DC Immune Single Nanocrystalline Cores For Current Transformer:
The DC immune tape wound cores are based on the tailor-made nanocrystalline material, and this constant permeability magnetic material with Permeability μ= 1500-4000. Our nanocrystalline alloy core has the characteristics of constant permeability and low remanent in a certain magnetic field range, besides, it also has a strong ability to resist DC component and a high anti-saturation performance, so the accuracy is better than the existing DC current immunity composite cores.
Magnetic Features:
Compared to conventional Metering cores , the DC immune nanocrystalline alloy core show following benefits:
- High linearity over the whole primary current range
- Easy to compensate
- Very low temperature drift
- DC immune according to IEC standard.
- Strong DC current immunity
- With high precision, the grade range 0.5–0.1, current range 1.5–500A.
Applications:
- DC current immunity transformers in electronic energy meter / watt-hour meter
- Metering transformer in electronic power system
