About Current Transformer Sensors

Current Transformer Sensors (CTs) are current-sensing devices that use transformer principles to produce a secondary signal proportional to the AC current flowing through a primary conductor. They are widely used for current measurement, energy monitoring, overload detection, protection and power-management applications.

IC-VIETNAM supplies Current Sense Transformers, Solid-Core Current Transformers, Split-Core Current Transformers, PCB-Mount Current Transformers and High-Frequency Current Transformers for power monitoring, smart meters, industrial automation, motor monitoring, power supplies, inverters, EV charging, overload detection and ground-fault detection.

Find Current Transformer Sensors by primary current, maximum current, current ratio, turns ratio, frequency range, secondary current / output, burden resistance, accuracy, inductance, DC resistance, dielectric withstand voltage, core type, aperture size, mounting type, termination style, operating temperature and manufacturer.

Traditional current transformers are primarily intended for AC or time-varying current measurement, rather than steady-state DC measurement. Depending on the design, CTs may operate at standard 50/60 Hz power frequencies or at much higher frequencies for switched-mode power applications. DigiKey's Current Sense Transformer category includes products ranging from 20 Hz–1 kHz solid-core devices to SMD transformers specified into the hundreds of kilohertz or MHz range.
