LJK φ 80~φ 200 Zero Sequence Current Transformer ZERO SEQUENCE CURRENT TRANSFORMER

This series of current transformers is suitable for small grounding current systems indoors, with a rated frequency of 50Hz or 60Hz and a rated voltage of 35kV and below, for three-phase cable grounding protection. It can also be used in conjunction with relays

This series of current transformers is suitable for indoor use in small grounding current systems with a rated frequency of 50Hz or 60Hz and a rated voltage of 35kV and below, for three-phase cable grounding protection. It can also be used in conjunction with relays.
During installation, the transformer can be divided into two halves and then merged into one. It can be clamped tightly with a clamp and installed without power interruption.

This series of current transformers is used in indoor small ground current systems with rated frequency 50Hz or 60Hz and rated voltage up to and including 35kV for three-phase cable grounding protection, it also can be used with relay.
The transformer can be divided into two parts during installation, and then they can be combined again and buckled tightly with clamp. It can be installed without power off.
