EIT has seen quite a few equipment losses recently. Several of these have not been tied to storms but just short power interruptions. Power being restored to an area can often create a surge, and that is what we have been seeing.
The electronic equipment in the offices should be plugged into surge protectors. The job of a surge protector is to shunt small momentary spikes in power away from the system plugged into it. These small momentary spikes can be caused by appliances like copiers, AC units, refrigerators, or they can come from the power grid feeding the building.
Surge protectors are not intended to stop a direct lighting strike. The surge protector will help with power fluctuate caused by the power being interrupted or restored due to a storm.
Not all surge protectors are created equal. There is a very wide range in the cord length, layout, size and abilities of surge protectors on the market. There are three ratings that should be present on a surge protector, Joules, Clamping Voltage, and Response Time. Below are the recommendations for a surge protector:
Joules: 1000 or greater
Clamping Voltage: 400 Volts or lower
Response Time: 10 Nanoseconds or less
Most surge protectors that will meet these specification will cost $25.00 or more. More information on surge protectors can be found at http://computer.howstuffworks.com/surge-protector7.htm.
There is a lot of equipment lost from electrical surges that travel through the network cables. These surges are caused by either nearby lightning strikes or excess power running in over a device that is on the network. Surge protection for network cables does exist. Two products that can protect the network side of a device are:
Tripp Lite 2 Outlet Notebook Surge Suppressor
Tripp Lite RJ-45 10BASE-T Token Ring Dateline Surge
