Zero Sequence Split Core Current Transformer Single Phase Base Assemble

Ring transformer LJ-65 Zero sequence base assemble transformer Application This type of residual current mutual inductance used in neutral point insulation system of single-phase grounding protection. This series transformer with DD11/60 type relay. System normal operation, the three phase current and is equal to zero, the transformer secondary output; When a line of single-phase earth fault occurs, an increase of residual current, residual current transformer secondary
