Split Core Current Transformer (CT) is a type of transformer commonly used for measuring electrical currents in power systems. It consists of two separate halves, which can be opened and closed, allowing them to be installed around existing conductors without the need for disconnecting the electrical circuit. The split core design offers ease of installation and retrofitting, making it suitable for a variety of applications such as energy monitoring, power quality analysis, and electrical load management. The UL2808 XOBA Split Core Current Transformer(CT) is likely a specific model or variant that may have unique features or specifications.
