Teaching content This lecture covers the basic designs of high voltage substations as well as the design and working principles of high voltage switchgear:
  • Switching processes and stresses induced by switching
  • Arc behaviour in different media: air, SF6, vacuum, natural originated gases, new insulating gases
  • Types of switchgear: earthing switches, disconnectors and circuit breakers
  • Design and working principles of air insulated and gas insulated earthing switches and disconnectors
  • Design and working principles of circuit breakers in different isolating media: vacuum breakers, pressured air, Fluoronitrile and SF6 breakers (thermal blast and self-blast chambers)
  • Stresses on earthing switches and disconnectors in the event of short circuit
  • Testing of switchgear
  • Reliability of switchgear and typical monitoring systems
  • • Future developments: Intelligent control of switchgear, static switches, superconducting switchgear, HVDC fault separation devices
Learning objectives After successful completion of the module, the students understand the purpose and working principles of high voltage switchgear as well as their usage in high voltage substations. They are able to differentiate between the switching equipment types, the equipment stresses and the testing methods. Moreover, they are able to explain advantages and disadvantages of different substation layouts taking into account the energy availability requirements and reliability of the equipment. Sustainability drives the present developments of the new equipment. The students learn the most important factors of the life cycle analysis.
