It is very necessary and important that appliances and
similar kinds of equipment have reliable protection against
transient voltage conditions because it is very common that
these types of equipment can suffer significant damage
caused when a transient voltage appears in the ac voltage
line. Transients arise internally from normal circuit
operation or externally from the environment. The latter is
particularly frustrating because the transient characteristics
are undefined. A statistical description can apply though.
Greater or smaller stresses are possible. Long duration high
voltage transients are much less probable than those of lower
amplitude and higher frequency.
