We see from your search that you're looking for information on the term "Overvoltages",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Surge arresters protect power lines from
ABB Power Technologies, which we summarised at the time by saying "The Pexlim surge arrester is a sacrificial device, designed to fail safely to limit overvoltages to an acceptable level".
Several months prior to that,
we featured the news release Eaton launches new control devices for OEMs from
Eaton Corp: "A new family of compact control devices - contactors, starters and overload relays, manual motor starters, combination motor controllers, relays and timers - is announced by Eaton for the OEM market".
In December 2006, we covered the news from ABB Power Technologies
concerning its Surge arrester retrofit service
- take a look at Surge arrester retrofit protects electrical assets
which says: "Specialist surge arrester retrofit service enables substations to be upgraded to a high level of protection against the damaging overvoltages created by lightning strikes".
Take a look also at the news release from Eaton Corp, Control components meet global OEM demands,
as well as Voltage limiters take on surge arresters from ABB Power Technologies,
and Matrix filters promise harmonic solutions from Silverteam.
