FIELD: physics.
SUBSTANCE: motor phase currents and voltages are recorder during preset time interval to decompose them into harmonic components and to measure amplitude and phase of said harmonic components. Thereafter, harmonic components incoming from circuit are filtered out. Combination of harmonic component parameters and artificial neuron circuit are used to identify technical state of object and forecast diagnosed object.
EFFECT: higher availability.
