Frequently Asked Questions
How to measure B-H curve for nanocrystalline cores?
To measure the B-H curve, apply a sinusoidal voltage to the primary winding and measure both the secondary voltage (proportional to flux density B) and primary current (proportional to magnetic field H). Our tool calculates the exact relationships using Faraday's law and Ampère's law.
What makes nanocrystalline cores better than ferrite for EMI filters?
Nanocrystalline cores offer superior performance in EMI filter applications due to their high permeability (up to 100,000), excellent frequency stability, and lower core losses compared to ferrite cores. They maintain stable performance across wide temperature ranges.
How accurate are the calculated core specifications?
Our calculations use industry-standard formulas with typical material properties. Results are suitable for initial design and analysis, but should be validated through physical testing for critical applications. The tool provides ±5% accuracy for most parameters.
Can I use this tool for current transformer design?
Yes, this analyzer is excellent for current transformer applications. Input your CT core dimensions and test parameters to analyze linearity, saturation characteristics, and accuracy class compliance for revenue metering and protection applications.
