  • Abstract
    Summary form only given. Compared with traditional current transformers (CTs), electronic current transformers (ECTs) are characterized by small volume, light weight, good isolation, good linearity, and easy digitization. Hence, ECTs are one of the primary devices for signal digitization for supervising intelligent substations. We design a coreless ECT using Hall sensors as well as its mechanism and circuit configuration in order to replace traditional CTs and other CTs. The proposed ECT achieves accuracy Class 0.5 for measuring CTs and accuracy Class 5P21 for protective CTs according to IEC Standard 60044-8.
