They commonly impact commercial, automotive, and military, electrical systems and equipment, and are often transmitted by power and data lines. What are Electrical Transients?

What causes power system transients?

Power system transients can be caused by faults, switching operations, lightning strokes or load variations. The importance of their study is mainly due to the effects the disturbances can have on the system performance or the failures they can cause to power equipment.

Can a power system be stable under a transient disturbance?

However, a system that is stable under steady-state conditions is not necessarily stable when subjected to a transient disturbance. Transient stability means the ability of a power system to experience a sudden change in generation, load, or system characteristics without a prolonged loss of synchronism.

Why are electrical transients important?

Most electrical transients are not of large magnitude but are still critical because of their effect on the performance of circuits and interrupting or protective devices. Transients in power systems follow the path of least resistance to the ground and may heat up circuit components and semiconductor devices causing malfunction and failure.

How does a transient affect a conductor?

The effect is through electrical or magnetic coupling mechanisms by the source conductor, which is carrying the transient, and the victim conductor being affected by the transients of the source conductor and through conductive and radiated coupling into a unrelated system from a “noisy” source system.
