From your cell phone to your washing machine, you’ll find all kinds electronics in your home.  Entertainment, lighting, comfort, and even cleaning can be electrically powered.  Most people know that it’s a good idea to disconnect electronics during an electrical outage or lightning storm.  This is due to possible electrical surges.  Electrical surges are sudden increases in current that can damage connections and electrical components throughout your home.  Most devices have some protections, but strong surges can overpower these protectors, leaving you with a very expensive paperweight after the surge is through.  Fortunately, surge protectors exist to stop this from happening.

A sudden increase in current occurs when more power is being delivered to the same system.  If a lightning storm strikes a transformer or relay that’s connected to the same grid you’re on, excess power is diverted to your home and creates an increase in current.  This sudden surge is what damages components.  But, it isn’t just limited to sudden electrical discharges either.  When power is applied to a system, it has substantial initial current.  This is known as inrush current and is the reason that you’re advised to disconnect electronics whenever there’s an outage.

Once power is restored to a system, either because you turn on a switch or the power grid is reconnected, initial current surges into the system.  Disconnecting devices helps to decrease that inrush current.  The electrical panel in your home is also designed to handle inrush current, which is why your breaker system doesn’t automatically trip whenever power is restored.  On a smaller scale, any sudden call for extra power pushes a small surge into the system.  When you power up an electric vacuum cleaner or portable space heater, there’s a small surge.  The more powerful the device, the larger the surge.  These are the types of surges that common surge protectors guard against.  For lightning strikes you’ll need something better.

While the majority of surges are protected against by those tiny power strips, because most surges originate inside your home, they aren’t strong enough to protect against the dangerous surges that will irreparably damage your in-home electronics.  Most homewoners prefer the power strip surge protectors because they’re inexpensive.  But, while a whole-home surge protector can cost over $200 to add on to your home, they don’t suffer from many of the drawbacks found in the tiny in-home protectors.

Whole-home surge protectors guard your entire home from outside surges.  They’re installed near and wired to the electrical service panel for your home.  Any power surge that travels to your home is immediately shunted away, preventing disaster from ever reaching your home.  You’ll find that whole-home surge protectors are also not as fragile as standard home surge protectors.  They’ll last for years and are less likely to be burnt out by a single surge.  A quality surge protector is capable of shunting tens of thousands of amps without burning out.

If you want the best in electrical protective devices, a whole-home surge protector is the right choice.  Compared to most safety installations, they’re relatively inexpensive and you only need to install one device to protect your home for years.  It’s still a good idea to use power strips to protect in-home devices from smaller surges, but you need a quality surge device to protect against lightning storms or substation surges.

As a Plano TX electrician, I can tell you that the year 2011 was a dramatic and eye-opening experience for those of us who realized that our electrical grid is unreliable when it attempts to function in less-than-ideal situations. Any Plano electrician can tell you that without viable solutions to the problem of an easily weakened power grid, North Texas runs into difficulties which can be both costly and potentially dangerous.

North Texas Electricity: A Year In Review

Let’s take a look at the last year’s power grid problems and how they affected our North Texas population.

Indoor Generator: Taking Matters Into Your Own Hands

Given all the difficulties we experienced last year as a result of an unreliable power grid, isn’t it time for us to consider solutions that would put reliable power back in our homes? One of those solutions that is worth taking a look at is an indoor generator. Having an indoor generator in your home can:

Consider talking to your Dallas electrician today to find out more about indoor generators and how you can be prepared in 2012 for any blackouts and outages that come our way.

ballast-compatible LED T8 tube for office lighting, school lighting, hospital lighting, basement lighting, and more. The energy-efficient F32T8 tube light can be used in direct-wire fixtures or to replace T8 tubes in fluorescent fixtures without removing ballasts. Designed to last 50,000 hours—5 times longer than fluorescent tubes—the LED T8 tube reduces costly repairs, disposal fees, and the need for replacements. This energy-efficient LED light uses just 18 watts of power and is comparable to a 32-watt fluorescent tube light.

Looking for new ways to reduce your electricity bills? The Department of Energy is on the job. The agency is sponsoring research that could help decentralize the nation's electrical grid – instead of powering your electrical work from large generating stations, you could create your own electricity on-site by burning natural gas. As a bonus, the equipment could provide homeowners with heat energy as well. Read on to learn more about the Energy Department's program to spur the development of small generator technologies.

Advanced Electrical Work for Your Home

The projects are part of the Department of Energy's Advanced Research Projects Agency-Energy (ARPA-E), which is spending $55 million to support research and development into various technologies that could strengthen the flexibility, dynamism and independence of the nation's energy production system. The generator-related programs, known as GENSETS, or GENerators for Small Electrical and Thermal Systems, are receiving $25 million of the funding.

In addition to the GENSETS projects, the Energy Department is also sponsoring a program called Transportation Energy Resources from Renewable Agriculture (TERRA), aimed at developing biofuels.

“The GENSETS and TERRA programs demonstrate ARPA-E’s unique approach to developing innovative ideas to advance energy technologies,” ARPA-E Director Dr. Ellen D. Williams said in a statement. “ARPA-E is pushing the boundaries of current energy technologies to create a more secure, sustainable and affordable American energy future.”

Waste Not, Want Not for Excess Heat

The GENSETS technologies being developed are similar to microtrigeneration systems, which use natural gas to create electricity and capture excess heat for hot water and general home heating. With one of these systems, you'd still have a gas bill to pay – but if you combined your equipment with rooftop solar panels, you could reduce the cost of powering your home electrical work to a minimum.

The generator technology already exists and has been deployed to a certain extent, but the Energy Department program hopes to further refine the devices and make them more efficient, reliable and affordable. Twelve different teams are working on generator projects to take the equipment as far as it can go to meet the needs of the homeowners of today and tomorrow, focusing variously on internal combustion engines, Stirling engines, micro-turbines and solid state devices. One technology could end up being a clear leader and push the others out of the field, or multiple engine types could be competitive and give consumers a choice in their home electrical generation system.
