Use Automatic Voltage Stabilizer When Industrial Power Voltage Is Unstable

In my country, industrial electricity is three-phase 380v, while some foreign countries use three-phase 400v. Imported domestic power needs to be installed with a three-phase transformer from 380v to 400v. Many merchants only open accounts for three-phase electricity for the entire factory, that is, only three-phase electricity is available. 220V electrical equipment can only be connected to a live wire and a neutral wire in the three-phase circuit. However, the single-phase power consumption of many factories is very large, even far exceeding the three-phase electrical equipment. High-power single-phase electricity will cause three-phase voltage imbalance, so it is difficult to keep the three-phase electricity at a constant voltage value. There is a voltage difference in the three-phase electricity, and this difference is called three-phase imbalance. Due to the three-phase imbalance, for some large precision equipment, there may be problems such as unstable work, shortened life, failure, and high defective rate of products. It is difficult for ordinary Automatic Voltage Regulator to achieve automatic balance of three-phase voltage. At this time, an automatic voltage stabilizer can be used to solve the three-phase voltage imbalance. The automatic voltage stabilizer has the function of independent voltage regulation of three phases. The automatic voltage stabilizer is controlled by a DSP microcomputer, which collects signals from each phase and calculates the imbalance of each phase voltage. The voltage signal is sent to the drive circuit, which then adjusts the corresponding coil turns ratio according to the voltage difference in the control circuit signal to achieve the rated voltage value. The automatic voltage stabilizer can adjust and stabilize the voltage of each phase to the rated voltage value, so that the three-phase electrical equipment can use the rated standard voltage, large precision equipment can work and operate normally, and can improve productivity and product qualification rate.
