With preliminary applying of Electronic Transformer (ET) based on IEC 61850 standards in power grid, the calibrations of tested transformers have attracted extensive research attention. This study proposes a novel Calibration System of ET (CSET) based on high-accuracy card. Data acquisition of ET and Standard Trans-former (ST) is gotten by optic Ethernet and PCI-4462 data acquisition card, respectively. Meanwhile, the synchronized sampling between ET and ST is completed on the optic/electronic pulse signal of PCI synchronization card. The signals processing and human interface are realized by Labview software. The system proposed in the study is feasible for calibrating Electronic Voltage/Current Transformers (EVT/ECT) of different voltage classes. System tests show that the precision of the system can get to 0.2°.
