Nanocrystalline Cores for Current Transformers<\/h2>\n

The higher permeability of CT cores results in lower measurement errors and higher measurement accuracy. A silicon steel CT core cannot achieve sufficient measurement accuracy at low ampere-turns or smaller turns. The application of Fe-Ni permalloy cores is limited due to their low magnetization and high cost. Nanocrystalline cores are widely used for precision current transformers in power systems and energy measurement and control due to their high permeability, high magnetization, and lower cost.<\/p>\n

[\/et_pb_text][et_pb_text admin_label=”Nanocrystalline cores for current transformers are” _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n

Nanocrystalline cores for current transformers are characterized by high permeability and high saturation inductance Bs, which increases the accuracy of the current transformer, reduces the volume and improves linearity. They also offer high temperature stability in the range from -55 \u00b0C to 120 \u00b0C.<\/p>\n

Nanocrystalline Cores for Current TransformersToday’s electronics applications always require high quality in all areas. This quality must be based on reliable components. We offer an extensive range of high-quality and reliable ferrite components. With more than 40 years of experience, we supply customers from a wide range of industries worldwide. We offer our extensive range of ferrite cores in the materials BFM8 and BFM9 as well as in the high-permeability materials BFM2k, BFM3k, BFM6k BFM10k and BFM11k. Nanocrystalline Cores for Current Transformers The higher permeability of CT cores results in lower measurement errors and higher measurement accuracy. A silicon steel CT core cannot achieve sufficient measurement accuracy at low ampere-turns or smaller turns. The application of Fe-Ni permalloy cores is limited due to their low magnetization and high cost. Nanocrystalline cores are widely used for precision current transformers in power systems and energy measurement and control due to their high permeability, high magnetization, and lower cost.Nanocrystalline cores for current transformers are characterized by high permeability and high saturation inductance Bs, which increases the accuracy of the current transformer, reduces the volume and improves linearity. They also offer high temperature stability in the range from -55 \u00b0C to 120 \u00b0C.
