LRB type through type current transformerDetailed product description：

LRB type through type current transformer is used in conjunction with other equipment (such as PASS, circuit breaker outlet bushing, wall bushing, switch bushing, busbar, etc.), mainly for providing current measurement signals and protection signals.

The LRB type through type current transformer is composed of a secondary winding and a housing.
The secondary winding can also be supplied separately and used in conjunction with transformer outlet bushings or SF6 current transformers.

reference standard
GB 1208-2006 "Current Transformers"

Product Model

Main performance indicators of LRB type through type current transformer
Rated primary current: 50-12000A
Rated secondary current: 5A, or 1A
Rated capacity: 10-60VA
Measurement accuracy level of winding: 0.5, 0.5S, 0.2, 0.2S
Protection winding accuracy level: 5P, 10P, 5PR, 10PR, TPY
Electrical test
Operation and maintenance of polarity test, error test, volt ampere characteristic test, open circuit voltage test, etc
During operation, one end of the secondary winding should be grounded and not open circuited to avoid generating high voltage and endangering safety
maintenance-free

Ordering Instructions
When placing an order, please provide parameters such as rated current ratio, accuracy level, secondary load, inner and outer diameters, height, etc.
For protecting the winding, it is also necessary to provide accurate limit coefficients.
For TPY level protection windings, parameters such as working cycle, short-circuit coefficient, and accuracy retention time need to be provided.
