Abstract
Main results participating laboratories which are measuring the same electric active and reactive energy travelling standard of low-frequency 50/53 Hz energy in a framework of GULFMET.EM-S5 supplementary comparison of energy are presented. The paper describes some problems concerning the evaluation of travelling standard drift effect and its further influence on evaluation reference value during a comparison. Degrees of equivalence and expanded uncertainties of participants are set. Also $E_{n}$ number was calculated for each participant GULFMET.EM-S5 supplementary comparison of energy with the aim of determining data consistency.
