Aims & Learning Objectives:
Aims: To provide a detailed understanding of the basic concepts associated with the behaviour of high voltage plants under disturbances.
Objectives:
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.
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.
