What is a bibliography ?
A surge or transient is an overvoltage spike or disturbance in the power waveform that can shorten the lifespan or destroy electronic equipment at home, in the office, or in a factory. Surges can reach tens of thousands of volts in size and last for several usec. In our lives, devices using microprocessors, such as computers and answering machines, are increasing at a very rapid rate, and surges can cause the following damage to these devices:
* Damage to equipment
* Reduced productivity/downtime
* Other economic losses
What is a Surge?
Surges, or transients, are brief overvoltage spikes or disturbances on a power waveform that can damage, degrade, or destroy electronic equipment within any home, commercial building, or manufacturing facility. Transients can reach amplitudes of tens of thousands of volts. Surges are measured in microseconds.
The presence of sensitive electronic equipment such as computers, answering machines, microwaves, and other microprocessor-based equipment is growing exponentially in virtually every aspect of life. Surges can cause damage, resulting in:
* Equipment loss or damage
* Lost productivity/down time
* Other financial losses
What are the dangers of surges ?
Some vulnerable devices that can be found around the home or office are as follows.
* Industrial equipment - machinery, motors, air conditioning equipment, cash registers
* Office equipment - PC, printer, FAX, copier, modem
* Home appliances including home theater
* Telephone, answering machine
* Crime prevention equipment
*Sprinkler
* Transparent fence
* Landscaping lighting
What is at Risk?
Here is a partial list of vulnerable equipment in and around your commercial or industrial facility or home:
* Industrial or commercial equipment - machinery, motors, HVAC, cash registers
* Office equipment - personal computers, printers, fax machines, copiers, modems
* Home appliances and theater equipment
* Telephones and answering machines
* Security systems
*Sprinkler systems
* Invisible fences
*Landscape/pool/outdoor lighting
