Open and close type nanocrystaylline core

Short Description:

The Current Transformer Core Permeability, the lower measurement error & higher measurement accuracy, The silicon steel Current Transformer 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.
