A compensation of reactive loads of electric circuit branches is proposed with use of evaluation of branch inductance or capacitance. For evaluation of branch inductance or capacitance the injection of currents is used, currents are differ from the main frequency of the electric main, number of frequencies in not less than threeThereafter, currents and voltages in every branch are measured, results are averaged for every frequency and inductance or capacitance are calculated. To prevent resonance phenomena in case of higher harmonic interference a compensation capacitance is corrected. |
