Transient overvoltages are large, very brief and
potentially destructive increases in voltage which
can be caused by
1.
The secondary effects of lightning strikes (either
between clouds or to ground) from a kilometre, or more, away
2.
The electrical switching of large inductive loads (such as
motors, transformers and electrical
drives), or capacitive loads (such as power factor correction equipment).
Although
they only last thousandths or millionths of a second, transient overvoltages
can devastate modern electronic systems: disrupting
system operations, through data loss, data and software corruption and unexplained
crashes degrading equipment components and circuitry, shortening equipment
lifetime and increasing failures destroying components, circuit boards and
I/O
cards causing costly and unnecessary system downtime
