What Is An Uninterrupted Power Source


Go to top.

An uninterruptible power supply (UPS) provides backup power when there is a blackout or your main power source goes out for some reason. It differs from an emergency power system, which takes time to activate because it kicks in instantly during an outage. If you cannot afford to lose power during a project – like an all-day download – a UPS is your best option to protect against data loss and prevent system interruption. That’s why it’s called uninterruptible because it completely overrides an outage.

There are three main types of uninterrupted power supplies, namely the online, the line-interactive and the standby. An on-line UPS accepts a alternating current (AC) input, converts it into direct current (DC) to send it through the rechargeable battery, and then turns it back into an alternating current to power the protective equipment. A line-interactive UPS redirects the battery’s DC path from charging mode to supplying mode during an outage. It’s a very intuitive machine that can maintain power reserves during continuous Undervoltage or overvoltage situations by selecting the perfect amount of backup power to supply. A standby system (also known as an off-line system) is directly powered by a standard AC wall outlet, and it only provides backup power if the main power source fails. Standby UPS systems are the simplest and most popular type for personal computers, offering basic features like surge protection and a backup battery.

For especially large power needs, a dynamic UPS is appropriate. Dynamic models use a synchronous alternator that is connected to the main equipment through a choke. The unit stores energy in a flywheel, and during an outage, an Eddy-current regulator holds onto the power. Recently, technicians developed a fuel cell UPS, which is more environmentally friendly and quiet. It uses hydrogen and a fuel cell as a power source and is ideal for small areas.

Common Causes Of Power Outages


Go to top.

There are several reasons the power goes out ranging from human error to natural disasters. In a strong storm, a tree can fall on a power line, breaking it and cutting off power to an entire neighborhood or town. If you live in an area with extreme weather, always let the city tree trimmers do their mandated work in your yard – they are doing it for your safety, and possibly removing shrubbery that’s too close to a power line. If a storm doesn’t cause a tree to fall, it could send a lightning bolt into a power line, or cause a flood that damages above or below-ground electrical equipment.

If you live in an area with a lot of wildlife activity, a UPS can be invaluable. An animal can crawl onto a transformer or fuse, causing the equipment to automatically shut down to protect the rest of the system, rendering you powerless. If you live in a remote area, you could be tens of miles away from a building with power, so you need to provide your own.

Construction work on your property or street can cause a power outage. Workers can accidentally drill into a power line, or back a tractor over one. A car crashing into a pole could cause an outage, too. Familiarize yourself with important safety precautions, in case there is ever a loose power line on your street. In addition to having a UPS ready, you should know what to do if you can't regain power for several hours.

The Largest UPS In The World


Go to top.

In Fairbanks, Alaska, where temperatures can drop as low as negative 50 degrees Celsius, power outages used to be a common problem. The remote nature of the state means an outage could be very dangerous since the only way for residents to travel to another state is by boat or plane. If communication towers are down, navigating either of these vessels is dangerous. Within Alaska, there are also people living in almost total isolation, so they’re nearly helpless if their power fails. People simply cannot survive if their heater breaks in the negative 50-degree weather.

In August 2010, technology group ASEA Brown Boverithe (ABB) installed the world’s largest UPS in Fairbanks. The system is made up of a converter designed by ABB, and nickel cadmium batteries created by battery manufacturer Saft. The converter turns the batteries’ DC power into AC power and can produce up to 27 megawatts of power for 15 continuous minutes. That quarter of an hour gives the system time to retrieve backup generation. The system can deliver 46 megawatts of power for an even shorter time frame, but Fairbanks primarily needs it to deliver power just long enough for the backup generator to start up.

The UPS can operate in seven different modes, one of which is automatic scheduling, which offers immediate system support if a breaker trips on a transmission line or local generator. It also has a power system stabilizer mode, which works to dampen power system oscillations. In charging mode, a dispatcher controls at what rate megawatts charge the UPS, and when the system can begin charging again after an emergency discharge.


#10.APC Back-UPS 550VA UPS Battery Backup & Surge Protector (BE550G)


I purchased this to replace a previous APC UPS which I had had for many years -- I replaced the battery twice, and it was time for a new one. Lucky for me, about a week after setting it up, we had a power outage and this one kept my system running for quite a while. I didn't feel like I had to scurry around real quick to shut things down. The other thing that I like is the ability to shut off the beep without turning off the unit, so after being warned, I was able to get rid of the annoying, but helpful beeping, but still have the backup.
