Summary

This subject is consolidating the knowledges obtained in previous studies (Electrical Apparatus 1, Electrical Apparatus 2, electromagnetical Apparatus, Plasma Technics).Students acquire basic experiences in designer work on design and development of new apparatus in the general form. The course is intent on design of low voltage switching apparatus (contactors, protectors) up to extra high voltage switching devices (extra high voltage circuit breakers, disconnecting switches) and of other elements used in switching stations and switchboards. The numerical methods of solution of physical fields are used for design works.
