The main goal is to analyze the results of such power theory definitions under nonsinusoidal and unbalanced conditions, pointing out its major advantages, possible drawbacks or relevant aspects for discussion. © 2009 IEEE.423-430engConservative power theoryHarmonic powerPower factorPower theoriesReactive powerVirtual instrumentationPower factorsPower theoryVirtual InstrumentationElectric power factorPower electronicsInstrumentsTrabalho apresentado em evento10.1109/COBEP.2009.5347670Acesso aberto2-s2.0-77949948376
