The LMZC-10 Phase-Sequence Through-Core Current Transformer features fully enclosed secondary windings housed within flame-retardant plastic shells. The primary bushing or cable passes through the inner hole, while the bottom is equipped with installation inserts for easy and secure fixation. Its simple and compact design makes it well-suited for measuring current, signal collection, and protective relaying in medium voltage power systems involving bushings or cables.
This transformer supports secondary current ratings of 5A or 1A, withstands power frequency voltages up to 3kV, and operates at standard frequencies of 50Hz or 60Hz. Designed for indoor installation, the LMZC-10 complies with IEC 60044-1 and IEC 61869-1 & 2 standards, ensuring reliable performance and safety.
