Description: or equivalent.
Aims:
To provide a detailed understanding of the basic concepts associated with the behaviour of high voltage plants under disturbances.

Learning Outcomes:
Explain why a distributed parameter model is required to describe wave behaviour under disturbances in overhead lines and underground cables; ascertain the corrective measures that should be taken to mitigate excessive transients; explain the basic operation of circuit breakers.

Skills:
Application of the information, techniques and methods detailed in the unit material, to the proposal of, and the carrying through of, appropriate solutions to engineering problems associated with transient and overvoltage phenomena in electrical power systems. Taught, facilitated and tested.

Content:
Switching transient studies: Wave propagation on a single phase line; wave propagation on multi-conductor lines. Temporary overvoltage: Causes of overvoltage; protection of system and equipment against overvoltage; insulation co-ordination. Switchgear design; Circuit breakers; circuit breaker technology; circuit breaker parameters.
