Abstract

Accurate measurement of DC current is very important for safe and stable operation of HVDC transmis-sion project. Considering the mainstream high voltage DC current transformer and the national standard

this studyproposed a design scheme of steady-state error calibration system for DC current measurement device

and built anerror calibration system. Experiment and comparison were performed

and the validity of the present steady-state er-ror calibration system for DC current transformer was proved. It is concluded that this system meets the requirementsof practical application.
