Power quality monitoring is a means of power quality monitoring in power systems, and the safe operation of power supplies for power quality monitoring is very important. In the paper, a calibrator based on power quality monitoring terminal detection is introduced.  Based on FPGA minimum system circuit, the design integrates the idea of modularization and realizes the analog output of the calibrator through exclusive high-precision linear power amplifier. Power quality calibrator is a vital tool for power quality monitoring terminal. The calibrator can complete all power quality monitoring through open interface program, automatic test software and platform cooperation.
