DC Current Immunity Composite nano Cores & Amorphous cores:
The DC current immunity composite current transformer core is composed of high permeability nanocrystalline magnetic core and anti-saturation amorphous magnetic core, so that the current transformer can still work normally under the condition of DC component, besides, it has small Ratio difference and Angle difference. The composite magnetic core not only has high saturation magnetic induction intensity Bs, but also has high permeability and low iron loss, which ensures the measurement accuracy when there is small or no DC component.
Magnetic Features:
- Strong DC current immunity.
- Good temperature stability.
- With high precision, the grade range 0.5–0.1, current range 1.5–200A.
- Competitive price and excellent quality
Applications:
- DC current immunity transformers in electronic energy meter / watt-hour meter
- Metering transformer in electronic power system
