Nano Current Transformer Core

Model: NR Series

Introduction:

Higher permeability achieves lower measurement error and higher measurement accuracy. The current silicon steel CT cores cannot achieve the ideal measurement accuracy under the situation of low Ampere-tums or small turn ratios, and the Fe-Ni Perm-alloy core application is limited because of its low magnetization and high cost. However, nano-crystalline cores are getting more widely used in 0.2，0.2s, 0.1 accuracy grade current transformers than precious generations. This is due to their properties of high permeability, high magnetization as well as lower cost in the Iow Hc field of power supply systems, power energy measurement and control systems, dynamical system, relay protection, etc.

Characteristics:

- High permeability – increase the accuracy of CT

- High magnetization – decrease the security factor of CT meter
- Excellent cost performance - lighter weight, smaller volume.
- Good temperature stability - long time stable working ablity at temperatures from -55 ℃ to 130 ℃

Application Area:

Nano-crystalline cores are getting more widely used in the 0.2，0.2s, 0.1 accuracy grade current transformers because of their high permeability, high magnetization and lower cost in the Iow Hc field of power supply systems, power energy measurement and control systems, dynamical system, relay protection, etc.
