About the Rejection of Poynting Vector in Power Systems Analysis

Print

Alexander E. Emanuel

This article is a response to a paper presented at the sixth International Workshop on Power Definitions, a report that rejected the fact that the Poynting vector (PV) provides useful information “for academic interpretation of power properties and for practical applications of power theory”. This study explains how the PV reveals the existance of power oscillations unexplained by simple mathematical models used in the basic circuit theory.

It sheds light on the puzzling situation where the  PV exists but does not  transfer energy and also presents some examples that reinforce the usefulness of PV as a fine tool in understanding the flow and the components of electromagnetic energy.
