Digital electric energy meter checking device with actual loading checking

The invention discloses a digital electric energy meter checking device with actual loading checking, comprising an electric energy meter check gauge and a control computer connected with the electric energy meter check gauge. The digital electric energy meter checking device is characterized in that a merging unit corresponding to a digital electric energy meter is connected with the electric energy meter check gauge by optical fiber Ethernet, and a pulse output terminal of the digital electric energy meter is connected with a pulse input terminal of the check gauge by a twisted-pair cable. The digital electric energy meter checking device simultaneously couples real time IEC61850-9-1 message of the merging unit and pulse signals of the electric energy meter into the electric energy meter check gauge to be compared with each other, so that the actual loading checking of the digital electric energy meter can be realized.
