The utility model provides a verifier configured in split structure. A high voltage region comprises an A-B phase collector for acquiring A-B line voltage values and A-phase current values in real time, and a C-B phase collector for acquiring C-B line voltage values and C-phase current values in real time. The A-B line voltage values, the A-phase current values, the C-B line voltage values, and the C-phase current values are converted into wireless signals through wireless transmitters and are transmitted to a wireless receiver in a low voltage region. A power value and an electric energy value are acquired by demodulating information of voltage values and current values by the wireless receiver and calculating the same by a digital signal processor. A processor compares the power value and the electric energy value with a power value and an electric energy value which are converted from a received electric energy pulse signal of an electric energy metering device in order to acquire a comparison result. Therefore, a purpose of verifying the global error of the electric energy metering device is achieved. Itemized verification is prevented so that testing steps are decreased while working strength is reduced.
