LSY3-10/130 three-phase integrated current transformer is suitable to be installed on the three-phase bushing of ring network switch cabinet and main column. It is used for the measurement and protection of three-phase current and zero sequence current, and can also be used for the measurement and protection of zero sequence current of multiple cables circuits.
The iron core and secondary winding of this series of current transformers are vacuum-cast with high quality epoxy resin in a flame-retardant plastic housing, which is moisture-proof, stable and maintenance-free.
