An overvoltage is a voltage that exceeds the maximum value of operating voltage in an electric circuit. Pulse overvoltages, their formation and division .Pulse overvoltages ares short-term overvoltages, lasting from a couple of nanoseconds up toma couple of milliseconds. It is one of the most noticeable and most harmful manifestations of electromagnetic interference perturbing influences and it poses a threat, especially to electronic equipment containing semiconductor components. Depending on its origin, a pulse overvoltage is classified into the following categories:atmospheric overvoltages. Lighting ElektroMagnetic Pulse
switching overvoltages Switching ElektroMagnetic Pulse,overvoltages formed during discharges of static electricity, ElektroStatic Discharge, overvoltages due to nuclear explosions,Nuclear ElektroMagnetic Pulse
Atmospheric overvoltages They are the most dangerous, and are induced primarily by thunders.

Rise in the voltage above acceptable limits. Depending on the level of the over-voltage, the damage can be instantaneous, severe and irreparable.
What causes it? On return of mains supply after power cuts , under-sized utility oscillating between periods of brown-outs and over-voltage of accidental.
