LSY19-10/150 Three-Phase Integrated Current Transformer

LSY19-10/150 three-phase integrated current transformer, featuring a phase spacing of 150mm. The internal bore is rectangular, measuring 87mm x 20mm.

The LSY type three-phase integrated current transformer is suitable for installation on the three-phase bushings of ring main switch cabinets and pole-mounted switch cabinets. It is used for measuring and protecting three-phase currents and zero-sequence currents, and can also be used for measuring and protecting zero-sequence currents in multi-cable circuits.

The core and secondary winding of this series of three-phase integrated current transformers are vacuum impregnated with high-quality epoxy resin in a flame-retardant plastic housing, which is moisture-proof, stable in performance, and requires no maintenance.

Based on different current ratios, accuracy levels, and rated loads, this series of current transformers is divided into the following types. Specific parameters can be found in the corresponding parameter tables for each model. (Note: Customized series of current transformers with different specifications and parameters can be made upon customer request.)

Rated current ratio, accuracy grade, and rated load are as shown in the table below; rated secondary current is 5A or 1A.
