Key Feature

 

The structure of current transformer is composed of magnetic core, primary winding and secondary winding, shell and so on.
When the measured current flows through the primary winding, this current will excite a magnetic flux in the magnetic core, and this magnetic flux will pass through the magnetic core to the secondary winding, and excite a voltage signal in the secondary winding.
According to Ohm's law, there is a linear relationship between current and voltage, so the voltage signal is the signal of the measured current, and a more accurate current value can be obtained by amplifying the circuit.
