Considerations on the Reactive Power in Nonsinusoidal Situations

This paper discusses the strong and weak points of the time-domain and frequency-domain approaches to the energy transmission investigations in nonsinusoidal systems. The comprehension of possibilities relevant to these approaches is fundamental for the metrological tasks in nonsinusoidal systems formulation. It was shown, that despite a more complex instrumentation, the frequency-domain approach provides a theoretical basis not only for a conspicuous physical elucidation of the energy transmission decreased efficiency, but also for power-factor improvement in situations where the time-domain approach proves ineffective.
