  • 발행 : 1966.04.01

초록

The harmonic components of a current in the power system have been known to be harmful to the sound operation of the system. Their occurrence is mainly due to the nonlinear characteristics of magnetic materials which are used in the system. This paper has, therefore, numerically analyze the harmonics from the relation between the magnetic characteristic curve and the harmonic components of a current in the R-L-C circuit. It also has suggested a new method of calculating the magnitudes and phase angles of the harmonic components by means of approximate formulas derived here. The method is expected to apply to the determination of harmonics-limiting conditions in case of the design of such power equipments as transformer, reactor and so on.
