The Development of 6kV~35kV HV Energy Meter Test Bench
This paper introduced a high voltage energy meter test bench, which can effectively carry out verification and calibration work on 6kV~35kV, 10A~1000A direct access type high voltage power meters and metering tanks. This bench based on direct digital signal synthesis technology and intelligent power amplification technology. The voltage boosters and current boosters generated three-phase high voltage high current signals. The high voltage isolation integrated transformer and three-phase standard watt meter used to obtain the standard electric energy pulse signal. The measurement error calculator can calculate high-voltage electric energy meter error. The high voltage electric energy test bench has the advantages of simple operation and friendly interface. The comparison between the calibration results from the high voltage power standard in National Institute of metrology and the test results from this test bench showed that the test bench met the design requirements.
