Transformer & CT/PT Demagnetizer

The power transformer demagnetizer is a specialized demagnetizing device developed specifically for transformers and current/voltage transformers. Addressing the issue of residual magnetism after DC withstand voltage tests and winding tests on ferromagnetic components, the equipment employs intelligent alternating demagnetizing technology to quickly eliminate residual magnetism in the core. This effectively prevents faults caused by residual magnetism, such as inrush current, measurement errors, partial discharge, and abnormal operating noises, ensuring safe and stable operation of electrical equipment after maintenance and testing. The machine is easy to operate, has high demagnetizing efficiency, and is compatible with a wide range of models, making it widely applicable to power operation and maintenance, substation maintenance, and industrial and mining electrical testing scenarios. It is an essential piece of equipment for high-voltage electrical testing.

1. The instrument adopts an advanced AC/DC frequency conversion attenuation principle;
2. The test wiring is flexible, and demagnetization can be achieved by demagnetizing only one phase;
3. It has automatic current stabilization judgment and 16-bit AD data acquisition and processing functions;
4. One-click testing, one-click automatic fast demagnetization mode;
5. Rapid demagnetization: Demagnetization time is reduced from the traditional 30 minutes to a minimum of 2 minutes;
6. Significant demagnetization effect - single treatment increases demagnetization rate from 80% to over 90%;
7. Simple wiring.
8. The interface uses an LCD display screen with a full Chinese menu, providing a clear and intuitive display;
9. Applicable to eliminating residual magnetism before commissioning of large power transformers and instrument transformers of 35kV and above; especially for large-capacity transformers of 330kV and above.
10. This product is small in size and light in weight, making it very suitable for on-site use.
