What is the actual function of the transformer core?

In order to transmit electric energy, the power system often uses AC voltage and high current circuits to send electricity to users. The role of the transformer is to reduce the AC voltage and high current proportionally to values ​​that can be directly measured by instruments, which is convenient for direct measurement by instruments, and at the same time provides power for relay protection and automatic devices. The quality of the transformer determines whether the personnel and equipment are safe, and the role of the iron core in the transformer determines its status.

The working principle of the transformer is the same as that of the transformer. Both operate on the principle of electromagnetic induction, so most of the iron cores used in transformers can be used for transformer cores. Nanhai Silicon Iron Core Manufacturing Co., Ltd. produces ring cores, C-type cores, ladder cores, rectangular cores, shear/laminated cores, EI-type cores, open-wound cores and special-shaped cores, which can be used in both transformers and transformers.

The high or low magnetic permeability of the transformer core has a great influence on the measurement accuracy of the transformer. C-type core, ring core, ladder core, rectangular core, etc. are used as winding cores. They adopt oriented cold-rolled high-quality silicon steel materials to ensure the consistency of magnetic flux direction and grain orientation of silicon steel sheets. They are used in mutual inductors and have the advantages of safety, high efficiency, low noise, low loss, strong short-circuit resistance and high pressure resistance. They have always been commonly used product components in mutual inductors.
