Regimes with distinctive that is, wave forms of currents and voltages in time domain and asymmetries and distortions of electrical quantities, phase coordinates. Model is suitable for relay protection of the currents and voltages, in transient machine process and its motor from disturbances and for estimation of electrical energy exploitation-operating characterist
