Simulation Connection of Current Transformers and Winding of Relay in B2 Spice Software Complex

The article presents the results of measuring the emission of currents of higher harmonics of modern household electrical receivers. Analysis was conducted for sine wave currents and voltages of modern household electrical receivers. The main methods for the analysis of non-sinusoidal modes are given. Theoretical decomposition of higher harmonics into Fourier Series is shown as well as the table of odd current harmonics in modern electrical equipment and lamps. The scheme of the experiment and the conclusions obtained from the analysis of the measured parameters are given.
