The function of voltage stabilizer

A voltage regulator is a device that can provide a stable voltage to the electrical equipment connected behind it to ensure its normal operation. So the key role of a voltage regulator is to solve voltage problems.
1. Voltage deviation: Adding a voltage regulator can effectively solve the problem of voltage deviation in the power grid and provide a high-quality operating environment for electrical equipment.
2. Voltage fluctuation (power grid mutation less than 10%): Increasing voltage regulators is the most effective way to solve voltage fluctuations. It can provide a relatively good operating environment for electrical equipment.
3. Voltage flicker (power grid mutation greater than 10%): Adding a voltage regulator (power grid mutation less than 20%) can improve the impact of lightning disasters, operating overvoltage, and large capacity impact loads (such as electric arc furnaces) caused by severe voltage fluctuations in the power grid.
4. High order harmonics: The voltage regulator itself cannot solve the problem of high order harmonics. When the voltage regulator works in the presence of high order harmonics, it needs to add a sampling and filtering system (true effective value sampling).
5. Three phase asymmetry: Adding a voltage regulator to an isolation transformer is an effective method to solve voltage asymmetry. In most cases, it can meet the national allowed value of 2%, with a short-term limit of 4% and a single user limit of 1.3%.
