Opis:: The article presents the instantaneous voltage and current values recorded in the power-supply system of a vibratory unit directly from the power grid or through an inverter for a frequency setting of 50 Hz. The obtained measurement data was used to perform digital signal processing algorithms, calculations of effective voltages, currents, power (active, reactive, and apparent), and power factor tgφ. The results of the calculations were used to compare the two power systems examined.

Opis:: The article presents the results of selected energy parameters calculations, carried out for the recorded values of instantaneous voltages and currents in the three-phase power supply of the model vibratory unit. The parameters were the values of active and apparent power taken from the drive consisting of two electric motors supplied by the inverter for selected frequency settings and directly from the power grid. In addition, calculations of tgφ power factor values were made to evaluate the compensation of reactive power consumption in the tested power systems. Measurements and calculations lead to the conclusion that if the frequency of the inverter output voltage rises, the active and apparent power consumed by the model vibratory drive unit increases. The active and apparent power for setting the output frequency of the inverter from 50 Hz was less than the active and apparent power taken by the model vibratory unit that was powered directly from the power grid. The power factor tgφ in the power supply system was approximately 6, except one case (f = 30 Hz).
