Three-phase transformers have three low voltage and three high-voltage windings. Each winding has two end points that can be connected in various ways. Depending on whether the winding ends are connected to each other or to a common ground, the transformer connection type is a combination of wye and delta connections. Power-grid designers use these different transformer connection types for stepping voltages up or down and the different types have various advantages and disadvantages.
Used engine oil is difficult to dispose of and, in many places, illegal to dispose of outside of restricted areas such as licensed garages. However, engine oil and boiler fuel oil are not significantly different and boilers can burn a variety of grades of fuel, including engine oil when it's prepared correctly. Because boiler fuel oil is becoming more expensive every year, finding a cheap and reliable alternative, such as filtering used engine oil, is ever more important. By learning how to convert engine oil to boiler fuel oil you can reduce the cost of heating your home significantly.
Drop ceilings, also known as suspended ceilings, consist of a suspended metal grid that ceiling panels are inserted into. One specific type of panel is the light panel. These are translucent panels that diffuse the light from fluorescent or incandescent light fixtures mounted above the drop ceiling. If your drop ceiling uses 2-by-2-foot panels, you may need to trim 2-by-4-foot light panels to make them fit. This is a relatively easy job to do.

Fluorescent lights have an advantage in energy efficiency over incandescent lighting. Fluorescent lights can produce 50 to 100 lumens/watt, compared to about 15 lumens/watt for incandescent bulbs, according to according to Georgia State University. Fluorescent lights activate mercury, which then causes the phosphor coating on the bulb's interior to glow. Some factors, however, may cause the lights to come on slowly.
Electricity is not a given. The power utility can fail because of severe weather conditions, damaged power lines and breaker malfunctions, among other reasons. A power failure can be inconvenient and even dangerous; some people rely on medical equipment that requires power. Air conditioners, too, are lifesavers during hot summer months when people spend a lot of time indoors; and without a refrigerator, you'll risk food spoilage. It is wise to have a plan for electricity that keeps you going for a while in the event of an emergency so you are not caught unprepared.
Fluorescent light boxes are recessed in the ceiling and often have semi-transparent plastic covers over them. Older versions, while durable, are often unattractive and detract from the look of a modern kitchen. To improve the look of the kitchen, consider removing the old light box and replacing it with a new one. If you choose a new fluorescent light that is the same size as the old one, very little extra work is required.
A six brick stove is a useful camping device for those seeking something more refined than an open campfire. With just a few materials, you can create a stove with high heat and low consumption of firewood. Similar styles of stoves are commonly built in refugee camps for their efficiency and simplicity, according to the Household Energy Network.
Stick welding refers to the common welding system that uses an electrode designed to be burnt away as it channels electricity. As the electrode burns, its coating produces flux gases to protect the weld from oxygen; the welder replaces electrodes as needed throughout the project. Stick welding is an easy type of welding to learn and practice and is used for iron and steel-based metals. AC and DC current are the two stick welding power options.

Wall ovens are very similar to traditional stove ovens except for their placement. While they may not have a stovetop and may be easier to reach on the wall, they still use the same type of systems for heating, whether it is natural gas or an electrical heating element. A growling noise inside your wall oven indicates that one of the components is not working properly. Common causes are fan issues or burner problems.
Electronic amplifier designs come in several distinct classes, such as Class A, AB, B and C. Class A has the highest fidelity but the lowest efficiency, Class B's efficiency is better but it has less fidelity; generally, each class has more efficiency and lower fidelity than the one before. Class AB circuits have a practical combination of good fidelity and efficiency at a reasonable cost.
Although they are frequently in the shape of tubes, fluorescent lights are properly called lamps. Fluorescent light numbers measure the width of lamps in eighths of an inch, so a T8 lamp is 1 inch wide. High bay fluorescent lights are designed to be used in light fixtures that are more than 20 feet above the floor.
Isolation techniques are essential for several types of examination that require samples to be separated from each other. This isolation allows researchers to study samples without interaction to other samples and to gather a better understanding of the traits of each sample and how those traits affect both the sample and the environment in which the sample exists. Isolation occurs in a variety of sciences, including chemistry, biology, computer science and electronics.
