APF100 three-phase four-wire power supply system and electric control box, including all parts and device type selection. The active power quality filter and radiator have undergone finite element analysis, and the product runs stably.At present, most of our country adopts three-phase four-wire low-voltage power supply system, that is, 380V/220V neutral point directly grounded low-voltage power supply system. The power supply system has three phase wires (live wires) A, B, C, and a neutral wire. The reason why this neutral line is called the neutral line is because it is drawn from the neutral point of the secondary side of the transformer, and the neutral point of the secondary side is directly connected to the earth's zero potential, so it is called the neutral line. In the three-phase four-wire low-voltage power supply system, it is both the working neutral line and the protective neutral line. It is now called the PEN line, where PE is the protective neutral line and N is the working neutral line. Together, it is the PEN line, which represents the PEN line. The working zero line also serves as a protection zero line, commonly known as zero-ground unity.
