The dissertation is devoted solution to an actual problem - the developments and improvements of methods analysis of internal overvoltages in electrical networks with isolated neutral, their mathematical modeling and studies to develop recommendations to improve the efficiency and reliability of functioning of the electrical power system. In the work presented improved mathematical model for the research of electromagnetic processes in electrical networks, substantiated the role of interference in the processes of vibrational states of energy exchange between them, obtained the exact expression dissipative function the Rayleigh of electromagnetic oscillations in the circles in the approaching linear of Ohm's law, when resistance force the free harmonic movement of charge in the area range of active resistance proportional to velocity of charge transport through it. The demonstrated appropriateness of limiting deep overvoltages arresters using of nonlinear terminators of overstrain, and limiting overvoltages must be determined for each individual network on the basis of a detailed study of overvoltages in it and in view of measures to limit overvoltages in the network, proposed repayment ferorezonansnyh phenomena in electrical networks plugging active resistance in disconnected triangle voltage transformer.
