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 Core’s application are limited because of their low magnetization and high cost.
Nano-crystalline cores are getting wider usage for the accuracy grade precious current transformer, because of its high permeability, high magnetization and lower cost in the field of power supply systems, power energy measurement and controlling systems, etc.
Product 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.
