（1） Compensation principle
This compensating voltage regulator is based on the principle of electromagnetic induction to achieve stable voltage regulation. When the input voltage changes, the compensation winding inside the voltage regulator will automatically adjust the magnetic flux according to the voltage fluctuation. By changing the number of turns or current magnitude of the compensation winding, a compensation voltage opposite to the voltage fluctuation is generated. After superimposing this compensation voltage with the input voltage, the output voltage is maintained at a stable level of 380V. For example, when the input voltage decreases (under voltage condition), the compensation winding generates an increased voltage component to boost the output voltage; When the input voltage increases (overvoltage situation), the compensation winding generates a reduced voltage component to maintain the stability of the output voltage.
（2） The significance of 1000KVA capacity
Meet the high power demand
The 1000KVA capacity design enables this voltage regulator to cope with large-scale power loads in the distribution room. In large factories, commercial complexes, or data centers, where there are numerous electrical devices with high power consumption, the total electrical load is relatively high. This high-capacity voltage regulator can provide stable voltage for all connected devices, ensuring that even under high load conditions, there will be no abnormal device operation caused by insufficient voltage. For example, in a power distribution room of a factory with multiple large processing equipment and automated production lines, a 1000KVA voltage regulator can meet the power requirements for simultaneous start-up and operation of these devices.
Ensure the reliability of power supply
Appropriate capacity is crucial for ensuring the reliability of power supply. If the capacity of the voltage regulator is too small, it may not be able to provide sufficient voltage support during peak power consumption or equipment startup, resulting in a significant drop in voltage and affecting the normal operation of the equipment. However, excessive capacity can lead to resource waste and increased costs. The capacity of 1000KVA fully considers the typical load situation of the distribution room in the design, achieving a good match between power supply capacity and actual demand, and ensuring the stable operation of the power system.
3、 The advantages of adjustable undervoltage and overvoltage function
（1） Dealing with complex power grid environments
In actual power supply, the grid voltage may be affected by various factors, such as changes in grid load, power transmission failures, lightning strikes, etc., resulting in undervoltage or overvoltage phenomena. The adjustable undervoltage and overvoltage function of the three-phase 380V compensating regulator enables it to flexibly adapt to this complex power grid environment. Users can set the threshold for undervoltage and overvoltage according to the actual situation. When the grid voltage exceeds the normal range, the voltage regulator can quickly activate the adjustment mechanism to protect electrical equipment from damage caused by abnormal voltage. This adjustable function improves the adaptability of the voltage regulator to different grid conditions and enhances the stability of the entire power system.
