We see from your search that you're looking for information on the term "Voltage Spikes",
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 Relay offers AC motor solid state switching from
OEM Automatic, which we summarised at the time by saying "The SLO24TRA's relay input is operated with 24V DC and the output can switch load voltages from 0 to 240 VAC".
A few weeks before,
we featured the news release Soft starts reduce damage for recycler from
Silverteam: "Soft start technology helps Axion Polymers maintain demanding processing 24x7".
In March 2007, we covered the news from WEG Electric Motors (UK)
concerning its Motors adopt new insulation
- take a look at Motors adopt new insulation
which says: "Insulating materials using a laminate of Nomex offer a high thermal classification (220C), high mechanical strength, outstanding electrical qualities and superior thermal resistance".
Take a look also at the news release from Linos Photonics, Amplifier enables subnanometre resolution,
as well as Power cuts are only the tip of the iceberg from Powervar,
and LED technology offers brighter indicators from Schneider Electric.
