Working Principle
The operation of a compact 5A current transformer is based on electromagnetic induction. Here’s a simplified explanation of its working principle:
- Primary Winding: The primary winding of the current transformer is connected in series with the current-carrying conductor. The high current flowing through the primary winding creates a magnetic field.
- Secondary Winding: The secondary winding consists of many turns of wire wound around a magnetic core. According to Faraday’s law of electromagnetic induction, the magnetic field generated by the primary current induces a proportional current in the secondary winding.
- Current Transformation: The ratio of primary to secondary turns determines the transformation ratio. In the case of a 5A CT, the secondary current is maintained at 5A for every unit of the direct current.
- Measurement and Monitoring: The low secondary current is used for measurement, monitoring, or protection purposes. This smaller current is more manageable and can safely connect to instruments and relays.
