Abstract

The article analyzes the possibility of determining the load capacity of the three-phase electrical networks in non-sinusoidal and unbalanced modes. There have been presented the concepts of effective period on the supply voltage of the active, reactive and apparent power, as well as their standard deviations. It has been shown that the latter has the power fluctuations, and those, in turn, are the sum of power unbalance and harmonic distortion. It has been proposed to determine the harmonic power to use RMS difference of capacity fluctuations and unbalance. There has been shown that the power of the distortion due to the presence of harmonics canonical enough to measure the sixth harmonic frequency of the supply voltage. Formulas for determining this power with instant facilities have been offered.
