1, electromagnetic interference with electronic equipment: negative sequence rotating magnetic field will interfere with the normal work of electronic equipment, especially sensitive electronic equipment, such as computers and mobile phones. , which will lead to its performance degradation or even damage.
2. Harmful to human health: Long-term exposure to negative sequence rotating magnetic field has a certain impact on human health.
3. Using shielding materials around electronic equipment, such as iron, aluminum and other metals, can effectively block the interference of magnetic field.
4. By introducing an appropriate positive sequence rotating magnetic field into the negative sequence rotating magnetic field, the magnetic field can be compensated and weakened.
