What is wrong with the conservative power theory (CPT)

Publication Date



The Conservative Power Theory (CPT) is one of the latest approaches to definitions of powers and compensation in systems with nonsinusoidal voltages and currents. It is shown in this paper that the CPT misinterprets power phenomena in electrical systems, however, and it does not create right fundamentals for the power factor improvement by reactive compensation. In particular, capacitive compensation of the "reactive energy" W, as defined in the CPT, can even degrade the power factor. It is also demonstrated in the paper that the unbalanced current in the CPT is wrongly defined.
