Transient fault
From Wikipedia, the free encyclopedia
In power engineering, a transient fault is a fault that is no longer present if power is disconnected for a short time.
Faults in overhead powerlines are often transient.
For example, if a tree contacts a line momentarily, this is a transient fault.
Similarly, if an arc is created in a line due to lightning, the arc will be fed by system power, but if the power is disconnected for a short time, the arc will disappear, and power may be reconnected, and the line will operate normally.
