What is Current Transformer Principles and Types about?

Current transformers (CTs) work on the principle of variable flux to transform high primary currents to lower secondary currents while maintaining phase proportionality. However, some primary current is used to magnetize the core, introducing errors. CTs are specified by their rated primary current, secondary current, burden, and accuracy limits. Specialized CTs include summation CTs, which sum currents from multiple feeders, core balance CTs for earth fault protection, and interposing CTs for applications
