The instability of the grid voltage is a major problem in many countries. The main reasons for this are that, on the one hand, the number of electrical appliances in summer cottages is rapidly increasing. On the other hand, the power of the power system is no longer sufficient to meet the needs of all consumers. As a result, network surges and drops occur, which lead to equipment malfunctions or complete failure.
To solve the problem of poor power supply, many villa residents install voltage stabilizers to protect their high-end facilities from voltage fluctuations. In our article, we will tell you about these devices and which are best suited to protect the electrical equipment used in villas.
Reasons for unstable voltage in villas
A large number of electrical appliances are switched on at the same time. This situation can cause the grid to be overloaded, which usually happens on weekend evenings, when summer residents return home almost simultaneously and switch on their appliances, or when the temperature drops and many owners need to heat their homes, which contain powerful appliances. For example, when neighbors in summer houses use power tools or pumping equipment with high starting currents, a lot of energy is consumed. Another case is a line accident caused by natural disasters (such as lightning strikes on power lines) or poor installation quality.
What voltage does the villa's load require?
Determining the signal value required to supply power to the consumer is important. Usually, this information is stated on the device nameplate. If not, you can check with the manufacturer.
The villa's most sensitive electricity consumer is the energy-dependent heating boiler. It usually requires a voltage value that does not deviate by more than 5% from the nominal 220V or 230V (i.e., it can operate in the 220-240V range).
Modern models of refrigerators and washing machines are also very sensitive to surges. They usually contain complex electronic systems that trigger a protective shutdown if the signal deviates from the nominal value by more than ±5%.
Water pumps usually operate with a voltage deviation of no more than ±10% of the standard value.
Consumers with pulsed power supplies (e.g., TVs, laptops, PCs, video players) are less sensitive to surges and can continue to operate with voltage dips of up to 100 V. However, for almost all appliances, the upper threshold is 240 V, and in rare cases, 250 V.
Which voltage stabilizer is best for a villa?
It is best to install a high inverter stabilizer in the villa, which can operate normally when there are large fluctuations and deviations in the network while providing high-quality electricity for the electrical appliances. Why is there a significant difference between a high inverter stabilizer and a traditional voltage stabilizer?
