The functions of Current transformers include the following aspects: Transforming the high voltage and high current of the primary circuit into the standard position of the secondary circuit, usually with a rated secondary voltage of 100V and a rated secondary current of 5A, standardizes the measuring instruments and protective devices, and the insulation level of the secondary equipment can be designed according to low voltage, resulting in a lightweight structure and low price. All secondary equipment can be connected with low voltage and low current control cables, making the wiring inside the screen simple and easy to install. At the same time, it is convenient for centralized processing and can achieve remote control and measurement. The secondary circuit is not limited by the primary circuit. It can use Y-shaped, △ shaped, or V-shaped connection methods, making wiring flexible and convenient. At the same time, when conducting maintenance, replacement, and adjustment tests on secondary equipment, it is not necessary to interrupt the operation of the primary system, and only appropriate changes to the secondary wiring can be achieved. Isolate the secondary equipment and personnel from the high voltage section, and ensure the safety of the equipment and personnel by grounding both the secondary side of the transformer. In AC circuits, transformers are commonly used to convert high voltage into low voltage, and large current into small current, which is then used for measurement, control, and protection. This not only increases the range of measuring instruments, facilitates instrument standardization, reduces the voltage and current of control and protection equipment, but also isolates the instruments from equipment or high-voltage circuits, ensuring the safety of instruments, equipment, and personnel.
