Have you ever noticed a small spark when you plug an appliance into an outlet? This may be normal or it could be cause for concern, depending on the size and frequency of the electrical outlet sparking. It’s important to recognize the difference between a normal spark and a dangerous one—as well as possible causes for outlet sparking—so you can pursue an electrical repair if necessary.

The supply line that carries electricity through your home measures about 115 to 240 volts with a frequency of 60 hertz. In layman’s terms, this means the flow of electricity runs very fast and hot through the wires behind your walls.

Electrical outlets tap into this fast-flowing stream of electricity, powering everything from your lamps to your laptops to your coffee maker. A small blue spark arcing from the outlet to the plug can occur as the appliance suddenly draws amperage and electrons begin to flow through the cord. Once the flow steadies, the spark should disappear. This type of electrical outlet sparking is completely normal and comparable to static electricity.

Electricity generates heat as it travels through wires. Insulation surrounding a wire may begin to melt, exposing the bare wire. If it comes in contact with the metal outlet casing or even another wire, electrons can leap out of the wire and create a dangerous spark. This is called short circuiting and could cause an electrical fire if not repaired promptly.

Short circuits may be caused by a number of things, including old outlets with loose connections and too many appliances being plugged into the same outlet via a power strip or extension cord.

Water and electricity don’t mix. That’s why bathrooms should have special outlets called ground fault circuit interrupters (GCFIs). These outlets automatically shut down the circuit when they detect water, which can help prevent electrocution and house fires. If the bathrooms in your home have ordinary outlets, you should have an electrician replace them with GCFIs.

If you’ve had an electrical problem in the past, you may have attempted to perform a repair yourself or used a cheap electrician. Electrical wiring can be extremely dangerous if you don’t the proper licensing and qualifications and lead to potentially serious issues, electrical outlet sparking being just one of them. Fortunately, a professional electrician can undo the damage and make your outlets safe to use once again.

Mechatronics, or mechatronic engineering combines mechanical and electrical engineering to design innovative products and systems. These systems must rely on mechanical and electrical components working together in harmony.

The list includes DVD disc drives, anti-lock braking systems, manufacturing, electric motors and clothes dryers, among others. These devices require electronic controls and feedback systems to interact seamlessly with their mechanical design.

Motor control systems operate by using a programmable logic controller or PLC. This system allows advanced programming and algorithms to dictate a motor’s behavior. Therefore, they can be programmed to control multiple motors or VFDs. A robotic arm or a large factory machine is a good example of this.

In addition, PLCs can accept inputs from a wide range of sensors and switches. This allows precise feedback from the machine it controls. Furthermore, it executes built-in software.

The smallest high-precision motors, DC motors, found in computer hard drives and DVD readers. Due to their miniaturization, they can be easily controlled by computer software to perform nearly any imaginable task. A battery powered quad-rotor drone offers us a prime example of DC motor control. Accelerometers and gyroscopes feeding data into a computer controller adjust the speed of each motor independently to keep the drone flying level.

A simple technology that combines electric motors with feedback control, known as servomechanisms, provides valuable information. They utilize a small electric motor, gearboxes, and a potentiometer to produce accurate position feedback to the motor itself. This ensures that the motor has moved to the correct position. Thus, precise movement control of a motor is possible. Applications of servos include RC car steering, fly-by-wire systems in aircraft, robotics, and industrial control valves.

Servos communicate with computer systems, allowing them to be part of larger mechatronic systems, so they can be controlled by PLCs and computer algorithms.

The field of mechatronics constantly evolves. Therefore, as it does, it incorporates cutting edge computer software and mechanical design, bringing to life new inventions. These breakthroughs make modern-day living much easier and more fun.

Tired of breaking the bank just to keep up with the Joneses? Forget fancy cars and other status symbols. How about a way to maintain a friendly neighborly competition that actually involves saving money instead of spending? Americans have a wealth of resources at their disposal to empower families to cut back on energy consumption and reduce their electricity bills, but we don't do a stellar job of taking advantage of that information. Recent research, however, has shown that homeowners are more likely to take efficiency measures with their electrical work when they can compare their own consumption to that of their neighbors.

Whose Bill is the Lowest?

The experiment took place last summer, when the Vermont utility company Green Mountain Power worked with Opower, a software company that specializes in behavioral economics. During very hot days when air conditioning use was expected to be high, the utility reached out to customers with tips on reducing the amount of energy they need to power their home electrical work.

Afterward, the utility gave a report which ranked households in the neighborhood based on how well they had done on cutting back. By the end of the summer, electricity consumption among Green Mountain customers had dropped by five percent during hot days. That's some serious savings!

Peer Pressure at its Best

That five percent resulted from simple behavioral changes like bumping the thermostat up a few degrees and using curtains to block out sunlight during the hottest part of the day – no major investments or new equipment needed, just a little peer pressure. This research should be useful in helping understand what motivates people to save energy in order to develop more effective outreach programs for utility companies around the country.

One of the big takeaways is that the utility didn't give its customers any kind of incentives or payments to change their behavior – just the money they saved through efficiency, and the bragging rights of being more conservation-minded than their neighbors.

"Some of the decisions we make are not entirely rational, and they are due to a lack of context," Kevin Hamilton, Opower's vice president of marketing, said to Utility Drive, "and by providing that context you can encourage individuals to adjust their usage in ways that can benefit both the customer and the utility as well."

Little Changes Mean Big Savings

People come up with all kinds of reasons not to implement efficiency measures: It costs too much in initial capital, they are too busy to think about it, or they simply don't think the savings are worthwhile. But the reality is that even making small behavioral changes can add up in the long run.

If you want to decrease the cost of your electrical work and impress your neighbors, have a qualified home services technician perform an energy audit on your house to identify the most cost-effective ways for you to cut back.

One of the least understood terms in LED Lighting is efficacy, or in simpler terms, how efficient is the light. It is typically measure in lumens/watt. Today, efficacy is becoming more and more important because efficacy varies greatly from product to product. What the consumer needs to be wary of is that you should not be mislead into thinking that just because you are switching from HID or fluorescent to LED that you are getting the best savings available. You also need to look at how efficient the LED product is to maximize the savings.

Here is an example of how this works. Let’s look at a two USA Made competitors LED Retrofit Kit compared to our 4th generation LED kit. All three units are designed to replace 400W HID

From this table, you can see that all products produce over 13,000 lumens, with the MyLEDLightingGuide product producing the most at 14,528 total lumens. It also consumes the least amount of energy of the three units at 105 watts, compared to 130 and 135 watts. For the record, all three products come with a 10 year warranty on the head and a 5 year warranty on the driver. MyLEDLightingGuide also offers a 10 year warranty on the driver as an optional upgrade.

But what does this all mean in terms of saving you $’s. Let’s take a typical scenario. Let’s say these retrofits are installed in MyLEDLightingGuide 105W retrofit kit. Multiply this number over 10 years and by the number of fixtures you have to replace, and this is real dollars. And let’s not forget the MyLEDLightingGuide retrofit kit is also much brighter than the competitors products.

So efficacy is important. It saves you money. But a well designed kit will also produce more light. Just think, without efficacy we wouldn’t have as great of savings, nor would we have more light production from the same amount of power.

Efficacy is huge in the world of lighting, and it is only going to get better year by year. Technology improves, lights improve, and thus; efficacy improves. In 10 years, lights that will be made are probably going to be 5x improved then they are today. And since they are already super efficient today, just imagine that times 5. Now that is efficacy!
