efficiently as possible. Your attic fan can be installed one of two ways, either gable mounted or roof mounted, and is controlled by an automatic thermostat that shuts it off or turns it on.

An attic fan will perform as effectively as it should in a properly sealed and insulated attic, so that no heat or moist air can sneak its way in. This helps with your HVAC efficiency, and also protects your roof and your attic’s structure.

Your attic fan serves as a way to efficiently ventilate the space, but it is so much more than that, too. As we stated above, the temperature in your attic can be far above the outdoor temperatures. This is if you do not have an attic fan installed. Regular vents do allow for some cooling, but not to an extent that you’ll notice the difference.

A properly installed and serviced attic fan can help drop your attic temperatures by as much as 50 degrees, making your entire house cooler. This means you’ll be able to turn up your air conditioner’s thermostat by as much as 10 degrees, but still remain comfortable.

In the wintertime, moisture can quickly turn to ice or frost, and as that expands in can damage your roof and the structural integrity of your attic. An attic fan, however, can fend off the moisture before it is able to damage your roof in this manner.

Ice is not the only danger that moisture brings, either. When moisture cannot be ventilated and is left to sit, mold can start growing. Unfortunately it’s very easy for moisture to reach your attic—even your showering and cooking allows this to happen. But an attic fan can resolve this problem.

Your air conditioner will not have to work so hard to do its job when it is assisted by an attic fan. Also, it’s likely to last a lot longer—given that you schedule regular maintenance—when you don’t have to run it as often. Repairs will happen from time to time, but an efficiently working AC system is a lot less likely to give you problems than one that doesn’t have the assistance of an attic fan.

The controller keeps on monitoring the application requirement in a continuous control loop. It then commands the inverter to produce the required voltage and frequency to meet the application requirements. To do this, the controller, comprised of a microprocessor, takes the input signal from the sensor and compares this with a reference signal. It then generates the appropriate control signal for the inverter to vary its output power.

In a typical application, the controller will monitor process parameters such as pressure, flow rate, temperature or liquid level. For example, an oxygen sensor in a boiler provides a signal to adjust the speed of the fan and control the amount of oxygen in the boiler system.

Today’s drives, using microprocessors, semiconductor power switches, and SMDs are now smaller, compact, cheaper, more reliable and efficient. A typical drive will also include a filter to suppress harmonics generated when converting the DC to AC voltage.

At first glance, you might not notice much of a difference between your current electrical meter and your new Smart Meter. But inside, your Smart Meter is hard at work using advanced technology to identify and analyze data about your home’s energy consumption. These meters then communicate this data between your home and BGE via a secured network.

BGE began installing these advanced meters back in 2012, and they’re slated to finish rolling them out to every home and small business in their service area by 2015. Smart Meters can do some pretty amazing things, including:

You may already be used to your home’s existing electrical meter, which keeps an ongoing record of your home’s energy use and must be read by the power company each month so you can be billed appropriately. A Smart Meter, on the other hand, allows for two-way communication between the meter and BGE via a wireless network—a crucial point for building a reliable smart grid.

When you first get your new Smart Meter, you may notice that it seems to function just like your old one, without any of the supposed benefits of installation. This will be true at first, but over time, you’ll be able to experience everything the Smart Meter has to offer.

Best of all, Smart Meters have been thoroughly tested for safety and reliability. These meters are already in use across the country, and they have undergone extensive testing by other utility companies. Smart Meters operate at a level that is much lower (1.4%) than the maximum permissible exposure limits for radio frequency, as defined by the Federal Communications Commission. Smart Meters transmit for an average of about two minutes a day.

BGE will be installing Smart Meters throughout 2014. During that time, every BGE electric customer will receive one for their home. The utility provider will upgrade existing gas meters during this time period as well.

Several weeks before BGE begins installing Smart Meters in your community, you will begin seeing notifications in various forms, including ads in your local paper, materials at your neighborhood library or grocery store and booths at community festivals. A few weeks prior to installation, you will receive a letter in the mail informing you of when your new meter will be installed, or, if your meter is inside your home, providing you with instructions on how to schedule an appointment. For outdoor meters, you do not need to be present for installation. We’ll leave behind a door hanger to confirm that a new meter was installed.

Once your meter is installed, you’ll be granted access to BGE Smart Energy Manager, which will provide you with the tools necessary to better understand how you use your energy, and how to better save energy and reduce your bills.
