Teaching contents
- 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 air, SF6 and vacuum
- Types of switchgear: earthing switches, disconnectors and circuit breakers
- Design and working principles of earthing switches and disconnectors in air and SF6
- Design and working principles of circuit breakers: vacuum breakers, pressured air 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
- Future developments: Intelligent control of switchgear, static switches, superconducting switchgear
