Current Transformers (CT) - Instrument Transformers

---

Current transformers, abbreviated as CT, are specialized transformers used in AC electrical circuits. Together with voltage transformers (VT), they are collectively known as "instrument transformers." Current transformers function by transforming higher current (I1) on their primary side into lower current (I2) on their secondary side, maintaining a specific ratio. Typically, the secondary current is transformed into 5A or 1A, as prescribed by current IEC and IEEE regulations. The transformed current can be easily and safely measured, serving the purpose of monitoring and measuring electricity consumption in circuits and systems. Current transformers can also play a crucial role in providing protection to the primary side electrical circuits.
