THREE-PHASE INTEGRATED
CURRENT TRANSFORMER SERIES
The LSY type three-phase integrated current transformer is suitable for installation on the three-phase bushing of RMU and pole mounted switches, used for measuring and protecting three-phase current and zero sequence current, and can also be used for measuring and protecting zero sequence current of multiple cable circuits.
The core and secondary winding of this series of three-phase integrated current transformer are vacuum casted with high-quality epoxy resin in a flame-retardant plastic shell, which is moisture-proof, stable and maintenance-free.
According to the different current ratio, accuracy level and rated load, this series of current transformer is divided into the following types, the specific parameters are detailed in the corresponding parameter table for each model.
(Note: can be customized according to the user's requirements of different specifications and parameters of the series of current transformer)
| Rated primary current (A) | Rated secondary current (A) | Accuracy Class And Rated Load(VA) | Accuracy Class And Rated Load(VA) | Composite accuracy class and rated load(VA) |