Drop ceilings have their place, but many people choose to remove them at some point and open up the full height of the room. You may uncover a beautifully finished ceiling, especially if the drop ceiling is not original to the house, or you may discover a raw, unfinished mess. You can work with either situation depending upon the look you want, but if you prefer fluorescent box lights, the fixture style is key to making them work.
Many stores carry a multitude of power strips, all designed for different purposes. Smart strips, which are highly touted by energy experts and manufacturers, advertise cost and functional benefits over traditional power strips.

Cooper Industries manufactures the Portfolio line of light fixtures. Most often found in commercial buildings, Portfolio flash mount lights are also a good choice for some residential applications. Like any other light, the bulbs require replacement from time to time. Accessing a light bulb in a Portfolio flush mount light is similar to accessing the fan in a bathroom exhaust vent. Accessing the light bulb involves removing the cover from the fixture.
A bare bulb has all the decorative beauty of a janitor's closet. The glare from a bare bulb casts awkward shadows and can make activities such as watching television or reading difficult. While a naked light bulb jutting from the ceiling may be fine for a closet, you want something with a little more ambiance and appeal for your home. Fortunately, you can convert that bare bulb to a hanging light.
Engineered to lift and lower the bed of a truck, an electric dump hoist employs an electrical switch activating a hydraulic piston. Lifting capacity of a dump hoist is determined by the size of the hydraulic piston; specifically the amount of fluid the piston is capable of displacing. Increasing power of the hoist requires replacing the existing piston with one having a greater displacement capacity that is able to force a larger amount of fluid through the hydraulic system.
Fluorescent lighting fixtures come in many shapes and sizes, including ceiling-mounted compact fluorescent lights. According to Sea Gull Lighting, a significant feature of fluorescent lighting, particularly in the form of Energy Star fixtures, is that it reduces the use of energy, thereby also potentially reducing power bills. Saving energy is a means to reducing greenhouse gas emissions as well. These savings are a bonus for environmental protection just as recessed fluorescent lighting is a bonus for residential and commercial users alike.
If you're ready to redesign your kitchen, consider track lighting. These versatile lights allow you to light whichever part of your kitchen needs it and give a modern, stylish look to your eating and cooking areas. If you currently have fluorescent lights in your kitchen, you can replace the fixtures with track lighting yourself.
There are several types of fluorescent wall-wash lighting fixtures that can be utilized to bathe a wall in light. Regardless of the type of fixture you decide to use, if it is not installed correctly, the light it gives off can detract from the wall along with any paintings or objects that it is meant to illuminate. The type of fluorescent light bulb installed in the fixture will also affect the overall appearance.
Direct current is electrical current that comes straight from a power source, like a vehicle or laptop battery. A DC to DC converter is a circuit that allows direct current from one source to power another object. Car cell phone chargers and laptop battery chargers are examples of DC to DC converters. DC to DC converters are commonly sold as a single unit. However, they can also be built from parts if need be. It takes approximately 30 minutes to make a DC to DC converter from parts.
Attics are typically unoccupied rooms that house electrical wiring, air handlers and duct work. Since attic temperatures can become hot during the day, most people wait until the evening before entering their attic, making lighting necessary. When placing open-faced fluorescent lights inside your attic, be sure insulation does not come into contact with the hot bulb. Hot light bulbs are a common cause of attic fires in residential homes.

Electrolytes are defined as any solution that can conduct ions, thereby producing electricity. Although commonly thought of as being found in sports drinks and performance products, electrolytes are any acid, base or salt, and can be found in many fruits and vegetables. Electrolytes act as a catalyst to generate an electric current when in direct contact with metal electrodes, which are conductors of electricity. The chemical reaction that is initiated between the electrolyte and electrode generates enough energy to power a small light bulb. You can show this reaction using a variety of metals as electrodes and experimenting with different…
Redox titration, a chemical analysis, involves an oxidizing agent and a reducing agent. A titration takes a known solution and adds a solution with an unknown strength to identify what the unknown solution strength is. Redox reactions are used to transfer electrons between chemical compounds. Oxidation occurs when the electrons are moved to the reducing agent. For redox titrations, during the oxidation and reduction state, the color of the indicator is different. If you have an unknown solution, you can find the redox indicator and voltage using a known solution.
