The invention relates to an intelligent
electric energy meter field test device and a test method thereof. The test device comprises a micro controller, a metering unit, a
communication interface unit, a memorizer, an input part, a current acquisition channel and a
voltage acquisition channel, a
clock module and a pulse input unit; wherein the micro controller receives a control instruction of the input part and sends out an operation
signal to the
communication interface unit, the memorizer, a displaying part and the
clock module; the metering unit carries out filtering, amplifying, sampling and
digital signal processing on analogue signals transmitted by the current acquisition channel and the
voltage acquisition channel, so as to convert the analogue signals into digital signals, and the digital signals are sent to the micro controller; the
communication interface unit carries out data communication with an
electric energy meter and downloads a user file from a
server, and the user file is uploaded to the micro controller, and data of field test is uploaded and recorded into the
server. The invention has the
advantage that whether all the functions of intelligent
electric energy meter are in normal operation or not can be determined by virtue of field test and diagnosis without interruption of power supply, modifying field primary and secondary loops or changing the state of the
relay of the electric energy meter.
