Abstract:
In this work is presented some considerations about the application of nanocrystalline
alloys in toroidal cores for current transformers used for measurement purposes. Based on the
electromagnetic properties of these materials, such as high relative magnetic permeability,
saturation flux density of magnetic, high resistivity and low hysteresis losses, are discussed
the ways in which these characteristics affect the performance of the current transformer.
From these results, it can be concluded that the use of nanocrystalline alloys in the cores of
these devices can contribute to the reduction of phase errors, improving thus the accuracy
class.
