摘要：

It is shown that currently used apparent power definitions, namely the Arithmetic VA, SA and the Vector VA, S-V, both lack an important property: The system power losses are not a linear function of the apparent power squared, S-A(2), Or S-V(2). The only apparent power definition known today, that holds this property for all the possible situations - balanced, unbalanced, sinusoidal or nonsinusoidal - has the mathematical expression suggested by F. Buchholz and explained by W. Goodhue. This paper gives a set of basic examples meant to emphasize the merit of Buchholz-Goodhue approach.
