2 TEACHING RESULTS AND THE METHODS OF ASSESSING TEACHING RESULTS Modue target The aim of the modue is to famiiarise students with the structure, the principe of operation, testing and measurement methods, the roe of transformers in an energy system, induction machines, synchronous and DC machines. Effect symbo Teaching resuts Teaching methods (/c//p/other) subject effects effects of a fied of study W_01 W_02 W_03 U_01 U_02 U_03 A student has fundamenta knowedge as regards appying the aws of eectromagnetism in the eectrica machine theory. A student has knowedge as regards the structure and principe of operation concerning: induction, synchronous, and DC machines. A student is acquainted with basic safety as we as expoitation principes (concerning eectrica machines). A student is abe to pan and conduct basic experimenta tests of eectrica machines according to OHS rues. A student is abe to make anaytica cacuations with the use of simpified substitution diagrams for basic work states of eectrica machines. A student is abe to present and interpret measurement resuts. K_01 A student can co-operate and work in a team / K_02 A student is aware of the impact of eectrica machines, which work in an energetic system, on the environment.
