This instrument is a specialized equipment for cleaning residual magnetism in large power transformers, with demagnetization and verification demagnetization functions. It plays an important role in protecting transformers from the impact of excitation inrush current, ensuring smooth operation, and extending the lifespan of transformers.

After voltage ratio, DC resistance measurement, and no-load test, residual magnetism will remain in the iron core of power transformers. If residual magnetism is not treated, it may have many adverse effects on the relay protection devices and equipment of power transformers. Excessive excitation inrush current can cause the transformer to fail to close, as well as mechanical vibration of the transformer itself, resulting in displacement of the winding structure, affecting the service life of the power transformer and even causing long-term damage.

For this purpose, our company has developed a series of transformer demagnetization products. The demagnetization analyzer for power transformers adopts advanced and reasonable composite current method technology, which can quickly demagnetize the transformers and quantify the residual magnetism detection. The detection and cleaning of residual magnetism are automatically completed. For three-phase transformers, demagnetizing only one phase is sufficient, which saves more time.
