TRANSIENT EFFECT
is defined as the result of a step change in an influence quantity on the steady state values of a circuit. [1]
In power system, transient effects can be roughly described as undesired voltages that may result in interruption or even damage not only to system devices but also to customer equipments.
Typically, they are related to the power quality issues in term of overvoltage, voltage dip and harmonics.
