Course detail
Diagnostics in Electricity Industry
FEKT-MKC-DELAcad. year: 2024/2025
Content of the course covers basics of diagnostics in consequence of faults progress and symptoms and in context of the faults causes seeking and their relationships. Chosen diagnostics methods used for apparatus condition determination, level of failure assessment and faults location using analysis of electrical and non-electrical quantities are discussed.
The course is aimed to vibro-diagnostics, noise-diagnostics, infra-diagnostics, and some electro-diagnostic methods oriented to diagnostics of chosen electrical apparatus and to electro-insulating systems in general. There are taken into consideration fundamentals of progress and detection of faults, measurement and test systems, including signal analysis and evaluation procedures as a part of all mentioned diagnostic methods. Attention is also focused to subsequent utilization of diagnostic data for complex diagnostic systems of technological entities.

Rules for evaluation and completion of the course
Overall classification of the course is in compliance with the FEEC rules. Requirements for completion of the course are specified by a regulation issued by the lecturer responsible of the course and are updated for every year.
The final exam is aimed at understanding in the field of power engineering apparatus diagnostics using vibro-, infra-, noise-diagnostics and chosen electro-diagnostics methods.
The content and forms of course units are specified by a regulation issued by the responsible lecturer and are updated for every academic year. In general, the presence at class is optional except laboratory training, which is mandatory. Missed laboratory training can be accomplished within semester in an alternative date in justified cases, whereas regular letter of apology and agreement with the teacher is required.