Recessed fluorescent lighting has been the standard for energy-efficient illumination for decades. That changed when long-life LED tubes that used 40 percent less electricity became available. Now that those tubes have dropped in price, LED lighting has all the advantages: flicker-free performance, five years or more of expected service, instant on and off and the added safety of ballast-free operation.
Growing plants in a greenhouse environment can be tricky. Greenhouses need to have ideal growing conditions that mimic those the plants would otherwise experience outdoors. To this end, grow light manufacturers offer a variety of light bulbs with varying levels of luminosity. Generally speaking, the higher the wattage of bulb, the larger the area it will cover in the greenhouse. Therefore, the size of your greenhouse should ultimately determine what wattage you will use. A 1000-watt light bulb will cover a greater area than common 400- and 600-watt bulbs.
Certain CPU models have the core multiplier locked to prevent overclocking and underclocking. The core voltage of a locked CPU is automatically adjusted by the operating system to conserve power. If you want to find out the core voltage of a locked CPU, you must use an application such as SpeedFan, HWMonitor or CPU-Z. These applications can automatically calculate the core voltage of a CPU at any given time.
Boilers are heating devices in residences and commercial buildings that generate heat using hot water and steam. For people living in large towns and cities, oil, electricity and natural gas are most commonly used as fuel for boilers and furnaces according to the U.S. Department of Energy (DOA). However, people living in rural areas may be more prone to use wood and propane as heating fuel. Combination wood and propane boilers can also be cheaper and more efficient options for occupants with only one chimney flue, or with older fossil fuel boilers that need to be replaced.
Air gaps can refer to several key spaces when installing and using light bulbs. Fluorescent lights have a type of air gap within their circuitry that is needed for proper operation. The size of this air gap does not depend on where the light is located, but on the type of fluorescent light and how it is being used. Other air gaps might be necessary for special uses of the bulb.
More commonly known as an adapter, a high-power AC to DC converter is a fairly simple electronic device when you want it to be. For example, some might exist only to convert AC current while others are built to last. To obtain the converter that is best suited for your needs, the best way is to design and build one yourself. Taking on this kind of project requires knowing how to handle electronics and how to solder equipment.
Grounding rods are used to protect barns, homes and other structures from lightning. The rods are made of various materials that can safely carry current away from the structure. If you have an antenna on your rooftop, you must have a ground wire leading down to the grounding rod, also known as an earth rod.
LCD -- short for liquid crystal display -- uses thousands, in some cases millions, of tiny liquid crystals to generate the colors you see on your Philips TV screen. The problem is that these liquid crystals and the pixels they form are vulnerable to damage or even software issues that can cause monochromatic vertical lines on the screen; in many cases, you likely did nothing wrong to cause this issue.
A bare lightbulb adds a harsh, bright light to your room, but it offers plenty of opportunities for decor. Whether you purchase a decorative lamp shade or create your own handmade covering, you'll turn a bright, bare bulb into a decorative focal point, and shade some of the bulb's harsh light. Shading a bare lightbulb also cuts down on glares caused by the direct light.
Fluorescent lights require a steady stream of correctly modulated power to operate. That's why they have ballasts -- small electronic devices that provide the steady power the lights need to operate. Ballasts are classified according to their power output and the type of tubes with which they'll be paired. If your fluorescent tubes are flickering on and off, it's usually a sign of a bad ballast. The T8 ballast is one of several types of ballasts commonly employed with fluorescent tube fixtures and can be replaced if the original is no longer functioning.
In the United States, how we produce and consume energy has become a matter of increasing concern. The average American household uses most of its power to heat water, to heat the interior air and to power lights and electrical appliances, and most of that power comes from three sources: electricity, natural gas and fuel oil.
