A current transformer is a current conversion device that converts the current in a high voltage system or a large current in a lower voltage system into a small current within the low voltage standard range. Current transformers are usually represented by three codes. The old code is represented by CT; the Chinese pinyin letter is represented by LH; and the national standard stipulates that it is represented by TA.
