Operation principle, quantity transmission and traceability methods of heavy dc standard measurement device are described. The uncertainty evaluation of the calibration methods and the current ratio accuracy is emphasised. The aim of the study is to establish a quantity transmission and traceability system of heavy direct current. The system consists of the laboratory reference standard device whose accuracy is 0.0005%, the field transfer standard device whose accuracy is 0.02%, the field working standard device whose accuracy is 0.05% and testing, evaluation and traceability method of the value of quantity. The method covers the whole process of self‐calibration, inter‐calibration and the comparison with some other standard measurement device. The research provides a scientific approach to accurate measurement of dc energy consumption, and has broad prospects in energy‐saving and emission‐reduction.
