The LSY three-phase integrated current transformer is suitable for installation on the three-phase bushings of the ring network switch cabinet and the switch on the main column. It is used for the measurement and protection of three-phase current and zero-sequence current. It can also be used for multi-cable circuits. Measurement and protection of zero sequence current.
The core and secondary winding of this series of zero-sequence current transformers are vacuum-cast with high-quality epoxy resin in a flame-retardant plastic shell, which is moisture-proof, has stable performance and requires no maintenance.
