Summary
This subject should give the students of 4th year of the magister degree of the university education the comprehensive knowledge of transient effects on electrical machines and apparatus. In practices the students learn to create and to applicate equivalent diagrams of switches, lines, various types of loads etc. for the solution of the transient effects by means of the EMTP - ATP software. New methods of the transient effects modelling increase the effectiveness of the solution of practical engineering problems.
