1) The biggest function of the current transformer is to adjust the current size. In reality, the output current values ​​of most electrical equipment and transmission lines are very large, but the current value that the instrument used to measure the current can withstand is relatively small. Therefore, in order not to damage the measuring instrument, a current transformer is generally use to convert a large current into a small current, which can also better play the role of the measuring instrument in monitoring the current.

2) The current transformer can also provide insulation protection for the instrument operator to prevent high voltage from harming the human body. The protection of the current sensor for personnel is achieve by isolating the measuring personnel from the high voltage in the circuit, which is very necessary for electrical control accessories.
