Current transformer is an instrument that converts a large current at the primary side into a small current at the secondary side according to the principle of electromagnetic induction. Current transformer is composed of closed core and winding. The number of turns of its primary winding is very small, and it is connected in series in the circuit that needs to measure the current.
Therefore, it often has all the current flowing through the line. The secondary side winding has a large number of turns and is connected in series in the measuring instrument and protection circuit. When the current transformer is working, its secondary side circuit is always closed. Therefore, the impedance of the series coil of the measuring instrument and protection circuit is very small, and the working state of the current transformer is close to short circuit. The current transformer converts the large current at the primary side into the small current at the secondary side for measurement, and the secondary side shall not be open circuit.

电流互感器（Current transformer 简称CT）的作用是可以把数值较大的一次电流通过一定的变比转换为数值较小的二次电流，用来进行保护、测量等用途。如变比为400/5的电流互感器，可以把实际为400A的电流转变为5A的电流。
01.环氧树脂--浇筑技术 >> 具有密实、抗水、抗渗漏好、强度高等特点
02.加大的铁芯钢片 >> 更大的铁芯容量，多缠绕一些铜丝，提升产品性能
1. Integral pouring
Compared with the non-integrated type, the integrated pouring method has better closure, can better protect the internal line, and will not easily disintegrate .
The ability to waterproof and prevent corrosion is non-integral.
2.Shell perfusion moldingaround the wire
Machinery is related to quality stability There will be no defective products.
3.Thickness of the copper row, strong electrical conductivity
Use a thickened bronze medal touch wiring spiral Install firmly to strengthen the electrical conductivity.
