Keep Your Computer Plugged In
Anything that’s plugged into an outlet in your home is at risk of suffering damage from an electrical surge during thunderstorms. If an electrical storm has been forecast, unplug your computer, laptop, and other devices, and consider unplugging appliances.
What is a UPS and why is it important?
An uninterruptible power supply (UPS) is used to protect critical loads from utility-supplied power problems, including spikes, brownouts, fluctuations and power outages, all using a dedicated battery.
How long does a UPS last without power?
How long can equipment on a UPS keep running after the power goes? A. That depends on how big a UPS do you have and what kind of equipment it protects. For most typical computer workstations, one might have a UPS that was rated to keep the machine alive through a 15 minute power loss.
Should I keep my UPS plugged in all the time?
A UPS should always be plugged in to house power and charge until it is fully charged, and remain that way until you run in to a power outage.
How long do battery backups last?
Run-time of a new fully-charged battery
As a general rule of thumb, during a power outage most new fully-charged batteries will last roughly 5-7 hours of continuous pumping and roughly 1-3 days of non-continuous pumping depending on the frequency.
What are UPS limitations?
Packages can be up to 150 lbs. Packages can be up to 165 inches in length and girth combined. Packages can be up to 108 inches in length. Packages with a large size-to-weight ratio require special pricing and dimensional weight calculations.
How efficient are UPS?
New energy-efficient UPSs generally range from 92% to 95% efficient. However, a UPS does not always operate as efficiently as its rating suggests. Instead, its efficiency follows a curve based on its “load factor” —how much of its power capacity is being used.
What are the components of power system protection?
There are three principal components of a protection system: Transducer. Protective relay. Circuit breaker.
What are the 7 requirements of protective system?
Protection System Requirements and some basic terminologies used
- Reliability:

How often should a PC be cleaned?
As a rough guide, give your computer a clean every 3 to 6 months. Computers kept on the floor will need to be cleaned more often, as this low placement allows dust and dirt to creep in more easily. Our advice is to clean your computer now, then again in about 3-4 months.
Can I use a hair dryer to clean my PC?
No, just no. Don’t do that. Go get some compressed air like a civilized person. Every other possible thing aside, the broad expanse of air that comes out of a hair dryer compared to a can of compressed air is just going to move stuff around a bit more than a fan would.
Which device should you use to protect against power outage?
An uninterruptible power supply can save data during an outage, and a surge protector can prevent damage from a surge. Surge protectors absorb or ground overvoltage from spikes. Each time a surge protector does its job, resulting damage can reduce effectiveness for the next surge.
Should I unplug my TV during a power outage?
Televisions, computer equipment, advanced technology washers and dryers, game consoles, fans, lights, etc., should be unplugged, especially if they were in use when the power went out.
Should I unplug my washer and dryer when not in use?

Power Outage Tips
Keep freezers and refrigerators closed. Use a generator, but ONLY outdoors and away from windows. Do not use a gas stove or oven to heat your home. Disconnect appliances and electronics to avoid damage from electrical surges.
What happens to a computer during a power surge?
A power surge occurs as soon as the flow of electricity gets interrupted and started again. This places electrical pressure on the wires in your computer, causing them to heat up and burn. Some wires may melt, and even if your computer survives the surge, the strain alone can cause damage in the long run.
What causes a power surge in a computer?
Power surges are most often caused by power interruptions and changes in electrical draw including the demands of other equipment sharing the same power supply. When appliances with a heavy draw turn on and off they can cause surges in your system due to fluctuation in demand.
