- Prerequisite:
- Introduction to Electrical Engineering (12UE)
- Lecturer:
- Tutor:
- Supervisor:
- Department of Electroenergetics
- Synopsis:
-
The subject describes the power engineering as a part of the state economy and explains the power engineering in connection with environment. It explains principles of electric strength of insulation systems and describes some electric phenomena which may be dangerous to insulation systems. It shows the way of protection of insulation systems
