The connection mode of a current transformer used for single-phase circuit is suitable for measuring single-phase current and single-phase power and protecting single-phase grounding short circuit.
The incomplete star connection mode of two current transformers is suitable for measuring three-phase current and three-phase power and protecting short-circuit faults between phases.
The connection mode of two-phase current difference between two current transformers is suitable for measuring one-phase current and protecting short-circuit fault between phases.
The star connection mode of three current transformers is suitable for measuring current and power in three-phase four-wire system, which can protect any form of fault.
