Wound Current Transformer – The transformers primary winding is physically connected in series with the conductor that carries the measured current flowing in the circuit. The magnitude of the secondary current is dependent on the turns ratio of the transformer.

Miniature current transformers represent a fusion of precision engineering and adaptive design, essential for modern smart grids. By overcoming integration barriers and enabling real-time monitoring in diverse applications—from renewable energy to EV infrastructure—Oswell’s innovations ensure reliability, efficiency, and scalability. As grids evolve toward decentralization and digitalization, these CTs will remain indispensable for sustainable energy management
