The
advent of automation and process control systems has set up
a rapid pace of development in the electronics industry. Not
surprisingly, there is demand for better reliability of electronic
equipments and control systems. A major factor affecting the
reliability of these systems is the transient overvoltage
or surge in power line. Despite their short duration, these
transients are extremely damaging to modern electronic equipments
wherein advanced ICs and other components are used and are
very sensitive to such high voltage surges. Major failures
in sophisticated electronic systems are attributed to these
transients. Besides failure in electronic systems, these transients
can also affect electrical systems by damaging transformers,
contactors and similar components via insulation breakdown,
spark-over etc. |
