| Abstract: | The article analyses the transient state of the unbalanced three-phase circuit on industial frequency and puts forward the concept that there are two direct current components with different attenuation coefficients. It also analyses. The varying law of them according to the phase at the intant the switch is closed, and points out how they affect the measurement of the power factor. |
