Description
Summary:The performance of electrical energy meters in non-sinusoidal conditions has been discussed since the early twentieth century and as of yet has not reached a fully comprehensive standardization. Within this context, this paper aims to update the present understanding on the subject through a closer look at the power definitions established by the IEEE Std. 1459-2010. The paper concentrates its goals across two different approaches. The first deals with the analytical development in the time domain, aiming at the decomposition of the instantaneous power in its different elementary components. The second, in turn, deals with the development of several calibration tests in different active electrical energy meters considering different voltage and current waveforms. The results show that the measurement deviations in non-sinusoidal conditions may be greater than 30% in some practical cases, which reinforces the need for more specific standards concerning the subject.
