This utility model discloses a green and low-carbon dual-mode measurement unit calibration device, relating to the field of power metering equipment calibration technology. By setting up a device body with multiple calibration stations, this utility model provides a physical basis for batch parallel calibration of measurement units, improving space utilization. Multiple sets of current transformers enable centralized supply and independent distribution of calibration signal sources, replacing the existing whole-machine measurement method. Centralized communication management by the communication control unit enables parallel acquisition and processing of calibration data, thus constructing an independent and dedicated batch calibration platform. This eliminates the reliance on the entire measurement switch as a calibration carrier, greatly simplifying the operation process and significantly improving calibration efficiency.
