Nano Crystalline Current Transformer Cores For Power Use

Nano Crystalline Current Transformer (CT) cores are made from a unique material consisting of a fine crystalline structure, engineered at the nanometer scale. This material exhibits exceptional magnetic properties, leading to improved performance in current transformers used for power measurement and protection. Nano crystalline cores provide high accuracy and efficiency, with low core losses, making them ideal for advanced power applications in electrical systems. They offer high saturation flux density, low coercivity, and excellent linearity, which allows for precise measurement of electrical currents in high-voltage power grids and other industrial systems.

It is well known that the higher CT core permeability, the lower mensurement 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 Cores 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 mensurement and controlling systems, etc.
