The use of correlation coefficients for load identifiers and a fundamental approach towards power definitions in non-sinusoidal conditions
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 n...
