Study on Engineering Application of Electronic Current Transformer

Electronic current transformers are vital in digital substations and smart substations.The article comparatively analyzes Rogowski coil type electronic current transformers with pure fiber optic type electronic current transformers,two leading products,in terms of theory and practical engineering application.The analysis result shows that in conditions where accuracy and stability are not quite strictly required,pure fiber optic electronic current transformers are obviously more advantageous,while the technology and process still need to be improved.
