The silicon steel core of the current transformer and voltage transformer is required to detect the maximum value of the outer wall and the minimum value of the inner wall and the gap before shipment. The traditional measurement method is manual caliper detection, which is not only inefficient (about 30…

The magnetic ring and the connecting cable form an inductor, which is a commonly used anti-interference component in electronic circuits. It has a good shielding effect on high frequency noise, so it is called an absorption magnetic ring. Because it is usually made of ferrite material, it is also called…
