The aim of the subject is the introduction of metrological system and testing procedures in the field of high voltage techniques. It brings overview of modern diagnostic methods that are applied in electrical power systems. The subject opens questions in evaluation and interpretation of test results from the application of diagnostic methods and high-voltage tests.


Requirements to obtain the assessment are exercises attendance and a term thesis elaborating.

Successful exam passing is determined in the Study and Examination Code of CTU in Prague.
