Special current transformer for electric energy meter

Short Description:

It is used as an electric energy metering device with high precision and small phase error requirements.The AC current input through the core hole of the transformer induces the milliampere level current signal at the secondary side, converts it into the required voltage signal through the rear end sampling resistance, and accurately transmits it to the electronic circuit based on micro processing.
