    A neutral current eliminator can be installed to eliminate the problem of excessive neutral current.

    Reasons why the neutral current of a three-phase load will exceed the live current:

    1. The three-phase imbalance is caused, but the neutral line current will not exceed a certain phase.

    2. Caused by the third harmonic generated by the load, the neutral current not only exceeds the live wire current, but also reaches 2 to 3 times of the live wire current.

    Solution: 1. In the first case, evenly distribute the three-phase load to avoid the zero line current caused by the three-phase unbalance.

    2. In the second case, install a neutral current eliminator to eliminate the third harmonic neutral current.

    Long-term overcurrent of the neutral line can also cause fire, and the installation of the neutral current eliminator of Guangzhou Sansi Electric Technology can solve the fundamental problem of overcurrent of the neutral line. The neutral line current elimination rate is more than 90%.

    The neutral line current is too large and the cable is seriously heated, indicating that the three-phase load is seriously unbalanced. There is only one way to solve the problem, which is to adjust the load distribution so that the three-phase load is balanced as much as possible.

    If the neutral line current is too large, it is a serious imbalance of the three phases, and the phase is re-divided.

It means that the 0 wire of this route in the electrical box is not connected and loosened, or the 0 wire of your house in the main distribution box is loose, and the old connection method of installing a fuse on the 0 line should focus on checking this fuse. In short, the 0 line contact is not good. It must be repaired quickly, otherwise there may be certain safety hazards.

When the zero line (points A and B in the figure) is open, the phase wire is connected to point A through the electrical appliance, and if it touches point A, it is equivalent to connecting the electrical appliance and the human body resistance in series to the earth, and the electrical resistance is usually smaller, so the voltage distributed by the human body is larger, which will cause an electric shock accident. Therefore, it is not possible to set the switch on the zero line.
