摘要
The scope here is to derive a model of the measurement error of static energy meters. The model proposed is based on three error parameters: gain, phase and bias error. The validity of the model is confirmed through the statistical analysis of the measurement results obtained during the calibration of a commercial energy meter, compliant with the Measuring Instruments Directive 2004/22/EC. The experiments also involved operating conditions of the meter beyond those required by the calibration procedure prescribed by the relevant standards. A further analysis is offered aimed at verifying the statistical significance of the parameters of the model.
