Research for Calibration Technology of Digital Input Electric Energy Meter
As China is developing smart grid with great strength,more and more digital substations will be built,therefore,it is time for thinking of the accuracy of metering devices. But the digital input electric energy meter is different on signal transmission with traditional meter,requiring a new calibration method. By sampling analog power standard output,we bring in a special power standard according to IEC61850. Based on the special power standard,this article introduces a new calibration technology,including equipment design,error correction and value-traceability.
