- Abstract:
- Based on the electromagnetic properties of nanocrystalline alloys, such as high relative magnetic permeability, low coercive force and low hysteresis losses, in this paper are presented some considerations about the application of these materials in toroidal cores used as current transformers. Also, are discussed how the ferromagnetic core characteristics affect the current transformer performance. From the experimental results, it can be concluded that the use of nanocrystalline alloys in the current transformer cores can contribute to the reduction of phase errors, improving thus the accuracy class.
