Electrical and Electronic Engineering
A transient system is a short-lived oscillation in a system caused by a sudden change of voltage, current, or load. Engineers use voltage regulators and surge suppressors to prevent transients in electricity from affecting delicate equipment.

International standards define the magnitude and methods used to apply them. Typically refer to EN-61000-4-4, the European standard for Fast Transient testing.
