Working of current transformer
Understand the Problem
The question is asking about the operation and functionality of a current transformer, which is a device used to measure alternating current (AC) by producing a scaled-down replica of the current flowing through a conductor. Understanding its principles of operation, construction, and applications is essential for providing a comprehensive answer.
Answer
Current transformers convert high AC primary currents to smaller secondary currents for measurement, based on electromagnetic induction.
Current transformers work on the principle of electromagnetic induction. They convert high primary AC current into a smaller secondary current, using coils and an iron core. This allows safe measurement and monitoring of high currents in power systems.

More Information
Current transformers are vital in electrical systems, allowing for the monitoring and control of large current flows by reducing them to measurable levels, ensuring safety and equipment protection.
Tips
Mistakenly considering current transformers as voltage transformers due to similar terminology. Remember, current transformers are for measuring current, while potential transformers measure voltage.
