Defining an Uncertainty Budget in Electrical Power and Energy Reference Standards Calibration

In the paper, calibration procedures for testing and examination of electrical power and energy reference standards are presented. The main focus of the work is definition and evaluation of all influencing factors that affect one calibration procedure, and which are a reason for error and uncertainty existence. Some of the influencing factors have negligible effect on the measurements, nevertheless they are about to be mentioned and mathematically evaluated. In the end, a case study with practical considerations is presented.
