Abstract

Possible modes of ferroresonance in three-phase electric networks and analysis of substitution schemes where ferroresonance voltage increase is observed are considered. The most complete magnetization curve of the transformer core and the analysis of the generalized equivalent substitution scheme are presented, as a result of which more accurate formulas for determining the values of equivalent parameters of the electrical network and voltage transformer in ferroresonance mode are obtained. Factor of ferroresonance voltage increase is introduced, which determines ratio between amplitude values of transformer phase voltage and mains voltage. The method of determination of boundary conditions of steady ferroresonance voltage increase is given on the example of calculation of energy-saving three-phase double-winding voltage transformer of TMG12-250/15 grade, as an important factor of reliable operation of electric network. The results obtained can be applied to the analysis of ferroresonance in power supply systems of both low and high voltage.
