Summary
ELXZ-10 electronic zero-sequence current transformer is suitable for AC power system 10kV cable line power supply equipment, used for line zero sequence current measurement and protection.  The secondary output of the transformer is a voltage signal, and since the output is a small signal, it can be directly connected to the secondary device without secondary conversion. It conforms to the technical specifications of the first and second integration of the national grid distribution equipment.

Product functions
 

● The product is based on the principle of low power small iron core, and the output signal is a voltage amount, which is proportional to the primary current.

● There is no magnetic saturation in the whole measurement range, the output is linear, and the small iron core structure can make high-precision measurement level.

● Zero-sequence current transformer can realize protection and measurement in one-to-one compatibility.

● There is no high voltage generated in the secondary open circuit, which will not cause danger to operators and equipment.

● The secondary signal is routed through the aerospace plug-in and shielded cable
