How U Current Transformers Work in Electrical Systems
Principle of OperationU current transformers (CTs) operate based on electromagnetic induction, converting high currents from a primary conductor into proportional, manageable currents for measurement and monitoring. These transformers feature a U-shaped magnetic core that encloses the conductor carrying the current to be measured. Hewei’s U current transformers are engineered to ensure high accuracy by reducing core losses and maintaining linearity under varying load conditions. The induced current in the secondary winding is directly proportional to the primary current, making them suitable for applications such as power metering, protection systems, and energy monitoring. Applications in Electrical SystemsHewei’s U current transformers are indispensable in electrical systems requiring precision and reliability. In power […]
