Three-phase Four-wire Wiring System For Automatic Voltage Regulators

The 10 kva automatic voltage stabilizer input and output are both four-wire (three live wires + one neutral wire). The live wires are typically yellow, green, or red, the neutral wire is light purple, and the ground wire is yellow-green. In a three-phase four-wire power system, current is transmitted through three independent live wires (L1, L2, L3), providing a balanced current load. The neutral wire (N) is responsible for current return, and the ground wire (PE) ensures the equipment's grounding protection. To ensure stable operation of the power equipment, the 10 kva avr design fully considers the requirements of this power system and can adapt to voltage fluctuations under different loads. The three-phase four-wire power system effectively reduces current interference through precise voltage control, ensuring stable output and preventing equipment damage due to voltage instability. The 100 kva stabilizer utilizes this structure to optimize power supply, maintaining the voltage level required for equipment operation to ensure long-term system reliability.
