Model: NR Series

Introduce:
It is well known that the higher CT core permeability, the lower measurement error & higher measurement accuracy. The silicon steel CT core can't get enough measurement accuracy under the situation of low Ampere-tums or small turn ratios. And the Fe-Ni Perm-alloy core's application is limited because of their low magnetization and high cost. Nano-crystalline cores are getting wider usage for the 0.2，0.2s, 0.1 accuracy grade precious current transformers because of its high permeability, high magnetization and lower cost in Iow Hc field of power supply systems, power energy measurement and controlling systems, dynamical system, relay protection, etc.

- High permeability—Increase CT's accuracy level.
- High magnetization—Decrease CT meters security factor
- Excellent cost performance—lighter weight, smaller volume.
- Good temperature stability—Keep stable from-55C to 13CC for long time.
