The LXDC-10 Zero-Sequence Current Transformer is designed to interface with signaling and protective relaying equipment, detecting zero-sequence grounding currents in power systems. It acts as an essential component for protective and monitoring functions, helping to safeguard electrical networks. The transformer features a sturdy stainless steel metal shell and a compact structure, enabling easy installation while saving space.
With high accuracy across multiple specifications, this zero-sequence CT is suitable for various power system grounding applications such as neutral grounding, high-current grounding, low-current grounding, and arc suppression coil grounding. It supports secondary currents of 5A or 1A, withstands a power frequency voltage of 3kV, operates at 50Hz or 60Hz, and complies with IEC 60044-1 and IEC 61869-1 & 2 standards for indoor use.
