Nanocrystalline Current Transformer Core Product Description
It is well known that the higher CT core permeability, the lower measurement error & higher measurement accuracy. The silicon steel CT core can not get enough measurement accuracy under the situation of low Ampere-turns of small turn ratios . And the Fe-Ni Permalloy Coreas application are limited because of their low magnetization and high cost.
Nano-crystalline cores are getting wider usage for the accuracy grade precious current transformers, because of its high permeability, high magnetization and lower cost in the field of power supply systems , power energy measurement and controlling systems, etc.
Nanocrystalline Current Transformer Core Characteristics
- High Permeability & High Saturation induction Bs - Increase CT's accuracy, leavel , smaller volume & High linearity.
- Good temperature stability - Keep stable from -55 ℃to 120℃for long time .
Applications
- Energy Meters and Smart Grids:
The high accuracy and linearity make them ideal for precision measurement in electronic energy meters and smart grid equipment.
- Power Monitoring and Control:
They are used in measurement-grade CTs for monitoring and controlling power distribution systems.
- High-Frequency Applications:
Nanocrystalline cores perform well up to MHz frequencies, making them suitable for high-frequency power supplies, inverters, and other power electronics where minimizing energy loss is critical.
