- TITLE: MEASUREMENT UNCERTAINTY OF TEST STATION FOR MEASUREMENT OF ENERGY EFFICIENCY OF ELECTRICAL MACHINES
- ABSTRACT: The aim of this paper is to present the method for calculation of measurement uncertainty of test station for measurement of energy efficiency of electrical machines. Energy efficiency has been measured by direct method in accordance to international standard IEC 60034-2-1. Measurement uncertainties of all electrical and mechanical quantities of influence have been used for calculation of combined and extended measurement uncertainty. The paper contains the results of measurement of energy efficiency of the induction motor, model of energy efficiency, results of calculation of measurement uncertainty, as well as a discussion of all the results presented.
