A current transformer is an electrical device used to measure current. It can convert high current into low current for easy measurement and control. The components of current transformer include magnetic core, winding, insulating material and shell.

It can work in harsh environments for a long time, greatly improving the stability and reliability of product devices, especially suitable for transformers and inductors in military power supplies, replacing permalloy and ferrite.

Low loss amorphous magnetic core

A CT core for an electric meter is a type of magnetic core used in a current transformer (CT). The CT core is used to concentrate the magnetic field produced by the primary current, which is the current that is being measured.

Common mode choke selection would largely depend on the EMI characteristics of your power supply. Normally, you would choose the inductance value based on the amount of EMI that you would like to attenuate.

Amorphous and ferrite cores are two types of magnetic cores used in a variety of electronic devices, such as transformers, inductors, and motors. They have different properties that make them suitable for different applications.
