LSY type three-phase integrated current transformer is suitable for installation on the three-phase bushing of the ring network switchgear and the switch on the main column. It is used for the measurement and protection of three-phase current and zero-sequence current, and can also be used for multiple cable circuits Measurement and protection of zero sequence current.
