Laposha M. Electrical equipment efficiency increase for high-voltage insulators’ testing at permissible level of electromagnetic interference

In the thesis the actual scientific task of electrical equipment efficiency increase for high-voltage insulators testing at permissible level of electromagnetic interference has been solved by developing new mathematical models, development of the methods for electromagnetic field distribution control in the elements of corresponding test electrical equipment and conducting specialized experiments. For the first time, the mathematical model of high-frequency line trap reactor was developed, which, which allows us to provide pointed resonance adjustment of the line trap to the intended high frequency and to increase its throughput resistance substantially is up to 20 kОm and above. The method of electric field control in the inductor of high-frequency line trap, which allows us to harmonize the distribution of electric potential with the distribution of the potential induced by the coil magnetic field, as well as to reduce the negative influence of external electromagnetic fields. The interdependencies of linear dimensions of the insulator’s steel core conical part profiling are proposed for the first time, which allows reducing of the local values of the electric field strength and the insulator’s electromagnetic interference level.
