Learning outcomes of the course unit

Students will receive a survey about problems connected with diagnostics of electrical materials and devices, about principles and organization of testing in Czech Rep. Students will be acquaint with tests which are obligatory at introducing a new electrical product to market. In practise they will be able to suggest a suitable diagnostic method for solving of a concrete diagnostic problem.

Aims

The aim of the course is to acquaint students with basic concepts and methods from the field of diagnostic of electrical materials and devices, with principles and organization of testing stations in Czech Rep. Students will be familiar with electrical and mechanical tests, safety tests and tests of climatic resistance. Students will receive essential information about physical methods for evaluation of a structure and composition of observed subjects.
