Current Transformer for Energy Meters High-precision, low-power consumption, epoxy-encapsulated. Provides accurate current measurement, good linearity and anti-interference. Specially designed for electric energy meters and metering equipment. 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.
