Some Considerations Regarding Efficiency of Electrical Energy Consumption

The analyses concerning an electric consumer may consist in determination of several components of electric current, injected by this consumer, in the electric network. Regarding sequence negative and sequence zero components of electric current, the unbalanced electrical consumer is the cause of its presence. Regarding harmonic components of electric current, the non-linear consumer is the cause of its presence. The efficiency about electric energy consumption may be characterized by the values of those components; the paper describes several considerations regarding those components of electrical current and its flow.
