Know these before using a computer


Surge:

Surge is an increase in voltage in an electrical current that causes damage to electrical equipment. If an electrical current above the rating were to come through a power outlet for more than three nanoseconds this would be considered a surge. Anything less than three nanoseconds is considered a spike.


Spike:

Spike is an increase in the amplitude of a signal for less than three nanoseconds. Anything more is considered a surge. A power spike can damage any electrical component.


Surge protector:

Surge protector is a plug-in device, designed to protect any electrical equipment from surges and spikes. It is also known as a surge suppressor.


Voltage drop:

Voltage drop is decrease in voltage in less than one second. It is also known as brownout, dip, voltage reduction, and voltage sag.


Under voltage:

Under voltage is reduction in voltage for more than one second.

Voltage drop or under voltage damage your electrical equipment like computers. To prevent damage, use UPS.


UPS:

UPS means Uninterruptible Power Supply. It is a device, to provide backup power source in case of a power failure (outage /blackout), brownout, or a surge in power.
