M.Ing. / Along with the increased use of power-electronic devices, there has been an increase in the magnitudes of distorted currents. Much of the power-theory in use today was devised many decades ago, mostly for AC-systems with clean sinusoidal voltages and currents. Modem loads are more often no longer mostly linear. Against the background of a study in the basic mathematics underlying AC power theory, a few techniques concerned with per-frequency power were examined. In addition certain concerns surrounding the use of correlation indexes for the purposes of load identification were also examined.
