YHDC Closed type zero sequence current/leakage current transformer ZCT080 200mA/1.5mA
Introduce:
Zero Sequence Current Transformer (ZCT) is an electronic device used to measure zero sequence current in three-phase AC circuits. Its main function is to detect the zero sequence current in the circuit in order to timely detect and resolve electrical faults.
The working principle of ZCT is based on Faraday's law of electromagnetic induction. When an alternating current passes through the coil, an alternating magnetic field is generated in the coil and an alternating voltage is induced at the other end of the coil. For a zero sequence current transformer, because it only measures the zero sequence current in the circuit, it typically passes a three-phase cable through the middle of an annular iron core in order to sense the annular magnetic field.
