THT-LJK Zero Sequence Current Transformer

The zero-sequence current transformers(cables types) with the diameter of 80-300 include various high-precision zero-sequence current transformers different in capacity , ratio and accuracy limit factor, as well as other high-precision zero-sequence current transformers matching with small current grounding line selection devixes and relays, which can be classified as integral types and modular- based products.

The CTs adopt the shells of engineering plastics, and are completely enclosed with resin cast , featuring good looks, easy installation space and a variety of specifications, able to meet the needs of various protection devices and various modes of power system operation (neutral grounding , no neutral grounding , high resistance grounding , low resistance grounding and arc-suppression coil grounding).
