OVERVIEW
- After the power transformer completes the voltage ratio, winding resistance measurement, and no-load test, residual magnetism often remains in the iron core. If not handled in time, this residual magnetism may adversely affect the relay protection device and primary power transformer equipment. For example, the excessive excitation inrush current may not only cause the transformer to fail to close normally but also cause mechanical vibration of the transformer itself, thereby causing the winding structure to shift, which will not only shorten the service life of the power transformer but may even cause permanent damage to it in severe cases.
- To solve this problem, our company Wrindu has successfully developed the RDXC-3000A demagnetizer for sale. This is professional equipment specially designed to eliminate the residual magnetism of large power transformers, with the dual functions of demagnetization and verification demagnetization. It plays a vital role in protecting the transformer from the impact of excitation inrush current, ensuring the safe commissioning of the transformer, and extending the service life of the transformer.
- The instrument adopts advanced and reasonable composite current method technology, which can not only quickly demagnetize the transformer of the power transformer but also realize the quantification of residual magnetism detection. The process of detecting residual magnetism and eliminating residual magnetism can be completed automatically at one time, significantly improving work efficiency. It is particularly worth mentioning that for a three-phase transformer, only one phase needs to be demagnetized to achieve the desired effect. This feature makes the operation more time-saving and efficient.

FAQ
Q: How do you demagnetize a transformer?
A: To demagnetize a transformer, isolate it, connect a Demagnetization Tester, activate demagnetization mode, apply the process, verify success, and reconnect to the power source.
Q: Why do you need to demagnetize a transformer?
A: Demagnetizing a transformer removes residual magnetism, which is crucial after tests to prevent issues like excitation inrush currents. This ensures secure operation and extends the transformer’s lifespan.
Q: What is a demagnetizing effect in a transformer?
A: Demagnetization in a transformer removes residual magnetism from tests, preventing problems like excitation inrush currents. This ensures secure operation and prevents potential protective relays and primary equipment issues.
