Research and development on the basis of mathematical modeling the antiresonant potencial transformers 220 kV with opened magnetic conductors

The basic requirements to potencial transformers are stated. New designs of antiresonant potencial transformers 220 кВ with opened rod cores are offered. Methods of calculation on the basis of two-dimensional and three-dimensional field modelling by a method of final elements by means of computer programs are offered. Results of modelling the electromagnetic fields and basic scheme of the transformer made with application of programs Matlab, SimPowerSystem and Simulink are presented, allowing to spend the analysis of work, to carry out selection of parameters.
