About the product
This instrument is a specialized device for eliminating residual magnetism in large power transformers. It plays an extremely important role in protecting transformers from the impact of excitation inrush currents, ensuring safe operation, and extending the service life of transformers.
During normal operation and testing of large-capacity transformers, residual magnetism will be generated in the iron core. When the transformer capacity is large, the harm of residual magnetism will also increase accordingly. Residual magnetism may cause misoperation of relay protection devices, leading to transformer operation failure; At the same time, residual magnetism may also cause abnormal test results and affect the power quality after power transmission. Therefore, attention should be paid to abnormal phenomena or faults caused by residual magnetism during transformer operation. For this reason, our company has developed a series of transformer demagnetization products. Our company is one of the earliest domestic manufacturers to develop and produce demagnetizing instruments, and has accumulated a lot of practical experience.
This Transformer Degausser is a new-generation demagnetizer independently developed by our company. It adopts advanced and reasonable composite current method technology, which can quickly demagnetize power transformers and current transformers. For three-phase transformers, only one phase needs to be demagnetized, which is more time-saving and efficient.
Main Technical Features
- We adopt an advanced composite current degaussing method, and the current impact is small in the degaussing process.
- High demagnetization efficiency, as only one phase of a three-phase transformer needs to be demagnetized, greatly saving time.
- The progress percentage of the demagnetization process and the demagnetization progress indicator bar are intuitive and clear, and the demagnetization current curve graph is displayed.
- The wiring is simple, and the test line of the DC resistor can be used directly in demagnetization
- We adopt a digital current adjustment, ensuring high current control accuracy.
- We have a 5-inch color touch screen control, which is easier to operate.
- Test results are automatically stored. Demagnetization current data is recorded without the need for manual storage.
- Reports can be printed directly and stored on a USB flash drive.
- High level of After setting the parameters, all measurement work can be completed with just one key press.
- The software interface is simple and intuitive, with clear menus for storage, report export, printing, and more.
