should be noted:
One is full functionality. The purchased voltage regulator should have the following three functions: voltage stabilization function, which can stabilize the voltage of low voltage 125-165 volts or high voltage 250-270 volts between 200-230 volts, enabling household appliances to work normally; Automatic power-off function, which can automatically cut off the power supply when the input voltage is higher than 270 volts or lower than 125 volts and the output voltage is higher than 235 volts; The delay function allows for a delay of 4-8 minutes to activate the output power when there is a sudden call after a power outage. When choosing a household voltage regulator, it is important to pay attention to whether the three basic functions mentioned above are reliable.
The second is to determine the appropriate power. The apparent power of household voltage regulators ranges from 500 watts to 8000 watts, with prices ranging from tens to hundreds of yuan. The power of a voltage regulator should be selected based on the power of the appliance, but not just the rated power consumption of household appliances, as many appliances have much higher current than the rated current when starting, such as refrigerators, air conditioners, fans, etc. Generally speaking, air conditioners should choose a voltage regulator with three times their power, refrigerators should choose one with five times their power, and other electrical appliances should have lower requirements. When purchasing, it is also necessary to consider the situation where several appliances are used together, and the power should be higher rather than lower, so that the output power of the voltage regulator is sufficient to meet the peak current surge of household appliances.
The third is to purchase qualified products. At present, most of the voltage regulators on the market are produced by small factories in family workshops, and most of them are of poor quality. The packaging should be intact, with complete instructions, certificates of conformity, and warranty card attachments. The manufacturer's name and address should be indicated on the instructions and product. We absolutely cannot buy "three no" products for the sake of cheapness and bury hidden dangers of accidents.
