Electric power

With so much emphasis on investing into alternative energies, it’s worth taking a look at the financial feasibility of them. Can wind energy compete with oil in terms of profit? How much electricity do wind turbines produce and how much do they cost to produce it? How do wind turbines work? Electricity from wind turbines is produced when wind turbine blades are pushed by the wind. The moving blades are connected to a generator and when moved, the generator creates electricity. The electricity is transferred across power lines and distributed to homes. If there is not enough wind to supply the needed electrical power, a backup power plant provides the remaining necessary electricity. The average cost for industrial wind turbines is estimated…

fuels. Another challenge has been substantial repercussions from climate change policy on the electrical power markets. This challenge has resulted in the need for addition of intermittent energy sources such as wind and power. Integration of renewable energy sources (RES) is hampered by the fact that most distribution networks have a very low degree of monitoring and automation. These challenges led to an urgent need to come up with a power grid that rises up to these challenges. A class of…

However the electric power that can be transmitted between two locations on a transmission network is limited by several transfer limits such as thermal limits, voltage limits, & stability limits with the most restrictive applying at a given time. If any such limit reached, the system is said to be congested. Congestion in a transmission system whether in vertically integrated or unbundled electric system cannot be tolerated except for a short time, since this may cause outages with…

The light bulb is one of Thomas Edison’s most famous engineering innovations. However the “Wizard of Menlo Park” (a name which he was also known as) has created and/or designed so many more inventions than just the light bulb. He has about 2332 patents worldwide proving he was really a great inventor. However, what proved his amazing skilling creating/designing are the useful products that are used throughout society till date. Edison’s inventions/designs such as the first electrical power grid,…

His invention was first used on the ‘Columbia’ a steamer belonging to the Oregon Railroad and Navigation Company, after Henry Villard, the president of the company saw Edison’s invention in action. Thomas Edison later developed and patented a system for generating and distributing electricity, which would be capable of supplying houses, factories and streets with power. When he founded the Edison Illuminating Company on December 17th 1880. His company established themselves on Pearl Street…

Sometimes, follow the electronic engineers to replace the off-line power meter. This helps me develop my interpersonal skills and power usage measurement methods between different customers in China. Power distribution room is supplied for resident area; special transformer room is supplied for industrial. Those rooms are all connected to the Transformer substation, but between different rooms the network connection is different and complex. This would benefit to decrease power loss and keep the…

its boundaries. Q. Does CRR have such an ordinance? A. Yes, they do. CRR Ordinance Number 81-2, Article VII, titled ‘Subterranean Power Lines’ reads: All electrical distribution lines, conductors and conduits installed by PNM after June 1, 1981, within the City, shall be placed underground, provided that the City may, in its discretion, grant permission, by vote of the Governing Body or its designated agency, to PNM for the erection of overhead distribution facilities.…

First, having a good purpose and goal for my career is fundamental. According to Aristotle’s virtue ethics, telos is the first and fundamental element to achieve happiness in human’s nature. In my own field, for example, if I get a chance to be a power electrical engineer fortunately, designing and creating more efficient and safer transmission and distribution circuits will be purpose and goal for me. Because if the goal is realized, it will contribute to developing our human society. In…

By Brigid Garrett , Wyatt Mullings, Jesus Sanchez, and Lydia Blaisdell Cable Sensation Russky Bridge, Vladivostok, Russia. What are Cable/Stayed Bridges? A cable/stayed bridge is a bridge that has two towers with cables supporting the bridge itself, as shown above. The towers are called pylon, the crossing area itself is called the roadway. The cables are obviously called cables. The supports underneath on the sides are called abutments, The foundations are located under the ground on the…

Are EMF's influencing me? Earthing keeps EMF's or electromagnetic field charges that are going through our bodies from having a negative impact. The wiring in our homes and work environment transmit and get these electromagnetic fields. Also, numerous things add to our electromagnetic surroundings: mobile phone towers, WiFi, remote switches, satellite TV and cordless telephones. These gadgets additionally acquaint critical spikes with the electric field in the wiring, when turning on or off. …
