Lots of things around nonsinusoidal conditions, fundamental frequency, method, conditions, reactive power, factor, power measurement, frequency response, power quality, voltages, fundamental voltage, fourier series, power measurement techniques, fourier transform, instrument, discrete fourier transform, values, non sinusoidal situations, and power measurement are described inside this dissertation. The dissertation gives you information about metering methods, zero crossing, currents, sinusoidal signals, power analysers, angle, harmonic current, harmonic power, voltage, system impedance, sampling rate, power system, power analyser, active harmonic power, apparent power, non sinusoidal conditions, measurement techniques, reactive power measurements, and power.

In this dissertation we can read info regarding measurements, electrical power, phase angle, components, calibration system, definitions, frequency, impedance, active power, equation, range, signal, calibration, harmonic voltage, frequency domain, fourier, meters, power components, and voltage harmonics. These are some excerpt from this dissertation:

Some AC quantities, as the reactive power, are not properly defined for nonsinusoidal situations. Efforts are made in this work to understand and explain the problems of extending the reactive power definition to cover nonsinusoidal conditions. The main conclusion is that reactive power is used to obtain information on more than one property of the power transmission mechanism, e. g. phase angle, transmission efficiency and line voltage drop. No single power definition can alone provide information on all these properties in a non-sinusoidal situation. Moreover, instrument designs may not comply with any of the extended definitions and these meters exhibit extra errors due to this non-compliance for non-sinusoidal conditions.

In addition, the dissertation presents info regarding signals, power, sampling, system, fundamental harmonic, current harmonics, sinusoidal signal, calculation algorithms, power measurements, digital sampling, source impedance, amplitude, current, power factor, apparent, discrete integration method, measurement, harmonic, and value.
