CURRENT TRANSFORMER
□ Zero -Sequence Current transformer
Match with signal equipment and protective relaying equipment when
power system produce zero sequence earthing current,act the
equipment components to realize protective or monitoring function.
It adopts stainless steel metal shell and easy installation save much
room,many specs' high accuracy zero sequence CT are power
system（such as neutral earthing， big current earthing,small current
earthing or arc suppression coil earthing）etc
