Abstract :
Smart substation or digital substation has become a trend of development. The Ethernet digital quantity input digital meter has become an important electric energy metering device in the digital substation by using of electronic voltage current transformer. In this paper, the smart substation related key technologies and the digital measurement system and its calibration method was researched, and the calibration system architecture be designed, which make it accurate and convenient to realize digital measurement system calibration.
