Having a four-fold boost in grid inductance, the magtudes from the 5th and 7th existing harmonics decreased by 25 and 27 , respectively. A comnitudes of your 5th and 7th existing harmonic magnitudes, obtained by expression (five) and parison of your 5th and 7th present harmonics decreased by 25 and 27 , respectively. A comparison with the 5th and 7th existing harmonic magnitudes, obtained by expression (5) measured for the duration of the experiment devoid of additional grid inductances, showed that for and measured through the experiment without the need of added grid inductances, showed that the 5th harmonic, the relative error was 38 , and for the 7th harmonic, 54 . The relative for the 5th harmonic, the relative error was 38 , and for the 7th harmonic, 54 .

Existing Harmonics of Nonlinear Load When Filter Is Connected 4.1. Present Harmonics of Nonlinear Load When Filter Is Connected A crucial condition for figuring out the parameters of a nonlinear electrical load An essential situation for determining the parameters of a nonlinear electrical load will be the constancy with the generated harmonic currents ahead of and soon after connecting passive will be the constancy of the generated harmonic currents before and after connecting aapassive harmonic filter in parallel with the load. To prove this, experimental research have been carried harmonic filter in parallel together with the load. To prove this, experimental research were carried out out on a laboratory test bench. The existing harmonic magnitudes of various types of nonlaboratory test bench. The current harmonic magnitudes of various varieties of linear load were measured just before and right after connecting a passive filter. The parameters of nonlinear load were measured before and right after connecting a passive filter. The parameters from the passive filter are presented inTable 2. As an example, Figure eight shows the waveforms the passive filter are presented in Table 2. As an example, shows the waveforms and harmonic spectrum of UR currents ahead of and immediately after connecting the 5th harmonic filter and harmonic spectrum of UR currents before and soon after connecting the 5th harmonic filter with more grid inductance L11.. with additional grid inductance L(a)(b)Figure eight.
