8.12.6 Application
Voltage variations are the most typical power quality variations on the public electric
network. Typically, short-duration voltage variations are defined to last more than half of
the nominal frequency period and less than one minute (European Standard EN 50160 and
IEEE Std 1159-1995).
These short-duration voltage variations are almost always caused by a fault condition.
Depending on where the fault is located, it can cause either a temporary voltage rise (swell)
or voltage drop (dip). A special case of voltage drop is the complete loss of voltage
(interruption).
