Specification

The LXK series open-type zero-sequence current transformer is of an openable epoxy resin cast structure. It is suitable for indoor use in systems with small grounding current, with rated frequency of 50Hz/60Hz and rated voltage of 35KV and below. It is used in conjunction with relay protection or signal devices to detect grounding faults. Its core advantage lies in its detachable installation, which does not require interruption of cable laying, and is particularly suitable for the renovation of operating lines.
