The circular through core current transformer is mainly used in the cable circuit environment, which has simple structure, small volume and flexible application. According to the cable specifications used in the main circuit, there are many kinds of hole diameter corresponding to the core penetration. The diameter of the pierce hole of this series of product is from 25mm to 200mm, and the current of the main circuit includes 63A ~ 2000A. The series of products can meet the technical requirements of different precision such as 0.2, 0.5 and 1. At the same time, it can also meet the strict requirements of the new national standard for the balance characteristics. The unbalanced current output value can also be better than 30mA, 10mA, 5mA, even 3mA, which greatly reduces the false alarm caused by the interference of the current and magnetic field of the main circuit, and provides sufficient guarantee for the reliability of the equipment. Excellent and advanced production process. This series of products meet the requirements of GB-14287.2-2005 and GB14287.2-2014.
