Abstract
Application of the measurement uncertainty approach in expression of the measurement result of active power single-phased consumer is presented in this paper. The measurement of active power is carried out by means of electrodynamic wattmeter, which is in direct connection with the consumer. In this paper it is assumed that the results of the active power measurement by means of electrodynamic wattmeter are quite evenly spread between the highest and the lowest values of active power, i.e. rectangular or uniform distribution of measurement results is assumed.
Keywords
