Product Description

Protection Transformer from Acrel Manufacturer

Product Description

Low Voltage AC 0.66kv Protection Current Transformer (CT) is used to transform the high AC current to small easily manageable values.
They are connected with the panel meter or relay and they can help to measure the current or protect the equipment.
AKH-0.66 series protective current transformers are mainly suitable for multiple busbar crossing, as relay protection, this product is developed to protect the system from short circuit or overload, with different accuracy levels and accuracy limit coefficients, and can be extended to different perforations It is widely used in low-voltage power distribution protection systems. It is mainly used in the second-phase transformation of power plants or differential protection circuits. It can be used together with relays or with our company's line protection ALP, ARD3T, etc.
           AKH-0.66 series protection current transformers generally have accuracy grades: 10P5, 10P10, 10P15,
10P20, etc., in 10P20, "10" means compound error 10%, "P" means protection, "20" accurate limit coefficient, expressed by "ALF", ALF=I1/I1n, means 20 times the rated primary current, Therefore, 10P20 means that under the condition of 20 times the rated primary current, the composite error should not exceed 10%.
