Abstract

The paper describes some problems concerning the evaluation of travelling standard drift effect and its further influence on evaluation key comparison reference value during a key comparison. The authors have demonstrated the evaluation procedure for drift effect when its model can be linear or not linear. Comparative analysis of the proposed procedure with other different approaches was done applying the electric power data of COOMET.EM-K5 key comparison. All the calculations were done in MATLAB.
