The Design and Implementation of Electronic Transformer Calibration Device Based on Virtual Instrument Technology

Electronic Transformer and other smart sensor is one of the key technologies for the construction of smart grid,and the development of smart grid is inseparable from the development of smart measurement,metering and monitoring technology for electronic transformer.To ensure the safe operation of power systems and the justice of energy metering and trade settlement,we researched the electronic transformer error checking device with independent intellectual property rights;designed and built electronic transformer intelligent verification platform with the integrated design and virtual instrument technology together,which could support multi-mode(analog,digital electronic,optical digital and Ethernet,etc) input signals,with the physical range adaptive function of input signal and acquisition system,multiple correction factor input and reports produce automatically.It drives the calibration operation effectively in the digital substation,and achieves the full coverage of measurement.
