This paper introduces a new generation multi-meter three-phase direct electric energy meter inspection device that can meet the R46 international standard.The inspection device is mainly composed of signal source,linear power amplifier,three-phase standard electric energy meter,error calculator,through-center isolated current transformer,Bluetooth communication converter and so on.It can carry out compatibility tests on the 2013 version of smart electric energy meter,2020 version of smart electric energy meter and smart IoT electric energy meter,and complete routine test items such as basic error,latent start,electric energy meter constant,electric energy representation value error,timing accuracy,etc.At the same time,it can also meet the requirements of the new test items of the R46 international standard such as the accuracy of harmonic electric en-ergy and the accuracy of harmonic measurement.The test results show that the device can work stably and reliably when detec-ting 32 direct electric energy meters at the same time,and the technical indexes meet the design requirements.
