It is very necessary and important that appliances andsimilar kinds of equipment have reliable protection againsttransient voltage conditions because it is very common thatthese types of equipment can suffer significant damagecaused when a transient voltage appears in the ac voltageline. Transients arise internally from normal circuitoperation or externally from the environment. The latter isparticularly frustrating because the transient characteristicsare undefined. A statistical description can apply though.Greater or smaller stresses are possible. Long duration highvoltage transients are much less probable than those of loweramplitude and higher frequency.
