Application characteristics of split core current transformer:   Split current transformer is an important equipment for electric energy metering, current measurement and microcomputer protection in power system. Generally, the primary winding of split current transformer is connected in series in the power line during use, and the secondary winding is connected with measuring instrument, microcomputer protection and automatic control device. Since the traditional split current transformer is connected in series in the equipment in the application of substation, it is directly embedded in different circuits during initial installation, and the electrical connection of substation is hard connection, so once the split current transformer needs to be repaired and replaced, it needs to be disassembled from the connection point, which is very inconvenient to maintain. However, the open split current transformer can be installed and disassembled with power on, which is simple to install and maintain. Therefore, the open split current transformer will be a development direction of current measurement technology. Due to the special structure of the open split current transformer, it needs to be distinguished from the traditional electromagnetic split current transformer in terms of main materials, process, structure, etc. during design.   This series of split-type current transformers are designed for electrical installations that do not require disassembly or disconnection of existing main busbars or cables. The split core design does not require disconnection of the busbar, making it easy to open and close, easy to install, and beautiful in appearance.   1.
