Working Principle
The current transformer is based on the principle of electromagnetic induction and consists of a closed core and winding. The primary winding has few turns and is strung in the line of the current to be measured, while the secondary winding has more turns and is strung in the measuring instrument and protection circuit.
The secondary winding has more turns and is connected to the measuring instrument and protection circuit.
