“…The relations (4), (5), (10), (11), and (12) suggest that all the quantities P, P rms , S, Q, and PF can be obtained by processing only the instantaneous power p(t), avoiding the measurement of the rms values of the voltage and current. The simplification in the processing is not the only advantage; other more important advantages will be evidenced in this manuscript.…”

“…Their definitions under nonsinusoidal conditions are still a matter of debate, and different approaches have been proposed with the aim of identifying new quantities able to exhaustively describe the properties of the power [1][2][3][4][5][6][7][8][9][10][11][12][13][14]16,17]. Most of the formulated theories were based on a particular type of reactive energy compensation, which has influenced the definitions.…”

“…This manuscript is placed in the complex and extensive field concerning the representation of power behavior in electric systems under non-sinusoidal conditions. Many authors have investigated and debated this topic, proposing different definitions for power quantities [1][2][3][4][5][6][7][8][9][10][11][12]. This work can be considered a small contribution to this field.…”

“…Some electronic wattmeters use an analog multiplier, such as the TDM (Time-Division Multiplier) or that based on the Hall effect ( Figure 5). Modern digital power meters sample both voltage ( ) and current ( ) signals and calculate the power by processing the samples in the time domain [19,20]. The quadratic integration of the sample values of voltage and current gives the RMS values for voltage and current .…”

The significant advances in power electronics have permitted the implementation of sophisticated methods for control of electric motors. Each innovative electrical apparatus for industrial and automotive application must be correctly and exhaustively tested, both during the developing process and finally for the compliance test. The development of a new electrical system should be associated with a parallel design of an ad hoc measurement system, whose performance should be defined according to the features of the system under test. In recent years, the increasing interest for sensorless electric motor drives involved the development and implementation of a wide set of control techniques. This paper reviews the state and the trends of measurement techniques and instruments applied for the experimental characterization of variable speed drives.

“…In fact, even if the measurement of the reactive power is required for checking the supply conditions for both the producers and the consumers of electric energy, its definition is not univocal yet [1,2]. The measurement of both electric power and energy is today a still open research problem in the metrology community.…”

The measurement of both electric power and energy, especially in non sinusoidal conditions, is today a still open research problem in the metrology community. Harmonic distortion, noise, transients, over-voltages and voltage dips have increased the difficulty in achieving accurate measurements. Besides, many of non-active power component definitions that have been proposed cannot be implemented in the traditional electro-mechanical or solidstate meters. This paper goes on to investigate about the possibility to process the instantaneous power signal when harmonics are likely to occur. The intent is not to resolve theoretical controversies, but instead to investigate about the possibility to easily process the instantaneous power signal in order to reduce the meter cost.Specifically, in the paper the measurement of a power parameter A*, which is sensible to the harmonic interferences with the fundamental component of the instantaneous power, is proposed. This parameter can be adopted for the development of a simplified single-phase electric energy meter able to operate in non sinusoidal conditions and to supply distortion information. Additionally, some simulation results are proposed, to confirm the applicability of the proposed measurement technique.
