This seminar provides the electrical engineering fundamentals required to understand modern protection and control systems used in utility and industrial power networks. Participants will gain a comprehensive overview of the structure and operational behavior of electrical power systems, as well as the most important equipment used in energy supply networks.
-
Special emphasis is placed on the physical phenomena associated with network faults and their effects on equipment and protection systems. This creates a solid foundation for understanding the tasks, functions, and requirements of protection devices and facilitates entry into advanced protection engineering training courses.
-
Upon completion of the seminar, participants will be able to:
• Describe the structure and operation of electrical power supply networks.
• Assess typical network faults and their consequences.
• Understand and classify the main components of a power system.
• Explain the role of instrument transformers and switching devices.
• Understand the fundamentals behind the application and parameterization of protection relays.
