Do your lights flicker regularly? When you turn on your dishwasher or any other heavy appliance, do your lights dim briefly? Not only is this frustrating, but it could be the sign of a more serious electrical issue. While most people simply tolerate flickering lights, it’s best to understand what can cause flickering lights and why it’s important to get it corrected as soon as possible!

If your lights are flickering, contact the electrical experts at Kolb today! We’ve been servicing the Washington, DC, Maryland, and Virginia area since 1925, so we have plenty of experience in fixing all of your electrical issues! 

A flickering light can simply be caused by a loose or defective bulb. This is about the only cause of flickering that a homeowner should attempt to fix on their own. With the light turned off (and fully cooled!), gently remove the bulb from the socket and inspect it. The glass bulb should be firmly affixed to the metal base—if it wiggles in the base at all, it’s defective and needs to be replaced. If the bulb is good, screw it firmly into the socket and test it for flickering. If it still flickers, another problem exists.

If the lights flicker at a certain time, or at a regular interval, pay attention to your other electrical demands during that time. An HVAC unit, clothes dryer, or other large appliance can put a heavy demand on your electrical service. If the lights flicker when other appliances kick on, there may be a problem with the appliance or service wiring. This is more than a nuisance—increased current draw can cause wiring, connectors, and breakers to heat up, presenting a real risk of fire. Even without the risk of fire, appliances that have to struggle to draw power can suffer damage to motors and other expensive components.

Defective wiring is another common cause of flickering lights. Undersized breakers, loose connectors, or damaged wires can all cause intermittent current losses. If your home has a mixture of copper and aluminum wires, special connectors must be used where the two types of wires meet. If the wrong connectors were used, they can corrode, causing flickering and other problems. Any defects in your home’s wiring can create a risk of fire or electrocution, and can render safety features like breakers and GFCIs ineffective.

Find your angle. 

Playing with the direction and angle of your light source is essential. With the right play between light and shadow, you can accent the most titillating parts of your dish, while camouflaging any flaws. Texture greatly contributes to the delicious appearance of most any meal. Notice how the angle of the light below highlights the different textures within this broiled flank-steak sandwich.

Thinking back to the Big Freeze in February might make you shiver.  Many of Dallas’ residents were stuck indoors for days on end, unable to even get out of their driveways.  But perhaps the worst parts of the early February freeze were the rolling blackouts that some residents suffered.

According to Oncor, the power delivery company in North Texas, 1.3 million residents were affected by these blackouts.  Luminant, the biggest power provider in the state, lost 11 coal and natural gas generators on February 2.  This trickled all the way down to North Texas residents, and even fire stations and police stations were stuck without power.

Losing power during a cold snap can be quite an an inconvenience.  If you’re without power for an extended period of time, you might have to incur extra costs, or even face the danger of driving on icy roads by going out to eat, or even be driven out of your home to a hotel room to stay warm for the night.  In the office, or even at home, a sudden power outage can cause you to lose precious data on your computer as well.  So what can you do to prevent these things from affecting you in the future?  Install an emergency power system.

An uninterruptable power supply (or UPS) provides emergency power to your home in the event of a power outage.  Designed to provide instant backup power, a UPS uses batteries or diesel generators to keep you up and running.  There are a variety of types of uninterruptable power supplies, and a Dallas Electrician can help find the one that will fit your home or office, and can install it safely for you.

So, before you’re left in the dark or cold again, talk to a local electrician in Dallas about the different emergency power systems available for you, and which one will best fit your needs.  They will be able to assess your situation and make sure your power system is safely installed.  Then, the next time North Texas suffers from rolling blackouts, you’ll be able to rest easy knowing your family and home is safe from the heat or cold.

Nearly every single person living in the United States relies on the electrical grid. It's how electricity gets from the power plant to your home, powering your devices and appliances. With no grid, none of the electrical work in your home will function – no television, no air conditioning and no electric lights. Our grid is changing, however, taking advantage of evolving technology on both the distribution and consumer side of the equation. Read on to learn more about how our electrical grid will evolve to meets the needs of the 21st century.

How to Balance Supply and Demand

The electrical grid is not a single object, but rather a giant network of power plants and transmission lines that spans the entire nation. In order for electricity to flow from the generating stations into your home’s electrical work, the grid needs to be able to meet the demand at any given time and place. This can be an enormous challenge – if there is too little production, consumers can be subject to annoying and damaging brownouts. Ramping up generation to meet variable demand is expensive and inefficient, however.

Some utilities solve the problem with time-of-day pricing, charging more during the day and less at night to smooth out demand. Smart technology, however, will allow us to fine-tune the grid even further to increase efficiency, improve communication and mitigate blackouts or other power outages.

Smart Meters and Dispersed Generation

Smart meters are one of the first steps toward our new grid. These meters track residential electrical consumption in real time and can communicate with the utility company instantaneously. They can allow producers to better predict demand, respond immediately to dips and spikes, and further refine variable pricing structures that incentivize people to use less electricity during peak hours. Smart meters also give homeowners the power to see where and when they are putting the most stress on their electrical work, allowing them to adjust their behavior strategically.

Changes are coming to the generation side as well. Traditionally, the electrical grid is powered by large, centralized power plants, but residential solar installations mean that generation is becoming more widely distributed. Wind generation is also becoming an ever-larger factor in our nation's energy supply. This means that the grid needs to be updated to become more flexible and adaptable, but there is a large payoff in sight – the more dispersed that power generation becomes, the more resilient the grid will be in the event of an outage, with smaller regions able to supply themselves with emergency power if they are cut off from the centralized system.

Makes Tomorrow's Energy Grid Work for You

No one knows exactly what the power grid will look like 100 years from now, but the nation is well on its way to updating its electrical infrastructure to meet the needs of this century. If you have any concerns about how your electrical work will interface with the power grid of the future, or need any other work done on the wiring and circuitry in your home, call an expert electrician today.
