Transient disturbances

Definition

Transient disturbances refer to temporary, short-lived disruptions or fluctuations in a system that can cause significant changes in performance or behavior. These disturbances can arise from various sources, such as sudden changes in load, external environmental factors, or faults in electrical systems, and can impact the stability and operation of superconducting generators and motors.

5 Must Know Facts For Your Next Test
